Additional file 3 of IGF-1C domain–modified hydrogel enhanced the efficacy of stem cells in the treatment of AMI

Additional file 3: Figure S1. Characterization of CS-IGF-1C hydrogel and anti-apoptotic in NMVCs. (A) IGF-1C was grafted onto CS by a click reaction between the azide of IGF-1C-N3 and the alkyne of alkynyl-CS. (B) The thermosensitive CS-IGF-1C hydrogel neutralized with β-GP were liquid at 4 °C and cross-linked into hydrogel at 37 °C. (C) The protective effects of CS-IGF-1C hydrogel and hP-MSCs co-transplantation on NMVCs.
