In situ hybridization using biotinylated POMC cRNA probe made it possible to localize POMC mRNA in the rat ovary. POMC mRNA predominantly existed in corpora lutea of diesturs, pregnant and pseudopregnant rat ovaries. POMC containing cells scattered in the ovarian intertitium were seen. The amount of POMC mRNA in granulosa cells was negligible.

①Rat MSC and VSMC were cultured and identified, respectively. MSC were labeled with DAPI firstly, and then co-cultivated with VSMC. The changes of morphology and ultrastructure of co-cultured cells were observed. Immunfluorescence analysis was performed by using monoclonal antibodies against specific antigen.②We established the regulatable system in two steps: a stable MSC line expressing rtTA has been constructed and characterized firstly by transfected with pUHD 17-1hyg and then selected by hygromycin B; in a second step, this line was used for trandfer the AT2R gene to MSC to get the well establishing double stable MSC lines;③The expression of AT2R regulated by doxycycline was evaluated by western blot;④The MSCs were transduced into rat carotid arteries with regulatable AT2R gene after the establishment of rat carotid balloon injury restenosis model. The intimal/medial area ratio were measured by digital analysis system.
