Figure Lengend Snippet: Growth curves for scaffolds made from PEUU (C0/ 1080) and PEUU with 10% collagen (C10/1080) seeded with umbilical artery smooth muscle cells and cultured for up to 28 days. The relative cell number is based upon MTT absorption and reflects mitochondrial activity.

Article Snippet: Scaffolds were cut and sterilized by immersion in 70% ethanol for 6 h, followed by rinsing with PBS and exposure to the ultraviolet light source in a laminar flow hood (Class II A/B3 Biological Safety Cabinet) for 2 h. Scaffolds were placed in a centrifuge tube with human umbilical artery smooth muscle cells (UASMCs, Bio Whittaker) at a density of 1 × 10 6 cells/ml in medium (SmGM-2 with 10% fetal bovine serum, BioWhittaker).

Article Title: Enhanced serelaxin signalling in co‐cultures of human primary endothelial and smooth muscle cells

doi: 10.1111/bph.13371

Figure Lengend Snippet: cGMP accumulation in co‐cultures of human primary vascular smooth muscle cells following addition of serelaxin to endothelium. HUAEC , HUVEC or HCAEC were co‐cultured with (A) HUASMC or (B) HUVSMC (all n = 5), and the ECs were treated with serelaxin for 30 min. Serelaxin addition to HUAEC did not cause cGMP accumulation in HUAEC (▲) (C) HUASMC (□) or (D) HUVSMC (◯) co‐cultured with HUAEC, whereas direct stimulation of either (C) HUASMC (n = 5) or (D) HUVSMC with serelaxin caused a concentration‐dependent increase in cGMP accumulation (dashed lines). In contrast, serelaxin addition to HUVEC concentration‐dependently increased cGMP accumulation not only in HUVEC (■) but also in (E) HUASMC (□) or (F) HUVSMC (◯) co‐cultured with HUVEC with the responses in smooth muscle cells being greater or in the case of HUVSMC much greater than cGMP responses to direct stimulation of (E) HUASMC or (F) HUVSMC (dashed lines). A similar pattern of cGMP accumulation was observed with (G, H) HCAEC (●) and (G) HUASMC (□) or (H) HUVSMC (◯) co‐cultured with HCAEC.

Figure Lengend Snippet: Serelaxin‐mediated cGMP accumulation in monocultures of human primary vascular cells (all n = 5). Serelaxin (30 nM, 30 min) increased cGMP accumulation in (A) HUVEC, (B) HCAEC, (C) HUASMC and (D) HUVSMC. Pre‐incubation with l‐NOARG (30 μM, 30 min) or ODQ (1 μM, 30 min) almost abolished serelaxin‐mediated (30 nM, 30 min) cGMP accumulation in all cell types. Pre‐treatment with indomethacin (30 μM, 30 min) significantly inhibited serelaxin‐mediated (30 nM, 30 min) cGMP accumulation in (B) HCAEC but had no effect in (A) HUVEC, (C) HUASMC or (D) HUVSMC. *P < 0.05, **P < 0.02, ***P < 0.005; significantly different from serelaxin alone; one‐way anova with Dunnett's post hoc test.

Figure Lengend Snippet: Serelaxin‐mediated cGMP accumulation in human primary vascular smooth muscle cells co‐cultured with HUVEC or (A) HCAEC (all n = 6 except where otherwise indicated). Stimulation of HUVEC or HCAEC with serelaxin (30 nM, 30 min) increased cGMP accumulation not only in (B) HUVEC and (C) HCAEC but also in co‐cultures of (D, F) HUASMC or (E, G) HUVSMC. Pre‐incubation of HUVEC or HCAEC with l‐NOARG (30 μM, 30 min) before addition of serelaxin (30 nM, 30 min) significantly inhibited cGMP accumulation not only in HUVEC and (C) HCAEC but also in (D, F) HUASMC and (E, G) HUVSMC. Pre‐incubation of HUVEC with indomethacin (30 μM, 30 min) did not affect serelaxin‐mediated (30 nM, 30 min) cGMP accumulation in (B) HUVEC or in co‐incubated (D) HUASMC or (E) HUVSMC (n = 5). Pre‐incubation of HCAEC with indomethacin (30 μM, 30 min) had no significant effect on serelaxin‐mediated (30 nM, 30 min) cGMP accumulation in (C) HCAEC but produced marked and significant reductions in cGMP accumulation in co‐incubated (F) HUASMC or (G) HUVSMC (n = 5). Pre‐treatment of HUASMC or HUVSMC with ODQ (1 μM, 30 min) had no significant effect on serelaxin‐mediated (30 nM, 30 min) cGMP accumulation in (I) HUVEC or (J) HCAEC but reduced or abolished cGMP accumulation in (K, M) HUASMC or (L, N) HUVSMC (n = 5). *P < 0.05, **P < 0.02, ***P < 0.005 significantly different from serelaxin alone; one‐way anova with Dunnett's post hoc test.

Figure Lengend Snippet: cAMP accumulation in co‐cultures of human primary vascular smooth muscle cells following addition of serelaxin to endothelium (all n = 5). HUAEC, HUVEC or HCAEC were co‐cultured with (A) HUASMC or (B) HUVSMC, and the endothelial cells were treated with serelaxin for 30 min. Serelaxin added to HUAEC did not cause cAMP accumulation either in (C, D) HUAEC (▲), (C) HUASMC (□) or (D) HUVSMC (◯), whereas direct stimulation of (C) HUASMC or (D) HUVSMC with serelaxin caused a concentration‐dependent increase in cAMP accumulation (dashed lines). Although direct addition of serelaxin to HUVEC concentration‐dependently increased cAMP accumulation in (E, F) HUVEC (■), there was no significant effect on cAMP accumulation in (E) HUASMC (□) or (F) HUVSMC (◯). Direct addition of serelaxin to (E) HUASMC or (F) HUVSMC stimulated cAMP accumulation (dashed lines). Serelaxin concentration‐dependently increased cAMP accumulation in (G, H) HCAEC (●) but also caused a robust concentration‐dependent increase in cAMP accumulation in both (G) HUASMC (□) and (H) HUVSMC (◯).

Figure Lengend Snippet: Serelaxin‐mediated cAMP accumulation in human primary vascular smooth muscle cells co‐cultured with HCAEC (A, E; all n = 5). Stimulation of HCAEC with serelaxin (30 nM, 30 min) increased cAMP accumulation not only in (B) HCAEC but also in co‐cultures of (C) HUASMC or (D) HUVSMC. Pre‐incubation of HCAEC with l‐NOARG (30 μM, 30 min) before addition of serelaxin (30 nM, 30 min) had no significant effect on cAMP accumulation in (B) HCAEC, (C) HUASMC or (D) HUVSMC. However, pre‐incubation of HCAEC with indomethacin (30 μM, 30 min) significantly inhibited serelaxin‐mediated (30 nM, 30 min) cAMP accumulation in (B) HCAEC and abolished cAMP accumulation in (C) HUASMC or (D) HUVSMC.

Figure Lengend Snippet: Signal transduction mechanisms activated by serelaxin in co‐cultures of human primary vascular cells. Activation of RXFP1 by serelaxin in HUVEC and HCAEC stimulates NO production and activates sGC and AC to produce cGMP and cAMP respectively. Endothelial NO also diffuses from the endothelial cells across the ThinCert membranes and activates sGC in both the arterial and venous smooth muscle cells. Additionally in HCAEC (blue lines) but not HUVEC, serelaxin stimulates prostanoid production that produces cAMP accumulation in both arterial and smooth muscle cells.
