(A) The proliferation of the C2C12 cells on dextran-graft-aniline tetramer-graft-4-formylbenzoic acid and N-carboxyethyl chitosan hydrogels after being released for 1–3 days (* p < 0.05) [82]. (B) The effects of the initial chondrocyte cell number on the cell proliferation of fibrin with calcium ion hydrogels in weeks 2 and 5 [85]. (C) The proliferation of fibroblast from carboxymethyl chitosan and carboxymethyl cellulose dialdehyde hydrogel with and without mesenchymal stem cells (*** p ≤ 0.001, ** p ≤ 0.01, and * p ≤ 0.05) [86]. (D) Blood glucose levels with several methods demonstrate that insulin-loaded injectable silk-fibroin protein hydrogel maintains blood glucose levels the longest [87]. (E) Changes in morphological and metabolic activity of HeLA epithelial cancer cells during release of anti-cancer drug paclitaxel from mucin glycoprotein-based hydrogel (scale bar is 40 μm) [88].
