© 2020 Elsevier B.V. In the current work, our purpose was based on the assessment of bioactive chitosan (CS)/Poly(ethylene glycol) diacrylate (PEGDA) based scaffolds ability to stimulate in vitro angiogenesis process. The bioactivation of the scaffolds was accomplished by using organic (BMP-2 peptide) and inorganic (hydroxyapatite nanoparticles) cues. In particular, the properties of the materials in terms of biological response promotion on human umbilical vein endothelial cells (HUVECs) were studied by using in vitro angiogenesis tests based on cell growth and proliferation. Furthermore, our interest was to examine the scaffolds capability to modulate two important steps involved in angiogenesis process: migration and tube formation of cells. Our data underlined that bioactive signals on CS/PEGDA scaffolds surface induce a desirable effect on angiogenic response concerning angiogenic marker expression (CD-31) and endothelial tissue formation (tube formation). Taken together, the results emphasized the concept that bioactive CS/PEGDA scaffolds may be novel implants for stimulating neovascularization of tissue-engineered constructs in regenerative medicine field.
