Fig. 3: GFP immunostaining with 3,3′-diaminobenzidine (DAB) reveals donor-derived cells within the CNS.

All images at ×20: a, b cells within the cerebellum with the characteristic morphology of Purkinje cells, c occasional cells of a different glial morphology, likely microglia, d cells with an astrocyte morphology, e more prominent within the brainstem are small clusters of undifferentiated donor-derived cells, and f intense GFP staining is also evident within the brain meninges.
