Cells have an internal skeleton that maintains their structure and also drives their movement. Known as the cytoskeleton, ...

Flip open an intro-to-biology textbook and you’ll likely find a cartoon image of the basic cell structure, with its kidney-bean shaped, round and oblong organs—called organelles—spread out with unique ...

Researchers have identified an entirely new mechanism underlying the development and structure of the nervous system during embryogenesis. Researchers at the San Diego branch of the Ludwig Institute ...

Identifying and delineating cell structures in microscopy images is crucial for understanding the complex processes of life. This task is called "segmentation" and it enables a range of applications, ...

Scientists now have the ability to label cell parts in bright fluorescent colors, render tissue slices in high-definition photos and use video to monitor animal behavior down to the milliseconds.

Clinical translation of human pluripotent stem cells (hPSCs) requires advanced strategies that ensure safe and robust long-term growth and functional differentiation. We recently reported the ...

Fundamental flaws in embryonic development may make therapeutic cloning of nonhuman primates difficult, and reproductive cloning of primates – nonhuman and human alike – impossible, a team of ...
