Fig. 6From: Effects of annulus defects and implantation of poly(lactic-co-glycolic acid) (PLGA)/fibrin gel scaffolds on nerves ingrowth in a rabbit model of annular injury disc degenerationmRNA expression of aggrecan, Col1A1, Col2A1, and MMP-3 at 6 months after surgery. There was a marked reduction of aggrecan and Col2A1 and a significant increase of Col1A1 and MMP-3 expression in the injured discs, compared with those in the control group. The mRNA expression in the PLGA/fibrin gel implantation group was comparable to that in the control group (P > 0.05).
