A color-changing tag shows changes in a 'detector' molecule's age depending on how much 'guidance' molecule cells encounter. Darren Gilmour and colleagues discovered that these zebrafish embryo cells ...

During development, cells move around constantly. Often, specific cell types arise in one area of the developing organism but then need to migrate to another destination as the organism grows and ...

Scientists uncover how zebrafish switch between cell division and direct differentiation to rebuild sensory organs, challenging long-held views on tissue regeneration. Study: Stem and progenitor cell ...

While humans can regularly replace certain cells, like those in our blood and gut, we cannot naturally regrow most other parts of the body. For example, when the tiny sensory hair cells in our inner ...
