Antioxidant effects of betulin on porcine chondrocyte behavior in gelatin/C6S/C4S/HA modified tricopolymer scaffold
چکیده انگلیسی
The antioxidant effects of betulin on porcine chondrocytes cultured in gelatin/C6S/C4S/HA modified tricopolymer scaffold for a period of 4 weeks was investigated. The porous structure of the scaffold and cell attachment was observed by scanning electron microscopy (SEM). Biochemical measures of necrosis, cell proliferation, sulfated glycosaminoglycans (sGAG) content and extracellular matrix related gene expressions were quantitatively evaluated. The cell proliferation data showed good cellular viability in tricopolymer scaffold and increased optical density for total DNA demonstrated that the cells continued to proliferate inside the scaffold. The sGAG production indicated chondrogenic differentiation. Chondrocytes treated with betulin expressed transcripts encoding type II collagen, aggrecan, and decorin. To conclude, the substantiated results supported cell proliferation, production of extracellular matrix proteins and down-regulation of matrix metalloproteases and cytokine, in betulin treated scaffolds.
