Telocytes are unique mesenchymal cells characterized by multiple remarkably long cytoplasmic extensions that extend hundreds of micron away from the cell body. Through these extensions, telocytes establish a 3-dimensional network by connecting with other telocytes and various cell types within the tissue. In the intestine, telocytes have emerged as an essential component of the stem cell niche, providing Wnt proteins that are critical for the proliferation of stem and progenitor cells. However, the analysis of single-cell RNA sequencing has revealed other stromal populations and mechanisms for niche organization, raising questions about the role of telocytes as a component of the stem cell niche. This review explores the current state-of-the-art, existing controversies, and potential future directions related to telocytes in the luminal gastrointestinal tract.
期刊介绍：
"Cell and Molecular Gastroenterology and Hepatology (CMGH)" is a journal dedicated to advancing the understanding of digestive biology through impactful research that spans the spectrum of normal gastrointestinal, hepatic, and pancreatic functions, as well as their pathologies. The journal's mission is to publish high-quality, hypothesis-driven studies that offer mechanistic novelty and are methodologically robust, covering a wide range of themes in gastroenterology, hepatology, and pancreatology.
CMGH reports on the latest scientific advances in cell biology, immunology, physiology, microbiology, genetics, and neurobiology related to gastrointestinal, hepatobiliary, and pancreatic health and disease. The research published in CMGH is designed to address significant questions in the field, utilizing a variety of experimental approaches, including in vitro models, patient-derived tissues or cells, and animal models. This multifaceted approach enables the journal to contribute to both fundamental discoveries and their translation into clinical applications, ultimately aiming to improve patient care and treatment outcomes in digestive health.
