Recombinant Human Leukemia Inhibitory Factor
LIF
Leukemia Inhibitory Factor (LIF) is a lymphoid factor which promotes long-term maintenance of embryonic stem cells by suppressing spontaneous differentiation. LIF binds to the specific LIFR-α, which forms a heterodimer containing a GP130 signal transducing subunit.LIF is normally expressed in the trophectoderm of the developing embryo and has a number of other activities including cholinergic neuron differentiation, control of stem cell pluripotency, bone and fat metabolism, mitogenesis of certain factor dependent cell lines and promotion of megakaryocyte production in vivo. LIF is not required for human embryonic stem cell cultures.
