Chondrogenic differentiation potential. (a) Chondrogenic differentiation after 21 days of culture in chondrogenic induction medium containing either HS, D1, D5, D10 serum, FCS, or serum-free (positive control). Images were taken at a magnification of 40x. Glycosaminoglycan content is depicted in orange. Demarcation of areas not stained positively for glycosaminoglycans in black using visual analysis software (based on OpenCV library version 4.1.0). Standard parameters were used in the analysis of each image. (b) Quantitative analysis of the glycosaminoglycan content of the chondrogenic pellet showed no significant differences between different groups (, , ).
