Core–Shell Spheroid?Laden Microgels Crosslinked under Biocompatible Conditions for Probing Cancer?Stromal Communication

Multicellular cancer spheroids (MCSs) have emerged as a promising in vitro model that recaptures many features of solid tumours vivo. To generate spheroids, cells are encapsulated microgels with high throughput. While the biophysical properties spheroid and biomaterial influence function behavior cells, characterization these remains largely unexplored. In addition, existing techniques lack control over cell positioning, resulting formation large variability. Herein, versatile, microfluidic platform for generating biocompatible core–shell uniform is reported. an situ micromechanics measuring device to determine stiffness individual artificial niches used. The power microfluidics-based method by making MCS-laden interactions stromal demonstrated. Together vivo data, it shown tumor proliferation promoted cocultured fibroblasts.
