Figure 1. Characterization of HA-blood (human, lysed) and HA-PEG hydrogels.

Figure 1

A. Scanning electron microscopy image of CDC encapsulated in HA-blood hydrogel. (Calibration bar is 40μm).

B. Gelation time of HA-PEG and HA blood hydrogels was similar but equilibrium swelling ratio of HA-PEG hydrogels was greater than HA-blood hydrogels

C. Young’s moduli of HA-blood hydrogels using human blood was higher than the modulus of rat myocardium and HA-blood hydrogels composed of lysed rat blood (WK rats)

D. Young’s moduli of HA-blood hydrogels decreased proportionately as the concentration of lysed blood in the hydrogels decreased by diluting with PBS

E. Minimal degradation of HA-blood and HA-PEG hydrogels by hydrolysis (dashed lines). Presence of CDCs accelerates degradation of HA-blood hydrogels (solid lines).

F. Protein release from HA-blood hydrogels in PBS
