Fluorescent imaging of chondrocytes and NIH3T3 on synthesized cryogel matrices. 4'-6-Diamidino-2-phenylindole (DAPI) image of proliferating chondrocytes on (A) poly(hydroxyethyl methacrylate)-gelatin (HG) and propidium iodide (PI) staining on alginate-gelatin (AG) cryogel (B). Similarly DAPI staining of NIH3T3 fibroblast is shown on both the cryogel matrix of poly(hydroxyethyl methacrylate)-gelatin (HG) (C) and alginate-gelatin (AG) (D).
