  • Vascularized biphasic tissue constructs
    Patent number: 11213614
    Abstract: Biphasic tissue constructs that include a scaffold having one or more channels, a vascular portion comprising a hydrogel at least partially disposed in the one or more channels, and a first bioactive growth factor and a second bioactive growth factor different from the first bioactive growth factor, the first bioactive growth factor localized to the scaffold and the second bioactive growth factor localized to the vascular portion. The first bioactive growth factor may be bone morphogenetic protein 2 (BMP2) peptide and the second bioactive growth factor may be vascular endothelial growth factor (VEGF) peptide.
