Cells constantly shift and transform, triggering the complex choreography that shapes living organisms. Whether dividing into new cells or sculpting an embryo, these tiny movements rely on chemical ...

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

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 ...

Using CRISPR-based engineering methods to prompt stem cells to organize into embryo-like structures, scientists were able to create 'programmable' cellular models of embryos without ever experimenting ...

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

“Reduced telomere length can be caused by embryonic cellular damage,” said study co-lead Dr. Yasmyn Winstanley. The ...

It may be disturbing to characterize human bodies in such commodifying terms, but the unavoidable reality is that human ...

Only recently has the ribosome—one of the oldest molecular machines in evolutionary terms—been recognized as an active ...

First Mouse With Two Male Parents to Reach Adulthood Jan. 28, 2025 — A team of stem cell scientists have successfully used embryonic stem cell engineering to create a bi-paternal mouse -- a ...

Life takes shape with the motion of a single cell. In response to signals from certain proteins and enzymes, a cell can start ...

Women with polycystic ovary syndrome (PCOS) find it harder to get pregnant, have more frequent miscarriages and have a higher ...

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