Summary: In this study, neurospheres were successfully generated using NSM and SRM, and they were able to assemble enteric neural networks in both two- and three-dimensional environments, as well as on gut explants. The transplantation of these neurospheres resulted in the reconstitution of myenteric plexuses in the recipient's rectum. This research provides valuable insights into the dynamic nature of the ENS and opens up possibilities for further exploration and understanding of its cellular activities.

Summary: The development of the enteric nervous system relies on the interaction between enteric neural crest cells and the neural stem cell niche. Defects in ENCCs may lead to ENS dysfunction. HSCR patients may have niche defects affecting ECM-cell interaction, suggesting the need for complementary therapies involving drugs and niche-based treatments.

Summary: The interaction between ENSCs and EMCs plays a crucial role in the normal development of the enteric nervous system, with potential implications for treating Hirschsprung disease. EMCs enhance the expansion and neurosphere-forming ability of ENCDCs through paracrine factors, leading to functional neurons and successful transplantation in the HSCR model.

Summary: With the rapid development of single-cell sequencing technologies, the use of single-cell multimodal sequencing has become a powerful strategy in discovering rare cells and understanding biological processes. This article summarizes recent findings in single-cell multimodal sequencing, particularly focusing on single-cell RNA sequencing (scRNA-seq) in the enteric nervous system (ENS). The studies have revealed the heterogeneity of ENS cells at different developmental stages and identified novel cell types. The application of single-cell multimodal omics techniques in profiling disease mechanisms and cellular drug responses is expected to revolutionize biomedical research.

Summary: Hirschsprung's disease is a developmental disorder of the enteric nervous system derived from neural crest cells, and changes in gene expression may contribute to its pathogenesis. Deviant genetic and epigenetic patterns, such as DNA methylation, histone modification, and miRNA regulation, can play a role in the development of neurocristopathy. Specifically, epigenetic regulation of miRNA expression and its relationship to cellular interactions and gene activation through major pathways are discussed in the context of Hirschsprung's disease.

Summary: The endogenous peptide PDYBX1 may partially alleviate the impairment of enteric neural cells caused by the downregulation of its precursor protein YBX1 by antagonizing the inhibition of the ERK1/2 pathway. PDYBX1 could be a potential therapeutic agent for Hirschsprung's disease (HSCR).

Summary: The gut and the brain communicate through various channels and interactions, collectively known as the gut-brain axis. The aging of the enteric nervous system (ENS) in the gut can lead to gastrointestinal dysfunction and contribute to age-related diseases of the brain. Understanding the mechanisms of the aging ENS can provide insights into the diagnosis and treatment of neurodegenerative diseases like Alzheimer's and Parkinson's.

Summary: The development of the enteric nervous system is dependent on the colonization of the intestine by enteric neural crest-derived cells (ENCDCs). ENCDCs at the wavefront, which are highly migratory and proliferative, exhibit distinct molecular characteristics compared to trailing ENCDCs. These wavefront ENCDCs show altered expression of genes associated with migration and lack expression of genes related to neuronal or glial maturation.

Summary: Hirschsprung disease is a complex congenital disorder caused by defects in the development of the enteric nervous system. The use of human induced pluripotent stem cells has provided new tools for understanding the disease and developing therapies. These stem cell-based models complement traditional genetic screens and bioinformatic approaches, and have potential applications in translational medicine and drug discovery.

Summary: This study aimed to investigate the neural stem cell potential of the medial geniculate body (MGB). The findings showed that MGB cells exhibited the cardinal features of neural stem cells, including self-renewal, formation of progenitor cells, and differentiation into all neuronal lineage cells. These findings contribute to a better understanding of the development of the auditory pathway.

Summary: The role of the enteric nervous system (ENS) in drug absorption is not well understood. In this study, a co-culture system of Caco-2 cells and enteric neurons was established to investigate the effect of ENS on drug transport across intestinal epithelial cells. The co-culture was found to enhance the transport of fluorescein isothiocyanate-labeled dextran-4 via the paracellular route, suggesting that enteric neurons can facilitate drug transport by opening tight junctions. However, no changes in the permeability of antipyrine were observed, indicating that enteric neurons do not affect passive transport via the transcellular pathway.

Summary: This study compared postoperative outcomes between salvage cystectomy post-trimodality therapy, primary cystectomy, and primary cystectomy with prior history of nontrimodality therapy abdominal or pelvic radiotherapy. It was found that salvage cystectomy post-trimodality therapy had a higher incidence of late complications, but disease-specific survival and overall survival were comparable to the other groups.

Summary: Tumor shrinkage of at least 10% after presurgical targeted molecular therapy (TMT) in renal cell carcinoma (RCC) patients is associated with better overall survival (OS) outcomes. Intermediate risk score and shrinkage of at least 10% in the primary tumor, metastases, or both were associated with better OS outcomes in patients with metastatic ccRCC who underwent deferred cytoreductive nephrectomy (dCN) independent of the type of preoperative systemic therapy.

Summary: This study assessed the preoperative factors associated with overall survival in patients with renal cell carcinoma with IVC thrombus (cT2b, cT3c). The findings confirmed that cT3c, cN1, and cM1 were independently associated with poor overall survival. Patients with two or more risk factors had a shorter median overall survival.

Summary: The enteric nervous system (ENS) and peripheral ganglia provide innervation to the gastrointestinal tract, but the molecular mechanisms controlling extrinsic nerve fiber growth are not well understood. This study investigates the role of CXCR4 and CXCL12 in the development of colorectal innervation. It is found that CXCR4 is expressed in nerve fibers arising from the nerve of Remak (NoR) and the pelvic plexus, while CXCL12 is localized to the hindgut and enteric ganglia. Overexpression of CXCL12 enhances axonal projections to the gut from the NoR, while CXCR4 inhibition disrupts nerve fiber extension.

Summary: The enteric nervous system (ENS) is derived from vagal neural crest cells and plays a crucial role in gastrointestinal development. This study shows that the avian ceca, located at the junction of the midgut and hindgut, are necessary for hindgut ENS development. It also highlights the importance of bone morphogenetic protein-4 (BMP4) and glial cell line-derived neurotrophic factor (GDNF) signaling pathways in the migration of enteric neural crest-derived cells (ENCDC) and the formation of enteric ganglia.
