The invention integrates a variety of technologies including stem cell proliferation, directed inductioncryopreservation in vitro. This integrated system was developed under chemical defined condition,can expand various type of stem cells over one hundred foldcan furtherly induce to specific mature cells up to ten millions. In addition, the amount of cryoprotectant can be significantly reduced to 2 in the cryopreservation system with excellent cell survival rate. This integrated system can provide a promisingvarious stem cell sources for cell therapyimmunotherapy.

PPARγ is the master regulator of glucose metabolism.15-keto-PGE2 is an endogenous PPARγ ligand whitch is degraded by ZADH1. We found that increasing 15-keto-PGE2 promotes glucose uptake. We identified several ZADH1 inhibitors which could increase 15-keto-PGE2 promote glucose uptake via activating PPARγ. Our results showed that inhibition of ZADH1 is a novel approach to treat type 2 diabes mell
