Viable c-Kit(W/W) mutants reveal pivotal role for c-kit in the maintenance of lymphopoiesis.

Abstract excerpt

Mice lacking the receptor tyrosine kinase c-Kit (c-Kit(W/W)) have hematopoietic defects causing perinatal death. We have identified a viable c-Kit(W/W) mouse, termed the "Vickid" mouse. Around birth, c-Kit plays a redundant role in T and no role in B cell development. Here, we show an age-dependent, progressive decline of pro-T and pro-B cells accompanied by loss of common lymphoid progenitors in the bone marrow...
