Abstract
The goal of this research project was to prepare gelatin/PVA porous scaffolds by chemical and gamma irradiation methods to be used for human dermal fibroblast cell culture. First, the polymers were dissolved in hot water and mixed properly to achieve a homogenous solution. The mixture was then frozen at -200C and immersed in ethanol/ glutaraldehyde solution at -200C for 48 hours in order to extract ice crystals and also form chemical crosslinks in gelatin by glutaraldehyde. After being rinsed with distilled water the samples were lyophilized. The effects of polymers solution concentration, gelatin/PVA ratio and glutaraldehyde /gelatin ratio were investigated on characteristics of the...
