Article Title: Three-Layered Silk Fibroin Tubular Scaffold for the Repair and Regeneration of Small Caliber Blood Vessels: From Design to in vivo Pilot Tests

Figure Lengend Snippet: Time dependence of the absolute cell numbers of HAAF (A) , HASMC (B) , and HCAEC (C) cells cultured on SilkGraft and on polystyrene. Absolute cell numbers were lower on SilkGraft than on polystyrene because the available surface area was reduced due to the use of the steel ring which kept the silk substrate under water. Total cell growth differences between cells cultured on SilkGraft or on polystyrene are expressed by the areas under the corresponding curves, the statistical levels of significance of which are: for HAAFs, P < 0.001; for HASMCs, P < 0.01; and for HCAECs, P < 0.001.

Figure Lengend Snippet: Cumulative consumption of glucose and glutamine and release of lactate. Results were normalized per 10 3 cells. (A–C) The cumulative glucose consumption was higher for HAAFs ( P < 0.05) and HCAECs ( P < 0.001) seeded on SilkGraft, whereas it showed only marginal differences between the two substrates for HASMCs ( P > 0.05). (D–F) Glutamine consumption was lower for HAAFs ( P < 0.05) seeded on SilkGraft, similar for HASMCs ( P > 0.05) cultured on the two substrates, and significantly larger for HCAECs ( P < 0.001) grown on the silk substrate. (G,H) The cumulative amount of lactate released by HAAFs and HASMCs was the same whichever the substrate ( P > 0.05). Lactate release could not be assessed for HCAECs because the released lactate was re-uptaken and used for metabolic purposes. The statistical analysis of these data is shown in .

Figure Lengend Snippet: Cultures of EA.hy926 endothelial cells (A) and HCAEC (B, C) were pretreated with TM5441 (10 μM) (A, B) or TM5A15 (10 μM) (C) in triplicate followed by Homocysteine (Hcy) treatment for 4–5 days. Whole cell extracts were prepared and equal amount of pooled proteins from three wells were subjected to Western blot analysis for senescence markers and regulators using specific antibodies as indicated (A–C). Bar represents mean ± sem. Quantitative data are shown on the right (A’-C’). The levels of at least 2–3 senescence markers were determined in repeat experiments. D, E. Whole cell extracts (HCAEC) were prepared from two separate experiments and equal amount of pooled proteins from three wells were subjected to Western blot analysis for senescence markers and regulators p53 and pERK1/2 (D), integrin β3 and PAI-1 (E) using specific antibodies.
