CF062 is a recombinant murine LIF. LIF is known for its ability to maintain the pluripotency of mouse embryonic stem cells by suppressing spontaneous differentiation.
Leukemia inhibitory factor (LIF) is the most pleiotropic member of the interleukin-6 family of cytokines. LIF derives its name from its ability to induce the terminal differentiation of myeloid leukemic cells, thus preventing their continued growth. LIF promotes long- term maintenance of embryonic stem cells by suppressing spontaneous differentiation. LIF 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.
