Ex vivo autoradiography showing the selective uptake of [¹⁸F] FEDAC in the 253G1‐NS/PCs grafted mouse brains. A, Representative ex vivo autoradiographs of the [¹⁸F] FEDAC on the 253G1‐NS/PCs‐, 414C2‐NS/PCs‐, U‐251MG‐, or PBS‐grafted mouse brain sections. Arrows indicate the transplant site. B, The uptake ratios of radioactivity between ipsilateral and contralateral sides of each mouse brain were calculated as ICRs. Bar graph showing the ICR of the 253G1, 414C2, U‐251MG, and PBS groups. Values are mean ± SD (n = 5, 4, 5, and 4, respectively). *P < .05, **P < .01, ***P < .001. ICR, ipsilateral‐to‐contralateral ratio; NS/PCs, neural stem/progenitor cells; PBS, phosphate‐buffered saline
