Encapsulated Arrays of Self-Assembled Microtissues: An Alternative to Spherical Microcapsules
Research Overview
Micro-encapsulation could treat metabolic disorders by immuno-isolating transplanted cells, but decades of work on spherical microcapsules have not achieved full clinical potential. This study proposes an alternative geometry: an alginate-encapsulated array of self-assembled 3D microtissues.
Monodispersed HepG2 cells seeded onto a micro-molded agarose gel settled into the recesses and self-assembled into 822 microtissues within 24 hours. The densely packed array was encapsulated in situ with alginate; once separated from the mold, the encapsulated array held microtissues close to its surface — a configuration favoring exchange with the host compared with conventional spherical capsules.
