The Wiring of a Zebrafish Embryo

The body-wide network of neurons is established in the early development of a zebrafish and is essential for the function of neuronal circuits. In stark contrast, fibroblasts are thought to be solitary cells. However, their network-like organisation has raised the question whether these connections between fibroblasts might play a role beyond current textbook knowledge in their behaviour in processes such as development, cancer and regeneration. The picture shows both the neurons (magenta) and fibroblasts (green) as they dynamically establish a network in a 2 days old zebrafish embryo.
