Aqueous Two‐Phase Bioinks for Discrete Packing and Compartmentalization of 3D Bioprinted Cells

open access: yesAdvanced Healthcare Materials, EarlyView.
Aqueous two‐phase systems (ATPS) enable the formation of biomimetic interfaces crucial for tissue engineering. However, clinical translation remains limited by the challenge of precisely controlling cellular compartmentalization. Here, we developed ATPS biomaterial inks for 3D bioprinting allowing tuneable droplet formation via NaCl modulation.

Spontaneous Helical Alignment of Smooth Muscle Cells to Form a Medial Layer for Engineered Microvasculature

open access: yesAdvanced Healthcare Materials, EarlyView.
Spontaneous helical alignment of smooth muscle cells is induced within resistance‐vessel‐sized channels patterned within a hydrogel. The extent of the cells’ orientation angle is dependent on the presence and composition of ECM proteins lining the channel wall and cell seeding density.
