Mind the gap: Space inside eggs steers first few steps of life

Imagine sitting at a meeting where the shape of the table and your place at it might impact how you get along with the other members. Cells also communicate with their nearest neighbors, and in embryos, nothing is left to ...

A new dimension in stem cell signaling

Divide, differentiate or die? Making decisions at the right time and place is what defines a cell's behavior and is particularly critical for stem cells of an developing organisms. Decision making relies on how information ...

Rice production depends on TAB1 gene, researchers find

Rice has long been a staple food for more than half the global population. The United Nations even declared 2004 the International Year of Rice to raise awareness and encourage action to protect and advance the crop for a ...

Repulsive interactions bring rapid mitotic divisions to order

A fertilized egg cell is a common starting point for most animals. Generally, duplication of the genetic material in this cell marks the start of several rounds of division that eventually give rise to a multicellular organism. ...

Stem cell study paves way for manufacturing cultured meat

Scientists have for the first time obtained stem cells from livestock that grow under chemically defined conditions, paving the way for manufacturing cell cultured meat and breeding enhanced livestock.

How random is stem cell development?

In just a few weeks a completely new organism develops from a fertilized egg cell. The real miracle is that a bunch of identical stem cells turns into completely different, specialized cell types. A team led by Christian ...

How do developing spinal cords choose 'heads' or 'tails'?

The progression from a round ball of cells to an embryo with a head and a tail is one of the most critical steps in an organism's development. But just how cells first start organizing themselves with directionality along ...
