Abstract
To investigate the effect of concentrated growth factor (CGF) on proliferation and differentiation in Beagle adipose-derived stem cells (ADSCs). Methods: ADSCs were isolated from adipose tissue of healthy Beagles and cultured. The multi-directional differentiation potential of ADSCs was identified. The ADSCs were assigned to a CGF group and a control group. The rate of proliferation was analyzed by CCK-8 assay. The osteogenic differentiation capability was detected by ALP staining after the osteoinduction. Bone formation-related gene expression was detected by RT-PCR. Results: CGF promoted the proliferation of ADSCs in vitro. ADSCs in the CGF group showed higher level of ALP activity than that in the control group (P<0.05). CGF stimulated the expression of the genes associated with osteogenesis, such as Col-I and Runx2. Conclusion: CGF can promote the proliferation and osteogenic differentiation in ADSCs in vitro.
