Background :Gelatin and chitosan are known as biodegradable and biocompatible biopolymers.These biopolymers have recently receivedincreasingly more attention for tissueengineering.The aim of this study was to evaluate the toxicity effects of gelatin-chitosan film on bone marrow stromal cell(BMSCs) culture in rat.                                                  Materials & Methods: First, gelatin- chitosan composites film were prepared by solution mixing, followed by film casting of both biopolymers in glacial acetic acid.After two passage of BMSCs culture, the cells were cultured in four plate groups including: control plates have no any film,gelatinplates,chitosan plates and gelatin- chitosan plates.Theproliferation,differentiation,viability and apoptosis rates of BMSCs were studied duringthesecond,fourthand sixth days.The activity of superoxidedismutase(SOD),catalase(CAT)and  glutathione(GSH) and malondialdehyde(MDA) levels were determined by using biochemical methods. Results:The results showed that the mean BMSCs proliferation significantly reduced in chitosan group compared to control group (p
