  • EFFECT OF PLATELET DERIVED GROWTH FACTOR BB ON HEALING OF MEDIAL COLLATERAL LIGAMENT IN RATS

    Objective To examine an effect of the locally-used platelet derived growth factor-BB (PDGF-BB) on the healing of the medial collateral ligament (MCL) in the knee joints of rats. Methods Forty-eight rats were equally randomly divided into 2 groups: the experimental group (group A) and the control group(group B). MCL of all the rats were ruptured to establish the wound models. In group A, 5 μg of PDGF-BB was locally injected in the wound of each rat and then the wound was sutured; but in group B, the wound was only sutured. After 2 weeks, histological evaluations were performed to determine whether PDGF-BB could promote the healing of MCL. Results There were significantly more fibroblasts formed during the ligament healing process in group A than in group B (213.44±15.32 vs. 180.42±12.78, Plt;0.01). The fibroblasts were more mature andmore regularlyarranged in group A than in group B. The type, content, and crosslink of the collagen were improved to a greater extent in group A than in group B (Plt;0.01). Conclusion PDGF can promote the healing of the injured ligament.
