Cell division, or the process of how daughter cells emerge from a mother cell, is fundamental to biology. Every cell inherits the same protein and DNA building blocks that make up the cell it ...

Every time a stem cell divides, one daughter cell remains a stem cell while the other takes off on its own developmental journey. But both daughter cells require specific and different cellular ...

About 100 cells divide every second in our body. A key protein in cell division is a protein kinase termed Plk1, because it activates other proteins involved in this process. Plk1 is also ...

There is variability in when and how cells divide during the development of embryos. While researchers traditionally believed this variability was an obstacle that needed to be regulated, a group now ...

"Hearst Magazines and Yahoo may earn commission or revenue on some items through these links." Until now, cells dividing by mitosis were thought to grow round and then split into two identical, ...

Researchers at the Max Delbrück Center have found that a cellular housekeeping mechanism called autophagy plays a major role ...

The journey started with an enigma in the zebrafish embryo: some endothelial cells, actively involved in the initial stages of the development of the earliest blood vessels, were dividing in an ...

A new theoretical model helps explain how epigenetic memories, encoded in chemical modifications of chromatin, are passed from generation to generation. Within each cell's nucleus, researchers suggest ...

One of the most diverse ecosystems on the planet is closer than you think - right inside your mouth. Your mouth is a thriving ecosystem of more than 500 different species of bacteria living in ...

Chemists induced a cell-like behavior in molecular assemblies called vesicles. They used a sacrificial chemical fuel to make the vesicles divide into smaller versions of themselves. While this process ...

At the end of the 4-cell stage, embryos divide to the 8-cell stage, forming many different shapes and high variability between embryos. Then, cells increase their surface tension which brings cells ...
