Origin of t cells

Witryna9 maj 2024 · Both originate from stem cells in the bone marrow before migrating to the thymus, where they mature and differentiate into CD4+ and CD8+ T cells. All T cells express T cell receptors (TCRs) on their surface, and they also express CD4 or CD8 co-receptors, depending on their function. WitrynaMain arguments for transdifferentiation were the failure to detect apoptotic smooth and the unknown origin of striated muscle cells during esophageal myogenesis. To reinvestigate this issue, we analyzed esophagi of 4-day-old mice by electron microscopy and a fine-grained sampling strategy considering that, in perinatal esophagus, the ...
