The perfect tempo within the cells to develop vertebrae

Timing is everything when it comes to the embryonic development of pre-vertebrae divisions along the body of an embryo, according to researchers in Japan. A new live-imaging technique in mouse cells suggests a specific clock ...

Research team brings computation and experimentation closer together

A bioengineering group from the University of Pittsburgh Swanson School of Engineering is bringing the worlds of computational modeling and experimentation closer together by developing a methodology to help analyze the wealth ...

Growing embryonic tissues on a chip

It's no surprise that using human embryos for biological and medical research comes with many ethical concerns. Correct though it is to proceed with caution in these matters, the fact is that much science would benefit from ...

When a fish becomes fluid

Zebrafish aren't just surrounded by liquid, but turn liquid—in part—during their development. As the zebrafish embryo develops from a ball of cells to a fully-formed fish, a region of the embryo switches its phase from ...

Team uncovers the underlying mechanisms of 3-D tissue formation

If you want to build an organ for transplant, you need to think in 3-D. Using stem cells, scientists are now able to grow parts of organs in the lab, but that is a far cry from constructing a fully-formed, functioning, three-dimensional ...

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 ...

Measuring the hardness of living tissues without damage

When a fertilized egg is developing into a fetus, cell populations forming tissues are in a fluid state, and thus, the tissue can be easily deformed. Cells also generate mechanical forces during development that contribute ...
