“…NPCs injected systemically into healthy animals were in fact never found in the CNS, while exclusively accumulating (and persisting only for a short period) in peripheral organs (Pluchino et al, 2003). Specific homing of transplanted NPCs has been shown, so far, in experimental brain stroke (Chu et al, 2003;Lindvall and Kokaia, 2011), SCI (Takeuchi et al, 2007), epilepsy (Chu et al, 2004;Hattiangady et al, 2008), HD (Lee et al, 2006), and glioblastoma (Aboody et al, 2000;Ahmed et al, 2011).…”
