Morphology and cell size during MSC differentiation. (A) Scanning electron microscope images of MSC differentiated into osteocytes or adipocytes. The cells were left uninduced (i) or induced into either osteocytes (ii) or adipocytes (iii) in their respective induction media for 14 days. Osteocytes attained an angular shape whereas the adipocytes become globular in shape with oil droplet. Representative image is shown. (B) Flow cytometric analysis of cell size by forward scatter measurement in MSC differentiated into either osteocytes or adipocytes. The cells were analysed after day 0, 1, 3, 7, 14 days of induction into osteocytes or adipocytes. Representative histograms are shown.
