WebThe MAPKs are a family of serine/threonine kinases that play an essential role in connecting cell-surface receptors to changes in transcriptional programs. MAPKs are part of a three-component kinase module consisting of a MAPK, an upstream MEK, and a MEKK that couples the signals from cell-surface receptors to trigger downstream pathways. WebHematopoiesis is the process by which a small pool of self-renewing pluripotent HSCs produce red blood cells, platelets, and all leukocyte types. Only 1 of about 10 000 bone marrow cells is an HSC, 11, 12 and these cells are comparatively quiescent with fewer than 5% of them being in cell cycle at any point in time. def head assembly https://craftach.com
