20110027339 | POROUS IMPLANTS AND STENTS AS CONTROLLED RELEASE DRUG DELIVERY CARRIERS - The common premise of synthetic implants in the restoration of diseased tissues and organs is to use inert and solid materials. Here, a porous titanium implant enables the delivery of microencapsulated bioactive cues. Control-released TGFβ1 promoted the proliferation and migration of human mesenchymal stem cells into porous implants in vitro. Upon 4-wk implantation in the rabbit humerus, control-released TGFβ1 from porous implants significantly increased BIC by 96% and bone ingrowth by 50% over placebos. Control-released 100 ng TGFβ1 induced equivalent BIC and bone ingrowth to adsorbed 1 μg TGFβ1, suggesting that controlled release is effective at 10-fold less drug dose than adsorption. Histomorphometry, SEM and μT showed that control-released TGFβ1 enhanced bone ingrowth in the implant's pores and surface. These findings suggest that solid prostheses can be transformed into porous implants to serve as drug delivery carriers, from which control-released bioactive cues augment host tissue integration. | 02-03-2011 |
