Programmed Cell Death in the Developing Nervous System
Virtually all cell populations in the vertebrate nervous system undergo massive "naturally-occurring" or "programmed" cell death (PCD) early in development. Initially neurons and glia are overproduced followed by the demise of approximately one-half of the original cell population. In this review we highlight current hypotheses regarding how large-scale PCD contributes to the construction of th...
متن کاملPhenotypic expression in the developing murine enteric nervous system.
The development of the enteric nervous system was examined in fetal mice. Synthesis of [3H] acetylcholine ([3H]ACh) from [3H]choline and acetylcholinesterase histochemistry were used as phenotypic markers for cholinergic neurons, while the radioautographic detection of the specific uptake of [3H]serotonin (5-[3H]HT) and immunocytochemical staining with antiserum to 5-HT marked serotonergic neur...
متن کاملThe enteric nervous system.
T HE enteric nervous system is a collection of neu-rons in the gastrointestinal tract 1 that constitutes the " brain of the gut " and can function independently of the central nervous system. 2 This system controls the motility, 3,4 exocrine and endocrine secretions, 5 and microcirculation 6 of the gastrointestinal tract; it is also involved in regulating immune and inflammatory processes. 7 In...
متن کاملIon Channel Expression in the Developing Enteric Nervous System
The enteric nervous system arises from neural crest-derived cells (ENCCs) that migrate caudally along the embryonic gut. The expression of ion channels by ENCCs in embryonic mice was investigated using a PCR-based array, RT-PCR and immunohistochemistry. Many ion channels, including chloride, calcium, potassium and sodium channels were already expressed by ENCCs at E11.5. There was an increase i...
متن کاملCell lineage tracing in the developing enteric nervous system: superstars revealed by experiment and simulation
Cell lineage tracing is a powerful tool for understanding how proliferation and differentiation of individual cells contribute to population behaviour. In the developing enteric nervous system (ENS), enteric neural crest (ENC) cells move and undergo massive population expansion by cell division within self-growing mesenchymal tissue. We show that single ENC cells labelled to follow clonality in...
