TSPO and central nervous system cancer: It is likely that these results reflect a similar pattern to the TSPO expression of glioma‐associated microglia/macrophages (GAMs).13, 44, 45 A previous report demonstrated that GAMs contributed to the uptake in glioma PET imaging with the TSPO radioligand, but their influence on glioma TSPO expression was weak.46 Together, these results suggested that the detected signal by PET with [18F] FEDAC would be predominantly derived from Nestin+ undifferentiated neural cells after hiPSC‐NS/PCs transplantation, and not microglia nor astrocytes associated with neuroinflammation.
