Abstract
Hydroxypropyl chitosan (HPCTS) was crosslinked with gelatin (GEL) and chondroitin sulfate (CS) by 1,4-butanediol diglycidyl ether to synthesize a scaffold. In this study, this scaffold was tested in physical and biological characteristics as a bioactive corneal stroma surrogate. The results showed the scaffold exhibited 83–88% light transmission values at wavelengths of visible light. Besides that, the scaffold had 96% water content and allowed NaCl and glucose to permeate. Moreover, it was suitable for keratocytes growing on its surface. In the biological part, we compared the scaffold with CS-free ones to investigate the potential effect of CS and found out that CS notablely improved cell compatibility of the scaffold.
