Abstract:
[Objective]To compare the expression of calcitonin gene-related peptide(CGRP) receptor in rat bone marrow mesenchymal stem cells(rBMSCs) and the induced osteoblasts.[Method]The rBMSCs were isolated using whole bone marrow adherence method,and classified into osteoblast-induced group and non-induced group.In the different periods of culturing(1,2,and 3 weeks),identification of osteoblasts was performed by immunohistochemistry and reverse transcriptase-polymerase chain reaction(RT-PCR),and expression of the CGRP receptor was detected by Western Blot and RT-PCR.[Result]RT-PCR test demonstrated that osteoblast-induced group had a higher expression of CGRP receptor than non-induced group at the same time point,expression of CGRP receptor was increased in a time-dependent manner in the osteoblast-induced groups.Western Blot test demonstrated that osteoblast-induced group had a higher expression of CGRP receptor than non-induced group at the same time point.Expression of CGRP receptor was increased in a time-dependent manner in osteoblast-induced groups.[Conclusion]According to the mRNA test and protein test,it is suggested that CGRP receptor exists in the rBMSCs.CGRP receptor expression increased in the progress of osteogenic differentiation.
