Development of an Electroactive Hydrogel as a Scaffold for Excitable Tissues

Viability and proliferation of seeded MSCs. (a) Percent viability of MSCs cultured on 10 kDa PEGDA-PAA hydrogels as they proliferated over time. (b) Viability of MSCs after 24 hours of culture, with and without stimulation with the voltage required to effect actuation for 10 kDa (20 V) and 20 kDa (5 V) hydrogels. Note: following stimulation, 10 kDa hydrogels had zero cell viability. Error bars indicate standard deviation (n = 9). Asterisks indicate the difference of 20 kDa groups compared to 10 kDa groups.
