Abstract

Articular cartilage is an avascular and aneural tissue lacking lymph drainage, hence its inability of spontaneous repair following injury. Thus, it offers an interesting model for scientific research. A number of methods have been suggested to enhance cartilage repair, but none has yet produced significant success. The possible application of the aforementioned methods has brought about the necessity to evaluate their results. The objective of this study was to analyze results of a study of the effects of the use of TGF-beta gene transduced bone marrow clot on articular cartilage defects using ICRS visual histological assessment scale. The research was conducted on 28 skeletally mature sheep that were randomly assigned to four groups and surgically inflicted femoral chondral defects. The articular surfaces were then treated with TGF-beta1 gene transduced bone marrow clot (TGF group), GFP transduced bone marrow clot (GFP group), untransduced bone marrow clot (BM group) or left untreated (NC group). The analysis was performed by visual examination of cartilage samples and results were obtained using ICRS visual histological assessment scale. The results were subsequently subjected to statistical assessment using Kruskal-Wallis an...Continue Reading

Allogenic & Autologous Therapies

Allogenic therapies are generated in large batches from unrelated donor tissues such as bone marrow. In contrast, autologous therapies are manufactures as a single lot from the patient being treated. Here is the latest research on allogenic and autologous therapies.

Blood Clotting Disorders

Thrombophilia includes conditions with increased tendency for excessive blood clotting. Blood clotting occurs when the body has insufficient amounts of specialized proteins that make blood clot and stop bleeding. Here is the latest research on blood clotting disorders.
