ABSTRACT
Objective To investigate the effects of rhBMP2 on the differentiation of human dental pulp stem cells and expression of Delta protein in vitro. provide a theoretical basis for research on human dental pulp stem cells. Methods Monocell suspension was separated from the human adult dental pulp with collagenase Ⅰ and dispase digestion.Clonogenic cells were observed under light microscope and the expressions of surface markers were determined with immunofluorescence. divided into experimental group (containing 50 ?g?L-1rhBMP2 in the culture medium) and negative control group (containing culture medium only).alkaline phosphatase and the expression of Delta proterin of the cells at at passage 5 were detected.Results The human dental pulp stem cells showed colony growth,the nestin and vimentin staining were positive by immunohistochemical staining.STRO-1 was positive in cells by immunofluorescence.Compared with negative control group, the activities of alkaline phosphatase increased after treatment with rhBMP2 for 7,14 and 21d(P
