Figure 1From: Hyaluronic acid affects the in vitro induction effects of Synthetic PAMPS and PDMAAm hydrogels on chondrogenic differentiation of ATDC5 cells, depending on the level of concentration Histological observations of the ATDC5 cells cultured for 7 days, using phase contrast microscopy (each scale bar shows 100 micrometer). A: Culture on polystyrene (PS) in the maintenance medium (without insulin); B: Culture on PS in the differentiation medium (with insulin); C: Culture on PAMPS gel in the maintenance medium; D: Culture on PDMAAm gel in the maintenance medium.Back to article page
