Abstract:
ObjectiveTo investigate the effect of basic fibroblast growth factor-polyactide release nanospheres on proliferation and adipogenic induction of adipose-derived stem cells in vitro.MethodsAdipose-derived stem cells were isolated and induced for three-line differentiation in vitro.The culture medium and inductive medium of stem cells were prepared containing 0,1,2,3,4 and 5 mg/ml basic fibroblast growth factor-polyactide release nanospheres,respectively.Adipose-derived stem cells were cultured ina 96-well plate and replaced the culture medium containing release nanospheres the second day.The cells proliferation was detected by the method of MTT every day and quanti fication of oil red O every other day.The data obtained were analyzed with SPSS13.0 statistical software.ResultsThe basic fibroblast growth factor polyactide release nanospheres had the ability promoting proliferation and adipogenic induction of adipose-derived stem cells.The best concentration of nanospheres was 3 mg/ml and 4 mg/ml,respectively.ConclusionsThe basic fibroblast growth factor-polyactide release nanospheres could promote proliferation and adipogenic induetionof adipose-derived stem cells significantly.It could be used as an ideal cytokine release nanospheres in adipose tissue engineering.
