RNA sequencing aligns M-ATO-derived populations with phenotypically identical ...
Webb4 aug. 2016 · Here, we assessed thymopoiesis longitudinally over a 1-year period prior to and after long-term space flight (median duration, 184 days) in 16 astronauts. While preflight assessments of thymopoiesis remained quite stable in individual astronauts, we detected significant suppression of thymopoiesis in all subjects upon return from space … Webb24 feb. 2024 · Thymopoiesis is the best-studied example of the fact that hematopoiesis does not end at the boundary of the sinusoidal endothelium in the bone marrow.
