For the study, researchers obtained fresh blood and ACL remnants from four patients undergoing ACL reconstruction surgery. Platelet-poor plasma and platelet-rich plasma were prepared from the samples with various growths concentration factors.
Researchers found that the concentration of the main growth factors were higher in the platelet-rich clot than the platelet-poor clot. The in vitro treatment of ACL cells with platelet-rich clot releasate resulted in a significant increase in cell number, and the total collagen production by the platelet-rich clot releasate-treated cells was significantly higher because of the enhanced cell proliferation.
There was no significant effect of the platelet-rich clot releasate treatment on gene expression for type-I collagen. However, type-III collagen was significantly enhanced, according to the report.
