Fig. 1From: Atomic Force Microscopy-Based Nanoscopy of Chondrogenically Differentiating Human Adipose-Derived Stem Cells: Nanostructure and Integrin β1 ExpressionCharacteristics of hADSc morphology during chondrogenesis. a Morphological images of whole hADSc were obtained at 0, 6, and 12 days of chondrogenic differentiation. Images were analyzed by a Height and Peak Force Error Image Model by Nanoscope. b The average length/width ratio of cells was measured following chondrogenic differentiation treatment at 0, 6, and 12 days. *p < 0.05, **p < 0.01Back to article page
