Angiogenesis induction using organoid-tissue modules: A platform for modular vessel construction.

ABSTRACT: Angiogenesis is essential for successful tissue regeneration, particularly in clinical contexts such as ischemic injury, wound healing, and reconstructive therapies. However, the establishment of functional vasculature remains a major limitation in organoid-based systems. In this study, we developed vascularized organoid tissue modules (Angio-TMs) by incorporating human umbilical vein endothelial cells (HUVECs) into scaffold-free, self-organized constructs. Remarkably, the inclusion of HUVECs at 1% of the total cell population was sufficient to generate highly reproducible and structurally stable Angio-TMs, which exhibited clear endothelial differentiation and vascular functionality both in vitro and in vivo. Furthermore, inhibition of transforming growth factor (TGF)-β signaling in Angio-
