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.

Our study includes four aspects. In the first aspect we study several important conditions of porcine oocytes maturation in vitro and oocytes cleavage after parthenogenetic activation and found mNCSU-23+15IU/mlPMSG+20IU/mlHCG+15% PFF+0.57mMcysteine is a good culture condition .When the Cocs are cultured in it ,the maturation rate and oocytes cleavage rate are higher than those of foreign covered. Our result are (86.7±3.35)% and (86.3±4.16)% and the highest report of foreign is(85.7±4.1)%.In the second aspect we study the effect of different chemical activations on development of porcine parthennogenetic embryo and found two best activation method. The first one is that putting the maturation MII oocytes in the 20μmol/L ionomycin for 30 minutes and then putting them in the NCSU-23 condition containing 5μg/mICB and 5mM/L6-DMAP for 3.5 hours, the oocytes cleavage rate and morulae/blastocysts development rate are (76.7±7.6)% and (37.1±6.4)%.The second one is that putting the maturation MII oocytes in the 200μM/L Thimerosal for 20 minutes and then putting them in the NCSU-23 condition containing 8mM DTT for 30 minutes
