Figure 4. Human mesenchymal stem cells mediated host cell proliferation.
Representative immunofluorescence confocal images illustrate endogenous Ki67+ cells spread within the hMSC injection area at day 3. Human mesenchymal cells contain red fluorescent mCherry protein. Ki67+ cells were rarely seen in the gastrocnemius muscles of ischaemic legs of vehicle- and ILO-treated mice. Scale bar, 25 μm.
