UNASSIGNED: The aim of the present study was to provide a theoretical and experimental foundation on the differentiation of stem cells through the induction of multiple genes. The lentiviral vector carrying @entity14100 and @entity17662 genes was transfected to bone marrow-derived mesenchymal stem cells (BMSCs) which differentiated into chondrogenesis. Healthy New Zealand white @entity95 , 2-3  months of age were used in the present study. A 6-8  ml of bone marrow was isolated from the iliac and tibial shaft of each @entity95 . The BMSCs suspension was aspired following centrifugation of the bone marrow by percoll separating medium. The BMSCs were primarily cultured and subcultured in  vitro, then divided into four groups according to the difference of lentivirus vectors: group  A, receiving transforming growth factor b1 ( @entity14100 ); group  B, receiving @entity14100 and @entity17662 ( @entity17662 ); group  C, empty vector transfection; and group  D, receiving no cell growth factor. Fluorescence expression was detected 12  h after transfecting the lentiviral vector carrying the @entity14100 and @entity17662 gene to BMSCs. The transfection efficiency was approximately 70% with a MOI=100 after 96  h. Expression of @entity39901 aggrecan and Type      collagen in groups  A-E on day  7 and 14 was detected by RT-PCR and western blot analysis. The expression level of three genes expressed in groups  A and C were higher compared to the expression in groups  B, D and E. The expression level of the three genes expressed in group  B was higher compared to the expression in group  D. The expression level of three genes expressed in group  A and C showed no statistical difference. Cytokines therefore play an important role in cell proliferation and chondrogenic differentiation. @entity14100 has a synergistic effect in the differentiation. In addition, @entity17662 may have a protective role in the restoration of cartilaginous tissue.

Lentiviral-mediated multiple gene transfer to chondrocytes promotes chondrocyte differentiation and bone formation in XXXX bone marrow-derived mesenchymal stem cells.
