Abstract
The present invention relates to a cell culture medium for preparing liver, gastric, pancreatic, colon or intestinal adult stem cell isolated from adult tissue, as well as for maintaining such stem cell in the undifferentiated state. The cell culture medium comprises a base medium; an ABL and SRC dual kinase inhibitor/an ABL kinase inhibitor and a SRC kinase inhibitor; a mitogenic factor; a WNT signalling pathway activator; a stimulator for NAD+ and NADP+ generation; and a cAMP/PKA pathway activator. In a particular embodiment, the ABL and SRC dual kinase inhibitor is Dasatinib; the mitogenic factor is EGF; the WNT signalling pathway activator is R-Spondin 1; the stimulator for NAD+ and NADP+ generation is nicotinamide; and the cAMP/PKA pathway activator is cholera endotoxin.
