RESULTS: The microscopic observation showed chondrocytes in the transducted group proliferated stably, and triangle, and spindle cells were predominant in the seventh passage, accompanied by few long-spindle and root cells. In addition, the cells were of clear appearance and large lucency. However, in the non-transducted group, long-spindle cells were observed in the fourth passage, and almost all cells exhibited long-spindle shape in the fifth passage.
