【Abstract】 In the present study 25 ×105 cells were obtained from the oalvaria of 22 days rat embryos through isolation of oollagenase II and two 60 mine treatment at 50 osoillations/min at 37℃. The cells grew well at 0.5ml cell suspension (1×105 cells)in culture flask with 3.5ml EMEM and 10% FBS. The osteoblasts were relatively large cells that exhibited basophilic cytoplasma and cytoplasmic processes. The processes joined with the processes of neighboring cells. The shape of osteoblasts appeared trigonal, polygonal and ouboidal. The membranes showed positive reaction with ALPase dye. The cells were demonstrated to contain, calcium by electric microscopic X analysis.更多还原
