How sperm stem cells maintain their numbers

The steady production of sperm relies on the number of sperm stem cells in the testis remaining constant. Researchers including Assistant Professor Yu Kitadate and Professor Shosei Yoshida (developmental biologists at the ...

Determining the shape of cells

Cells are constantly performing small tasks such as repairing wounds. They exert force by changing shape. But how do cells translate their shape into exerting a force in a specific direction? Experimental and theoretical ...

New mechanism clarifies how cells migrate

Similarly to cars, cells need a steering mechanism that guides them towards a certain target or direction. Scientists at the Center for Cognition and Sociality (Institute for Basic Science, IBS), and KAIST, led by Prof. HEO ...

Researchers transform common cell to master heart cell

By genetically reprogramming the most common type of cell in mammalian connective tissue, researchers at the University of Wisconsin-Madison have generated master heart cells—primitive progenitors that form the developing ...

Tissue engineers recruit cells to make their own strong matrix

Imitation may be the sincerest form of flattery but the best way to make something is often to co-opt the original process and make it work for you. In a sense, that's how scientists at Brown University accomplished a new ...
