Stem cells grow and multiply in a self-assembling porous peptide hydrogel. Actin filaments from the cells’ cytoskeleton are stained green in this confocal microscope image; stem-cell nuclei are blue. Researchers hope materials such as this hydrogel (not visible in the image) can be used as scaffolds for stem-cell-based tissue regeneration.
