Abstract:
Provided is a composition for reprogramming somatic cells to generate embryonic stem cell-like cells, comprising: a) a Bmi1 (B cell-specific Moloney murine leukemia virus integration site 1) protein or a nucleic acid molecule encoding the Bmi1 protein; and b) at least one low molecular weight substance selected from the group consisting of a set of a MEK/ERK (mitogen-activated protein kinase/extracellular regulated kinase) inhibitor and a GSK (glycogen synthase kinase) inhibitor, a set of a G9a HMTase (G9a histone methyltransferase) inhibitor and a DMNT (DNA methyltransferase) inhibitor, and a histone deacetylase inhibitor. Also, a method is provided for reprogramming somatic cells to generate embryonic stem cell-like cells using the composition. In addition to reducing the number of the reprogramming factors conventionally needed, the composition and method allow the generation of pluripotent embryonic stem cell-like cells which have high potential in the cell therapy of various diseases.
