Summary
This study by Hoffecker, I. T. & Iwata, H was published in Tissue Engineering Part A 20, 1643–, 1653. It utilized Microtissues 3D Petri Dish® micro-molds for 3D cell culture, contributing to advances in stem cell biology research.
Manipulation of Cell Sorting Within Mesenchymal Stromal Cell–Islet Cell Multicellular Spheroids
Research Overview
Placing islets alongside immunoprivileged mesenchymal stromal cells could protect transplanted islets. This study created single-cell suspensions of MSCs and dissociated islet cells on arrays of round-bottomed wells and watched what happened: the two populations segregated within three days.
When the ROCK inhibitor Y-27632 was included during co-aggregate preparation, the aggregates sorted into core-shell structures with islet-derived cells on the exterior and MSCs in the core. Immunostaining showed MSC-derived regions transitioning from N-cadherin, vimentin, and CD44 expression toward E-cadherin — demonstrating that cell sorting within co-aggregates can be deliberately manipulated.
