Low-cost workflow creates 100,000 uniform cell capsules with standard lab tools

Cells are typically studied outside the body under controlled laboratory conditions. However, conventional flat cell culture methods do not fully reproduce the complex three-dimensional environments that cells experience in living tissues. Tiny hydrogel capsules offer one way to culture cells in a confined three-dimensional space, allowing researchers to study how cells grow, organize and interact under more tissue-like conditions. Current methods to do this come with a high cost and a set of requirements that put such research out of reach to many.
