J . One uncommon condition called Hirschsprung's disease is characterised by failure of migration of ganglion cells into the GI tract, usually in the rectum and distal colon. https://doi.org/10.1016/j.ydbio.2016.06.042 (2016). 2008 Aug;40(5):470-4. doi: 10.1080/00313020802198028. 2b, as previously described21. . For instance, there is an increased chance that a couple will have a child with Hirschsprung's disease if one of the parents has the disease. 89, 5770. We found that SHG and 2PAF signals enabled the overall tissue morphology and structure to be visualized, and specifically allowed us to locate the submucosa layer and neighboring tissue region (muscularis) potentially containing ganglion cells. Implementation of algorithms: M.A.S.O. At 24 weeks of gestation, most of the enteric ganglion cells are very small and immature. Hirschsprung's disease occurs five times more frequently in boys than in girls. The gray shadows represent1 standard deviations (SD) over the average values. Figure9 shows the PCA-LDA plot and the corresponding H&E images with yellow arrows highlighting the ganglion cells, as determined by a pathologist, and numbered locations corresponding to the positions where Raman spectra were acquired. protein, lipids, amino acids, nucleic acids), the optical signatures in a Raman spectra can provide a wealth of multiplexed chemical information for accurate identification and discrimination of biological specimens16,17. J. Biophoton. With an excitation wavelength of =940nm, the laser beam was focused into the sample with a 40X air objective (N.A. Our surgeons frequently perform a single operation to fix intestinal obstruction when Hirschsprung's disease is initially diagnosed. water immersion objective lens (Olympus, UPlanSApo). Carousel with three slides shown at a time. Human intestinal organoids (HIOs) derived from iPSCs hold great promise for regenerative medicine. Those affected with this birth defect are missing intestinal nerve cells called ganglion cells. What is a ganglion cell . Colon from 3-week-old C57/BL6 wild type mice were used in this study. ISSN 2045-2322 (online). Hirschsprung's disease is the congenital absences of ganglion cells in the rectum and the lack of these cells causes an obstruction of the large bowel. A specimen from submucosal biopsy of the colon is very small and difficult to identify submucosal ganglion cells. Diagnosing Hirschsprung disease by detecting intestinal ganglion cells using label-free hyperspectral microscopy. sharing sensitive information, make sure youre on a federal The axons of ganglion cells form the optic nerve. Movasaghi, Z., Rehman, S. & Rehman, I. U. Raman spectroscopy of biological tissues. Plant extracts can have antioxidant action; however, the specific phytogenic active ingredients and their potential mechanisms are not well known. Drug Deliv. Symptoms vary with age. J. Histochem. Background. HD mortality rates up to 20% have been reported. Instead of using spectral signals from only a single Raman image pixel, signals from areas of 2 by 2 image pixels were averaged to produce a single Raman spectrum, which increases the signal-to-noise ratio (SNR) and yields more reproducible data while still retaining high spatial resolution. Intestinal enzymes break down foods inside epithelial cells of the mucosa Intestinal Digestion: Calretinin and microtubule-associated protein-2 (MAP-2) immunohistochemistry in the diagnosis of Hirschsprung's disease. 8600 Rockville Pike 25, 9. https://doi.org/10.5812/ijp.367 (2015). As they exist outside of the CNS, they are sometimes referred to as peripheral ganglia. Zipfel, W. R. et al. As expected, the submucosa region, which emit strong SHG signals due to the presence of collagen, exhibit strong Raman signals at 923, 938, 1056, 1235, 1286, 1309 and 1332cm1, all known Raman peaks associated with collagen24. Am. The goal of the surgery is to remove the diseased section of the intestine and to pull the healthy portion of the intestine down to the anus. Google Scholar. Briefly, a Ti:Sapphire tunable (=7501000nm) femtosecond laser, with a temporal resolution~140fs, was used as the excitation source. originally, any nerve cell (neuron); in current usage, a neuron the cell body of which is located outside the limits of the brain and spinal cord, hence forming part of the peripheral nervous system; ganglion cells are either 1) the pseudounipolar cells of the sensory spinal and cranial nerves (sensory ganglia), or 2) the peripheral multipolar motor neurons innervating the viscera (visceral or autonomic ganglia). Although specimens from wild type mice were used in this study, our results lay the foundation for establishing the optical signatures of ganglion cells and intestinal tissue that will be of paramount importance for future planned studies using tissue specimens from a knockout mouse model of Hirschsprung disease. To make a definite diagnosis, biopsy of the aganglionic zones of colon is required. 15, 3038. https://doi.org/10.1038/s41598-021-80981-7, DOI: https://doi.org/10.1038/s41598-021-80981-7. The second classification model used in this study is based on SVM, which is a method of discrimination commonly used for pattern recognition in machine learning technology18. Hirschsprung disease (HD) is a congenital intestinal motility disorder affecting 1 in 5000 new babies in the United States annually1. Observe the ganglion cells and nerve fibers of the myenteric (Auerbach's) plexus View Image located between the two muscle layers. Extensive involvement of the small bowel is very rare. https://doi.org/10.1016/j.bpj.2015.11.2334 (2016).

Bookshelf First, SHG and 2PAF multiphoton imaging, with its high resolution optical sectioning capability, would be used to image the overall tissue architecture, to identify the tissue layers of interest and to pinpoint regions potentially containing ganglion cells. Often, a serious infection called enterocolitis can occur, which causes fever, pain, and diarrhea. Most newborns will have the following tests: There are other tests that, when abnormal, suggest that Hirschsprung's may be present. Hirschsprung's disease (also called Hirschsprung Disease or HSCR) is a rare condition in which a baby is born without nerve cells (known as ganglion cells) in the lower part of the intestine. Rev. 58, 320337. Nat. These problems depend on how much unhealthy intestine needed to be removed during surgery and the current functioning of the colon, rectum, and anus. According to the literature, the gastrointestinal tract is primarily dominated by three kinds of sensory neurons: DRG (spinal nerve afferent), ganglion/cervical ganglion (vagus nerve afferent), and intrinsic primary afferent neurons (IPANs) (see Figure 1) ( Lai et al., 2017 ). The abdomen, including an exteriorized segment of jejunum, was housed in a humid chamber with a viewing window. Dead tumour cells and inflammatory cells can be seen in the centre of the gland. In this study, to ensure the optical signatures are assigned accurately to the ganglion cell and other regions of the tissue, detailed experiments were carried out in which label-free images were directly correlated to H&E images and the classification results based on the label-free spectral data were compared to the diagnosis by a pathologist. Diagnostic accuracy, sensitivity and specificity were calculated. However, because the negative 2PAF contrast, alone, was insufficient for reliably identifying ganglion cell areas, we used hyperspectral Raman microscopy to acquire more spectral and chemical information. We screened 845 phytogenic compounds using a porcine epithelial cell (IPEC-J2) oxidative stress model to identify oxidative-stress-alleviating compounds. Surg. Furthermore, animal models have been widely used and are useful resources for research in disease development, diagnostics and therapeutics study of human diseases25. Careers. A neuron the cell body of which is located outside the limits of the brain and spinal cord, hence forming part of the peripheral nervous system; ganglion cells are either 1) the pseudounipolar cells of the sensory spinal and cranial nerves (sensory ganglia), or 2) the peripheral multipolar motor neurons innervating the viscera (visceral or autonomic ganglia). To obtain Future research will involve human patient specimens as we advance the technology towards clinical implantation. All animal use and welfare in these studies adhered to the National Institutes of Health Guide for the Care and Use of Laboratory Animals following protocols reviewed and approved by the Institutional Animal Care and Use Committee (IACUC) of the University of California, Davis under IACUC Protocol #20942. Soares de Oliveira, M.A., Galganski, L., Stokes, S. et al. The first few PCs typically account for the majority of the data variance. Mice with a recessive gene which reduces the number of ganglion cells of the large intestine and produces megacolon similar to Hirschsprung's disease were studied. Understand the consequences of disease of the large intestine. These imaging modalities are simple to implement simultaneously with the proper choice of optical filters and detector placement. 8d) suggesting the presence of ganglion cells in that area, the Raman spectral data shows no ganglion cells present (Fig. Article The first is a total absence of ganglion cells in each the submucosal and myenteric plexuses. A. Colon Slide UMich 176 40x (colon, H&E) [DigitalScope] The mucosa of the colon is lined by a simple columnar epithelium with a thin brush border and numerous goblet cells. CAS Intramucosal ganglion cells in normal adult colorectal mucosa. Hirschsprung's disease (also called congenital aganglionic megacolon) occurs when some of your baby's intestinal nerve cells (ganglion cells) don't develop properly, delaying the progression of stool through the intestines. 1998 Aug;122(8):721-5. The ganglion cells form the network of nerves called the myenteric plexus (Auerbachs plexus) that are located in between the circular and the longitudinal muscle layers of the gastrointestinal (GI) tract wall. If a family has a child with Hirschsprung's disease, there is a 3 to 12 percent chance that another baby from the same parents will also have the disease. ADS Raman spectroscopy is also a powerful label-free technique based on inelastic scattering of light by vibrational modes of molecular bonds. Our findings suggest that a near real-time intraoperative histology method can be developed using these three optical modalities together that can aid pathologists and surgeons in rapid, accurate identification of ganglion cells to guide surgical decisions with minimal human intervention. Data collection: M.A.S.O., C.C., and B.Z. The tumour starts from the tissue that lines the inside of the nasal cavity or the paranasal sinuses such as the ethmoid or maxillary sinus. The postsynaptic cell then goes on to innervate the targeted end effector (i.e., gland, smooth muscle, . Raman spectroscopy in head and neck cancer. Hirschsprung's disease: is there a relationship between mast cells and nerve fibers. Am. The primary treatment for HD is surgical intervention with resection of the aganglionic bowel. 1, 154169. https://doi.org/10.1002/jbio.200710005 (2008). J Pediatr Surg. The diagnosis of neuronal intestinal dysplasia should rely on a constellation of clinicopathological features. Children with HD lack vital intestinal nerve cells, or ganglion cells, which are responsible for normal motility and the ability to stool. Opt. & Foroutan, H. R.

Raman and FTIR microscopic imaging of colon tissue: A comparative study. It can be applied to the suction submucosal biopsy in a patient suspected of having Hirschsprung's disease, therefore, the complicated full thickness colonic and rectal biopsy can be avoided. This process can be time-consuming and technically and diagnostically challenging as it requires multiple processing steps (e.g., tissue freezing, sectioning and staining) which introduce tissue artifacts and extend anesthesia and intra-operative time2,3. Intestinal-type sinonasal adenocarcinoma (ITAC) is a type of head-neck cancer. Six antineural markers, peripherin, cathepsin D, PGP 9.5, synaptophysin, chromogranin and S-100 protein, were used. Two multivariate statistical analysis techniques, PCA and LDA, were used to build one of the two classification models in this study, as previously described21. Article Our study reports an immunohistochemical technique to detect submucosal ganglion cells. 42, 493541. 1b, for label-free SHG/AF/Raman imaging without any further treatment. Every Raman spectrum was a 1340-dimensional vector that was classified and assigned to a group by using the previous Raman data as the training set. The ganglion cells are not fully mature and lack satellite cells and Nissl bodies. Google Scholar. https://doi.org/10.1364/boe.10.004411 (2019). Intramucosal ganglion cells are commonly believed not to occur in normal colon and to be found only in the chronic bowel motility disorder, neuronal intestinal dysplasia. Biophys. Yu, J. D., Zeng, Y. J., Zhao, J. Unable to load your collection due to an error, Unable to load your delegates due to an error. Ancillary to H&E histology, numerous histochemical and immunohistochemical staining techniques, such as acetylcholinesterase (AChE) and calretinin, have emerged but none of them have still been effectively established in routine intraoperative diagnoses mostly because of their lengthy processing times6,7. Springer Nature remains neutral with regard to jurisdictional claims in published maps and institutional affiliations. However, because other non-ganglion cell regions in the 2PAF image in Fig. 5ai) to determine if the multiplexed Raman spectral information has higher specificity for identifying ganglion cells. 1996 Jan-Feb;16(1):51-70.

HHS Vulnerability Disclosure, Help Thus, mutations in these two genes could directly lead to the absence of certain nerve fibers in the colon. These babies may present at birth a delay to pass meconium (a dark green poop in newborns) for more 24 hours or have abnormal bowel movements associated with abdominal distention and vomiting . Fortunately surgery corrects this problem. frequent episodes of infections (enterocolitis), severe abdominal distention (a very bloated stomach), medications to either slow the transit of the stool in the colon or to make it faster, injections of Botulinum toxin (Botox) into the anal sphincter to relax this muscle, other rectal interventions or surgical procedures that may include redoing previous operations, appendicostomy, a surgical procedure to flush out and empty the colon by creating an opening outside the belly. Their axons gather at the optic disk, where they become myelinated and form the optic nerve. On comparison with the neuroanatomically normal zone of HSCR, the cut-offs to identify hypertrophic nerve trunks (nerve trunk thickness of >37.85 m) and reduced number of ganglia (number of ganglia/linear mm of colon <2.05 and interganglion distance of >229 m) were derived. Internet Explorer). Currently, hematoxylin and eosin (H&E) histopathology is the gold-standard for intraoperative HD diagnosis and requires surgical biopsies at multiple levels of the bowel to identify the extent of abnormal intestine. The nature of the ganglion cells was confirmed by positive neurone specific enolase staining by the peroxidase-antiperoxidase technique in all cases. https://medical-dictionary.thefreedictionary.com/ganglion+cell. =0.9). An increased number and density of the so-called "giant ganglia" (seven or greater ganglion cells per ganglion) serve as histopathological criteria for a bowel motility disorder called intestinal . Children with Down syndrome have a higher risk as well. Your surgeon can discuss different surgical techniques with you to determine the best option for your child. (a) Brightfield image from an H&E stained tissue section. Article The results of two classification approaches, PCA-LDA and SVM, showed that Raman spectral markers exist for accurately identifying ganglion cells, when compared to conventional H&E histology. This disease affects 1 in 5,000 babies and is more common in boys than in girls. Support vector machine, principal component analysis and linear discriminant analysis classification models were applied to the hyperspectral Raman data and showed that ganglion cells can be identified with a classification accuracy higher than 95%.

Real-time intraoperative diagnosis by deep neural network driven multiphoton virtual histology. These nerve cells allow the intestine to relax so stool (poop) can pass through the intestine and out of the body. However, the conventional method employs manual pick up of liberated free-floating hindgut spheroids, resulting in variability in their yield and cell composition. https://doi.org/10.1073/pnas.95.9.5161 (1998). The authors declare no competing interests. Patient management could be significantly improved if a reliable, real-time intraoperative diagnostic method was available that could more rapidly and accurately detect intestinal ganglion cells.

They graduated from Pikeville . called ganglion cells or postganglionic neurons, . Adjacent tissue sections of full thickness colon were prepared to allow for direct comparison of the label-free SHG/2PAF/Raman multimodal images with the H&E images, which serve as the gold standard method for identifying ganglion cells. HD presents as functional intestinal obstruction from the incomplete migration of neuroblasts from the neural crest and inadequate differentiation of neuroblasts to ganglion cells in the intestine . The large amount of information contained in the spectral data has been vastly exploited by using chemometric (multivariate mathematic and statistic) techniques such as principal component analysis (PCA) and linear discriminant analysis (LDA) to provide classification and quantification of the multidimensional spectral data. Retinal ganglion cells (RGCs) are the cells that are responsible for transferring information from the eye to the brain. J. Surg. Neverthe-less, our data suggest that the counts of neurons and glial cells in a limited number of sections are representative estimates to quantify ganglionic cells (either neuronal cell All authors reviewed the manuscript. https://doi.org/10.4081/ejh.2014.2461 (2014). Using the SHG signal from the connective submucosa layer as an initial guide, the muscularis layer (above the SHG line) and the mucosa (below the SHG line) are identified. Eur.
