Research identifies earlier origin of neural crest cells

Neural crest cells—embryonic cells in vertebrates that travel throughout the body and generate many cell types—have been thought to originate in the ectoderm, the outermost of the three germ layers formed in the earliest ...

Embryo's early development revealed in a dish

During embryonic development, the entire nervous system, the skin and the sensory organs emerge from a single sheet of cells known as the ectoderm. While there have been extensive studies of how this sheet forms all these ...

Study answers longstanding cell-development riddle

During the lifetime of a body—whether human, fish or any other type of vertebrate—cells die, making room for fresh new cells to carry on vital processes. The dead cells must be cleared away, though, and debris removal ...

How to make fish shine

Scientists from the University of Bath have helped to figure out why shoals of fish flash silver as they twist through the water by studying how the shiny silver cells are created in zebrafish.

Silver fox study reveals genetic clues to social behavior

In 1959, Russian scientists began an experiment to breed a population of silver foxes, selecting and breeding foxes that exhibited friendliness toward people. They wanted to know if they could repeat the adaptations for tameness ...

Fluorescent fish genes light path to neuroblastoma

A new type of zebrafish that produces fluorescent tags in migratory embryonic nerve precursor cells could help a Rice University neurobiologist and cancer researcher find the origins of the third-most common pediatric cancer ...
