He labeled proteins and followed them in their journey through the cell. He observed that the lysosomes described by de Duve contained fragments of the labeled proteins, and concluded that ...

Trafficking occurs in both directions; the forward direction takes vesicles from the site of synthesis to the Golgi apparatus and next to a cell's lysosomes or plasma membrane. Vesicles that have ...

The ability to grow cells in culture is an important and recognised part of biomedical research, but getting the culturing conditions correct for any particular type of cell is not always easy. These ...

Each component of a cell has its own function. Animal and plant cells differ and they have similarities. Nucleus, cell membrane, cytoplasm and mitochondria are four cell components that are found ...

The Journal of Neuroscience, Vol. 41, Issue. 5, p. 911. This new edition of Nerve Cells and Animal Behaviour has been updated and expanded by Peter Simmons and David Young in order to take into ...

Similar studies have suggested stem cells' potential for conditions such as diabetes and spinal cord injury. Critics point to worrisome animal research showing that embryonic stem cells sometimes ...

Created with Sketch. Animal sampling is taking a group of animals from a larger population for measurement. The findings are then used to make generalized conclusions about the whole population.

The technology could also reduce our reliance on animal testing. A loss of salt and body fluid can stimulate kidney regeneration and repair in mice, according to a new study led by USC Stem Cell ...

A solar cell is made of two types of semiconductors, called p-type and n-type silicon. The p-type silicon is produced by adding atoms—such as boron or gallium—that have one less electron in their ...

According to many experts, we may soon find ourselves using fuel cells to generate electrical power for all sorts of objects we use every day. A fuel cell is a device that uses a source of fuel ...
