Induction of Four‐Dimensional Spatiotemporal Geometric Transformations in High Cell Density Tissues via Shape‐Changing Hydrogels

Developing and healing tissues begin as cellular condensations. Spatiotemporal changes in tissue geometry, transformations in the spatial distribution of the cells, and extracellular matrix are essential for its evolution into a functional tissue. 4D materials, 3D materials capable of geometric chan...
