Background:

Synonyms: Differentiation-stimulating factor (D factor), Leukocyte Inhibitory Factor, Melanoma-derived LPL inhibitor (MLPLI)

Background: Human Leukemia Inhibitory Factor (LIF) is member of the IL-6 family and is made by a variety of tissues. Human LIF signals through gp130 to activate STAT3 in human ESCs . In mouse ESCs, LIF promotes self-renewal and pluripotency, but in human cells there is no indication that LIF has the same function. Instead, FGF-basic (FGF-2) and Activin A are used to promote self-renewal and pluripotent potential. Recombinant human LIF is a non-glycosylated protein, containing 181 amino acids, with a molecular weight of 19.9 kDa.
