A traumatic brain injury model for distinguishing between transplanted neural cells and host cells in vivo

  • To perform electrophysiological recording and other investigations on transplanted neural cells in vivo, we used mechanical damage to establish a special traumatic brain injury model that could distinguish transplanted cells from host cells. The morphology of the trauma-induced holes in the cortex of the rat brain was regular. The model was stable and repeatable. Neural stem cells were transplanted into the trauma-induced hole, and were able to survive for a long time. Most of the transplanted cells differentiated into neurons, and only a small amount turned into glia cells. There was a clear boundary between the host cells and the transplanted cells. Single cell electrophysiological recording on transplanted neural cells were detected in vivo. This study established a stable and repeatable traumatic brain injury model, which could be used to conduct in vivo electrophysiological recording research on transplanted neural cells.
