Additional file 4: of Blockade of TGF-β/Smad signaling by the small compound HPH-15 ameliorates experimental skin fibrosis

Figure S4. The inverse proportional change of Ly6Chi macrophages and CD206+ M2 macrophages from the inflammation stage (day 7) to the fibrotic stage (day 21). The single-cell suspension obtained from the back skin of bleomycin-injected C57BL/6 mice on day 7 and day 21 was stained with the mAbs against CD45, CD11b, Ly6C, and CD206. Stained samples were analyzed using the FACSCanto II system. Data were analyzed using FlowJo software version 7. All values represent mean ± SEM. n = 3 at each time point. ** p ≤ 0.01. (PDF 49 kb)
