FIG. 2.

Morphology of keratinocytes differentiated from ADMSCs. (A) Representative light micrograph of a field from DM-control; (B) Micrograph from TN showing epithelial polarity maintained by cells, which was evident by the convex shape of cells and tight cellular junctions; (C) Micrograph of a larger field of test culture showing more colonies of keratinocyte-like cell islands. (D) Larger cells formed during extended days of culture in test niche. A, B, and D, scale bar=100 μm. C, scale bar=200μm.
