What researchers are saying...
“Commercially available mini-osmotic pumps were pre-tested in vitro and proved to be a reliable method of slowly releasing the protein that was biologically active... The continuous presence of BMP-7 during the 2-4 weeks following surgery seemed to have attracted surrounding mesenchymal-like cells from the synovium into the defect area, and then transformed into chondrocytes.” Pecina et al. International Orthopaedics 2002; 26:131-136.
