11B cell growth factors — (BCGF) factors derived from T cells that stimulate B cells to proliferate in vitro but (unlike B cell differentiation factors) do not stimulate antibody secretion. Cf. B lymphocyte stimulatory f s …
12insulinlike growth factors — (IGF) serum peptides with insulin like actions, formerly called somatomedins (q.v.). IGF I (formerly somatomedin C) is an important growth hormone–dependent mediator of cell growth and replication. IGF II (formerly somatomedin A) appears to be… …
13hematopoietic growth factors — a group of substances with the ability to support hematopoietic colony formation in vitro, including erythropoietin, interleukin 3, and colony stimulating factors. All except erythropoietin stimulate mature cells, have overlapping capabilities to …
