[Neuropeptide Y promotes the proliferation and differentiation of 3T3-L1 preadipocytes].

To observe the effect of neuropeptide Y on the proliferation and differentiation of 3T3L1 preadipocytes and detect the mechanics.3T3-L1 preadipocytes were induced to differentiation by the cocktail medium containing 3-isobutyl-1-methylxanthine (IBMX), dexamethasone and insulin.
