Representation of the total number of proliferative cells at 1 week and 4 weeks post-transplantation.

<p>Total numbers of Ki67+ (A), Ki67+/Dcx+ (B) and Ki67+/CD11b+ (C) cells per mm³ in the striatum are shown for MCAO/NAC and MCAO/cells groups, one week and four weeks post-transplantation. A) In the absence of cells, the number of proliferative cells in the striatum decreased dramatically between the two time-points (grey volume). In the presence of CTX0E03, the number of Ki67 cells in the striatum decreased more slowly (white volume). B) As for the total number of Ki67+ cells, the numbers of proliferating neuroblasts was maintained by the presence of CTX0E03 (white) as compared to the loss observed in NAC-injected animals (grey). C) Only few microglial cells proliferate at the two time points observed (grey), whereas CTX0E03 cells lead to increased microglial proliferation (white) that decreases with time.
