Amniotic membrane mesenchymal stromal cell-derived secretome in the treatment of acute ischemic stroke: A case report

Figure 4 Fluorescence activated cell sorting results of circulating regulatory T cells before and after mesenchymal stromal cell-secretome treatments. A: Fluorescence activated cell sorting gating strategy to detect regulatory T cells in peripheral blood; B: Circulating regulatory T cells were identified from the circulating CD4⁺ T cell population as CD4⁺CD25⁺127^low/- using the gating strategy shown. FSC: Forward scatter; SSC: Side scatter; V: Follow-up visit.
