Morphologic changes in mesenchymal stem cells (MSCs) after transduction by recombinant lentiviruses that expressed human nerve growth factor (hNGF). Magnification ×40 showed the appearance of membrane extremities in NGF overexpressed cells at 24 and 48 hours after transduction. A. Non-Transdicted, B. 24 hours, and C. 48 hours post transduction.
