OBJECTIVE: To estlish sequencing induction system of ADSCs trnsforming into heptic-like cells. METHODS: After isolted nd purified the Lewis rt ADSCs, the surfce mrks of ADSCs were identified y flow cytometry. The rt ADSCs were trnsformed into the heptic-like cells in the procedure-culture system y tris-step including heptocyte growth fctor (FGF), firolst growth fctor-4, cid firolst growth fctor nd oncosttin M cytokine. RESULTS AND CONCLUSION: After rt ADSCs were induced t 7, 14 nd 21 dys, the expression of lumin (ALB), lph fetoprotein (AFP) nd CK18 mrna ws determined nd fortified over time. Heptic-like cells hd ALB synthesis function. Metolism of mmoni nd ure synthesis occurred nd lsted fter 912 dys. Results suggest ADSCs were successfully differentited into heptic-like cells in vitro fter procedure-induction. Liu J, Li L, Rn JH, Zhng SN, Sho JC.
