What do you get when you combine chicken embryos, a gene named after a video game character, and a couple of scientists? A brand-new study that’s confirmed a key element in feather evolution, after it ...

A growing body of work suggests that cell metabolism — the chemical reactions that provide energy and building materials — ...

Feathers are complex skin structures, and their evolutionary beginnings are still a subject of scientific debate. Scientific ...

UCSC scientists have used CRISPR to develop programmable embryoids that can be used to study early embryo development and ...

Inhibiting the sonic hedgehog (Shh) pathway strongly perturbs feather development in chickens by restricting feather bud outgrowth, invagination and ...

Scientists uncovered a key genetic pathway in the origin of feathers, but they found that evolution is stubborn in turning ...

Using CRISPR-based engineering methods to prompt stem cells to organize into embryo-like structures, scientists at UC Santa Cruz were able to create “programmable” cellular models of embryos without ...

The earliest days after fertilization, once a sperm cell meets an egg, are shrouded in scientific mystery.The process of how a humble single cell ...

Scientists have found a way to study early embryonic development without real embryos. Using CRISPR, they programmed stem cells to self-organize into structures mimicking early embryos. The cells show ...

Inhibiting the sonic hedgehog (Shh) pathway strongly perturbs feather development in chickens by restricting feather bud ...

The pluripotent and multipotent stem cells are found in the bone marrow, which can differentiate into any tissue in the body.
