Detection of in vivo survival of neuronal progenitor cell by BLI (a). BLI of representative animals transplanted with 1×10⁵ neuronal progenitor cell (ReNcells) with or without helper cells into Rag^2−/− immunodeficient mice show strong BLI signal on the same day after transplantation, which decreases progressively over the following days. b Quantification of BLI signal for each group (n =5 each), with the intensity expressed as photon/s/cm²/sr. c Estimation of percent donor cell survival plotted as % signal activity (normalized to day 0) over the 5-day period following transplantation.
