Figure Lengend Snippet: Kidney mesenchymal cells expand after CA/CPR. (A) Representative flow cytometry plots of PDGFRβ+ mesenchymal cells in the kidney after CA/CPR. Plots shown are gated on live, single cells. (B) Quantification of (A). (C) Representative flow cytometry plots of CD45+PDGFRβ+ mesenchymal cells in the kidney at different time points after CA/CPR. (D) Quantification of (C). (E) Representative 20× immunofluorescence images of PDGFRα/β staining at different time points after CA/CPR. (F) Representative 20× immunofluorescence images of αSMA staining at different time points after CA/CPR. (G) Quantification of (F). (H) qRT-PCR for Acta2 (codes for αSMA) and Col1a1 (codes for type 1 collage) in the kidney at 49 days after CA/CPR compared with sham. *P < 0.05, ***P < 0.001 compared with sham in one-way ANOVA. n=4–8/group. Scale bars=100 μm. CA/CPR, cardiac arrest/cardiopulmonary resuscitation; #αSMA+, number of αSMA positive cells per high-powered field; αSMA, α smooth muscle actin; PDGFRα/β, platelet-derived growth factor α and β.

Figure Lengend Snippet: Immune cells colocalize with mesenchymal cells during AKI-CKD transition. Representative 40× immunofluorescence images of different time points after CA/CPR, including 3 days (A), 7 days (B), and 49 days (C). CD45 used to label immune cells, and PDGFRα/β used to label mesenchymal cells. Scale bar=100 μm.

Figure Lengend Snippet: Inflammatory cell infiltration in corneal and conjunctival tissues in the control group and PM-treated groups. ( A ) Representative images for CD45 immunofluorescent staining of the corneal, limbus, and conjunctival epithelium/stroma on day 14. Scale bar: 100 µm. There was almost no infiltration of CD45-positive cells in the central corneal tissues of the control group and the PM-treated groups, whereas a few positive cells were found in the limbus, and the numbers in the PM-treated groups increased significantly. Compared with the control group, a significantly increase in CD45-positive cells was observed in the conjunctiva of the PM-treated groups after 14 days of treatment ( B ). Each value represents the mean ± SD, n = 5. * P < 0.05 PM-high versus control, # P < 0.05 PM-high versus PM-low, v P < 0.05 PM-low versus control.
