Determination of cell viability. During the exponential growth phase, bMSCs were infected with either the Lv-Control or Lv-BMP-2 at an MOI = 20 and seeded into 96-well plates at 1 × 10⁵/well 72 h later, followed by incubation under normal culture conditions. The MTT assay was performed as described in the Materials and Methods. The absorbance (A) at 490 nm was determined to estimate changes in cell viability. * p < 0.05 vs. bMSCs and ** p < 0.01 vs. bMSCs.
