Figure Lengend Snippet: Plasma coagulation factor assays of WT and PC+/− mice after CLP surgery. a: Plasma PC levels. The plasma PC levels were determined by ELISA before (WT, n = 4; PC+/−, n = 5), and 6 hours (WT, n = 5; PC+/−, n = 7) and 24 hours (WT, n = 5; PC+/−, n = 5) after CLP surgery in WT and PC+/− male mice. *, P < 0.001; #, P < 0.01. b: Plasma fibrinogen levels were determined by a coagulometric assay at 6 hours (WT, n = 4; PC+/−, n = 5) and 24 hours (WT, n = 15; PC+/−, n = 14) after, CLP surgery and in resting (WT, n = 11; PC+/−, n = 9) WT and PC+/− male mice. *, P = 0.016. c: Plasma PAI-1 levels were determined by ELISA before (WT, n = 3; PC+/−, n = 4), and 6 hours (WT, n = 3; PC+/−, n = 7) and 24 hours (WT, n = 5; PC+/−, n = 4) after, CLP surgery in WT and PC+/− male mice. d: Plasma FXII levels relative to the resting WT group, as measured by a coagulometric assay, before (WT, n = 4; PC+/−, n = 3) and 24 hours after (WT, n = 5; PC+/−, n = 3), CLP surgery. *, P = 0.05 (Kruskal-Wallis). e: Plasma FXI levels relative to the resting WT group as measured by a coagulometric assay, before (WT, n = 7; PC+/−, n = 5) and 24 hours after (WT, n = 5; PC+/−, n = 3), CLP surgery. No significant differences were observed.

Figure Lengend Snippet: Gene expression ratio to RPL-19 of PAI-1 (a), MPO (b), IL-1β (c), and IL-6 (d) relative to the WT resting group (n = 3) in liver, kidney, and lung, as determined by RT-PCR in WT mice 24 hours after CLP (n = 3), PC+/− resting mice (n = 3), and PC+/− mice 24 hours after CLP (n = 4). a: In liver, PC+/− mice 24 hours after CLP were different from PC+/− resting and WT resting groups (P = 0.025, K-W), in kidney, differences between groups were not significant (K-W, multicomparison test). b: In liver, PC+/− resting mice were different from PC+/− mice 24 hours after CLP and WT resting groups (P = 0.055); in kidney, PC+/− mice 24 hours after CLP were different from all of the other groups (P = 0.02, K-W); in lung, PC+/− resting mice were different from PC+/− and WT mice 24 hours after CLP (P = 0.08, K-W). c: In liver, no significant differences between groups were found; in kidney: PC+/− group 24 hours after CLP was different from WT and PC+/− resting groups (P = 0.04, K-W); in lung: the PC+/− group after CLP was not different form the PC+/− resting group (T-K); P = not significant (K-W). d: In liver, PC+/− mice 24 hours after CLP were different from the WT resting group (P = 0.11, K-W); in kidney, PC+/− mice 24 hours after CLP were different from the WT and PC+/− resting groups (P = 0.032, K-W); in lung: no significant differences between the groups were found (K-W).

Article Title: Porcine pericardial decellularized matrix bilayer patch containing adipose stem cell-derived exosomes for the treatment of diabetic wounds

doi: 10.1016/j.mtbio.2024.101398

Figure Lengend Snippet: Fig. 10. The exosome-loaded bilayer decellularized pericardial patches promote the healing of diabetic refractory wounds by enhancing the activation of M2 macrophages in the wound and activating the cAMP signaling pathway. (A) On day 7, dual immunofluorescence staining for F4/80 (M0 marker), iNOS (M1 marker), and CD206 (M2 marker) was performed to assess the numbers of activated M1 and M2 macrophages in the wound and surrounding skin tissue, scale bar = 50 μm. (B) On day 7, RT-qPCR was used to detect the expression levels of M1 (cd86, il-6) and M2 (cd163, arg-1) macrophage-related genes in the wound tissue of each group. (C) On day 7, Western Blotting experiments were conducted to measure the expression levels of key proteins in the cAMP signaling pathway (Atp1a2, Calm4, and Cngb1) in the wound tissue of each group, with quantitative analysis of protein density, n = 3 (D). *, p < 0.05, **, p < 0.01, and ***, p < 0.001, compared with the PBS group.
