Hydrogel (1 of 2) (image) Rice University Share Print E-Mail Caption The proposed mechanism of healing in hydrogels developed at Rice University starts with (A) injectable peptide scaffolds that form nanofibrous hydrogels. (B) Macrophages and endothelial cells infiltrate the scaffold. (C) Vessels progress from immature (endothelial cells only) to stabilized (endothelial and pericyte cells) to mature (endothelial, pericyte and smooth muscle cells). (D) Mature neovessels rapidly form in just seven days in the subcutaneous model.
