Figure 1 Characterization of cultured fibroblasts by FSP-1. Cultured GF (A), PLF (B), PDPF (C), and DDPF (D) were immunostained for FSP-1. Images captured by a confocal microscope (representative bars, 20 μm).

Figure 2 Production of CCL3 (MIP-1α) by cultured fibroblasts. Cultured GF, PLF, PDPF, and DDPF were stimulated with EcLPS (A–C) and EfLTA (D–F) at the indicated concentrations. Cell supernatants were collected after 1 hour (A and D), 6 hours (B and E), and 24 hours (C and F). Production of CCL3 was detected by ELISA. *P < .05, **P < .01, and ***P < .001 in comparison with culture medium alone (0). Significant differences with #GF, with %PLF, and with &PDPF (n = 6).

Figure 3 Production of CXCL12 (SDF-1) and expression of miR-141 and miR-200a by cultured fibroblasts. Cultured GF, PLF, PDPF, and DDPF were stimulated with EcLPS (A–C) and EfLTA (D–F) at the indicated concentrations. Cell supernatants were collected after 1 hour (A and D), 6 hours (B and E), and 24 hours (C and F). Production of CXCL12 was detected by ELISA. *P < .05, **P < .01, and ***P < .001 in comparison with culture medium alone (0). Significant differences with #GF, with %PLF, and with &PDPF (n = 6). Expression of miR-141 (G) and miR-200a (H) was detected by means of qPCR for EcLPS-stimulated cells for 24 hours (n = 6).
