Matrix Stiffness Regulates Mechanotransduction and Vascular Network Formation of hiPSC-Derived Endothelial Progenitors Encapsulated in 3D Hydrogels

Jiwan Han, Kathleen N. Halwachs, Toni West…·Janet Zoldan

This study shows that vascular network formation by hiPSC-derived endothelial progenitors in 3D hydrogels depends on matrix stiffness, contractility, and cell-induced remodeling, not just mechanotransduction.

Dynamic Stiffening to Improve Vasculogenesis of hiPSC-Derived Endothelial Progenitors

Brett Stern, Jiwan Han, Kathleen N. Halwachs…·Janet Zoldan

This study shows that dynamically adjusting hydrogel stiffness during vasculogenesis improves vascular network formation, while late stiffening disrupts it, with effects mediated by FAK and Rho kinase.

The Interrelation Between the 3D Microenvironment and Mechanis of Human Induced Pluripotent Endothelial Progenitors

Toni M. West, Jiwan Han, Gabriel Peery…·Michael S. Sacks

This study examines how 3D microenvironment mechanics influence hiPSC-derived endothelial progenitor cell self-assembly and network formation.
