Role of Mercaptoethanol and Endotoxin in Stimulating B Lymphocyte Colony Formation in Vitro

[摘要] Mercaptoethanol is necessary to permit B lymphocyte colony formation in semi-solid agar cultures of cells from normal mouse lymphoid organs. Transfer studies on developing colonies showed that, in part, this was a direct action on B lymphocyte colony cells but evidence was produced that in the presence of mercaptoethanol lymphoid organ cells release a factor promoting colony growth.Endotoxin strongly potentiated B lymphocyte colony formation in vitro by a direct action on colony cells but in the absence of mercaptoethanol did not allow cell survival or proliferation.
