abstract ={There are numerous strategies under development to supplement or replace bone grafts. Among these synthetic options, growth factors such as bone morphogenetic protein (BMP-2) are often used. However, current burst delivery strategies have been associated with a number of complications. Transplanting cells engineered to over-express osteoinductive proteins over a longer period of time is a possible solution to this problem. In this study, we demonstrated the use of a parainfluenza virus 5 (PIV-5) vector (amplifying virus-like particles, AVLP) to induce expression of exogenous proteins in mesenchymal stem cells (MSC). We obtained extended expression of enhanced green fluorescent protein eGFP in transduced MSCs, as well as selection and maintenance of eGFP+ cells. We also attained expression of BMP-2 on a shorter timescale using this method. We conclude that AVLP is a promising tool for genetic engineering, both in regenerative medicine and other applications.}
