23 Jul METHODS OF GENERATING FUNCTIONAL HUMAN TISSUE
Abstract
Methods of tissue engineering, and more particularly methods and compositions for generating various vascularized 3D tissues, such as 3D vascularized embryoid bodies and organoids are described. Certain embodiments relate to a method of generating functional human tissue, the method comprising embedding an embryoid body or organoid in a tissue construct comprising a first vascular network and a second vascular network, each vascular network comprising one or more interconnected vascular channels; exposing the embryoid body or organoid to one or more biological agents, a biological agent gradient, a pressure, and/or an oxygen tension gradient, thereby inducing angiogenesis of capillary vessels to and/or from the embryoid body or organoid; and vascularizing the embryoid body or organoid, the capillary vessels connecting the first vascular network to the second vascular network, thereby creating a single vascular network and a perfusable tissue structure.
