Figure 2: Quantitative analysis of BrdU-labeled cells in the ependymal and parenchymal regions. (a) Result of immunohistochemistry using anti-BrdU antibody. (b) Enlargement of the boxed region in (a), showing BrdU-labeled cells in the parenchymal region. (c) Average number of BrdU-labeled cells per white matter area from all five white matter areas in the parenchymal region. (d) Average number of BrdU-labeled cells per ependymal region in grey matter. At 14 days after transplantation, proliferation of endogenous cells was significantly increased from injury site to cell transplantation site in hUCB-MSCs-transplanted group compared with control group, .
