Figure 5: (a) Photomicrographs of Oil red O staining of MSCs after culture in different ratio of OM and AM for 3, 7, 14, and 21 days. 100/0 indicates the medium containing 100% OM and 0% AM, and so forth. GM indicates the growth medium. Scale bar=500 μm. (b) Percentage of cells that were positively stained with Oil red O after culture in different ratio of OM and AM for 21 days. Data represent mean ± SD (n ≥ 30, n represents the total number of images taken from 3 duplicate wells with more than 10 images from each well).
