Background

LIF is a pleiotropic cytokine with a variety of roles. It is involved in the induction of hematopoietic differentiation in normal and myeloid leukemia cells, induction of neuronal cell differentiation, regulator of mesenchymal to epithelial conversion during kidney development, and may also have a role in immune tolerance at the maternal-fetal interface (PMID: 29620145; 29391217; 29271384)
