Different Compositions of Tested Hydrogels

(A) Hydrogels were Prepared by Combining Varying Concentrations of Thiolated Hyaluronic Acid and Gelin in Water at the Final Concentrations of (40:60), (50:50), or (60:40)%, Respectively: the Extralinker Polyethylene Glycol Diacrylate was then Added to the Mixtures at Volume Ratios 1:4, 1:6, or 1:8
Conditions
HA and gelin concentration (%)	HA: gelin (40:60)	HA: gelin (50:50)	HA: gelin (60:40)
Extralinker (PEGDA): HA and gelin mix (v/v)	r 1:4 r 1:6 r 1:8

(B) Nine Hydrogel Formulations Obtained Based on Combination of Different Extralinker Concentrations (1:4, 1:6, or 1:8) and Different Hyaluronic Acid:Gelin Concentration
	r [Extralinker (PEGDA): HA and gelin mix] (v/v)
	1:4	1:6	1:8
HA and gelin concentration (%)
HA: gelin (40:60)	HA: gelin (40:60), r 1:4	HA: gelin (40:60), r 1:6	HA: gelin (40:60), r 1:8
HA: gelin (50:50)	HA: gelin (50:50), r 1:4	HA: gelin (50:50), r 1:6	HA: gelin (50:50), r 1:8
HA: gelin (60:40)	HA: gelin (60:40), r 1:4	HA: gelin (60:40), r 1:6	HA: gelin (60:40), r 1:8

Here, r: designated extralinker ratio.

PEGDA, polyethylene glycol diacrylate; HA, hyaluronic acid.
