Together, these results suggest that loss of cell attachment and activation on the 10 kPa gel is associated with loss of early TCR signaling, whereas mechanosensing on the stiffest gels is mediated by mechanisms downstream of Lck/Fyn and Zap70. We note that for human cells interacting with B cells o ...

Lymphopoiesis
Lymphopoiesis (lĭm'fō-poi-ē'sĭs) (or lymphocytopoiesis) is the generation of lymphocytes, one of the five types of white blood cell (WBC). It is more formally known as lymphoid hematopoiesis.Pathosis in lymphopoiesis leads to any of various lymphoproliferative disorders, such as the lymphomas and lymphoid leukemias.
