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 ...

Not junk: 'Jumping gene' is critical for early embryo

A so-called "jumping gene" that researchers long considered either genetic junk or a pernicious parasite is actually a critical regulator of the first stages of embryonic development, according to a new study in mice led ...

How stem cells move

Scientists from Newcastle University have shown that human embryonic stem cells move by travelling back and forth in a line, much like ants moving along their trails.

Researchers glimpse elusive stem cell in the early embryo

Stem cell researchers at Harvard Medical School and Boston Children's Hospital have, for the first time, profiled a highly elusive kind of stem cell in the early embryo—a cell so fleeting that it makes its entrance and ...

A first look at the earliest decisions that shape a human embryo

The factors that shape the destiny of a cell, like that of a fully formed person, remain something of a mystery. Why, for example, does one stem cell in a human embryo become a neuron rather than a muscle cell? And why does ...
