Cytotoxicity analysis and RPR of BMSCs on scaffolds. Cytotoxicity analysis of BMSCs survived in material leaching liquor using MTT assay; n = 3 (A). RPRs of BMSCs growing on PLGA and nHA coated PLGA scaffolds after 3, 5, and 7 days in vitro (B).
Notes: *P < 0.05 and **P < 0.01 compared to the other group, n = 6.
Abbreviations: BMSC, bone marrow stromal cells; MTT, 3-(4, 5-dimethylthiazoyl- 2-yl)-2, 5-diphenyltertrazolium bromide; nHA, nano-hydroxyapatite; PLGA, poly (lactic-co-glycolic acid); RPR, relative proliferation ratio.
