IL-10 inhibits IL-7-mediated murine pre-B cell growth in vitro.

B lymphopoiesis in the bone marrow is mediated by both positive and negative regulatory cytokines. In this report, we demonstrate that interleukin-10 (IL-10) may function to inhibit murine IL-7-dependent pre-B cell growth. Recombinant IL-10 (rmIL-10) inhibited BALB/c bone marrow IL-7 colony-forming unit (CFU) in a concentration-dependent manner, and growth… CONTINUE READING
