Diagrammatic representation of results of growth factors’ quantification in P-ECM hydrogels by ELISA and viability assay in response to rDPSCs. (a) line graph showing the release curve of VEGF in ng/L in P-ECM hydrogel at 0 days, 1 day, and 7 days; (b) line graph showing the release curve of bFGF in ng/L in P-ECM at 0 days, 1 day, 5 days and 14 days; (c) line graph showing the release curve of TGF-β1 in pg/mL in P-ECM at 0 days, 1 day, 5 days and 14 days; (d) line graph showing the release curve of BMP2 in pg/mL in P-ECM hydrogel at 0 days, 1 day, 5 days, and 14 days; (e) bar graph showing rDPSCs viability % after 24 h and 3 days in response to P-ECM. Viability % was calculated by normalizing the absorbance values to those of 30,000 rDPSCs measured at baseline
