title: Fabrication of chitosan/poly(caprolactone) nanofibrous scaffold for bone and skin tissue engineering.
abstract: Chitosan/poly(caprolactone) (CS/PCL) nanofibrous scaffold was prepared by a single step electrospinning technique. The presence of CS in CS/PCL scaffold aided a significant improvement in the hydrophilicity of the scaffold as confirmed by a decrease in contact angle, which thereby enhanced bioactivity and protein adsorption on the scaffold. The cyto-compatibility of the CS/PCL scaffold was examined using human osteoscarcoma cells (MG63) and found to be non toxic. Moreover, CS/PCL scaffold was found to support the attachment and proliferation of various cell lines such as mouse embryo fibroblasts (NIH3T3), murine aneuploid fibro sarcoma (L929), and MG63 cells. Cell attachment and proliferation was further confirmed by nuclear staining using 4',6-diamidino-2-phenylindole (DAPI). All these results indicate that CS/PCL nanofibrous scaffold would be an excellent system for bone and skin tissue engineering.
