Experimental Groups for Scaffold Fabrication with Varied T3-Loaded Chitosan NPs Content

Sample	Condition
PG	Cells were cultured on PCL/gelatin scaffold without PAG and without chitosan NPs.
PG/PAG 2	Cells were cultured on PCL/gelatin scaffold containing 2% PAG and without chitosan NPs.
PG/PAG 2/1% NPs	Cells were cultured on PCL/gelatin scaffold containing 2% PAG and 1% T3-loaded chitosan NPs.
PG/PAG 2/2% NPs	Cells were cultured on PCL/gelatin scaffold containing 2% PAG and 2% T3-loaded chitosan NPs.
PG/PAG 2/3% NPs	Cells were cultured on PCL/gelatin scaffold containing 2% PAG and 3% T3-loaded chitosan NPs.

Notes: All above samples were cultured in DMEM/F12 base medium containing 10 ng.mL⁻¹ bFGF, 5 ng.mL⁻¹ PDGF-AA and 200 ng.mL⁻¹ heregulin.
