Like a mosaic, the cell membrane is a complex structure made up of many different parts, such as proteins, phospholipids, and cholesterol. The relative amounts of these components vary from ...

Researchers at the Francis Crick Institute have developed a new stem cell model of the mature human amniotic sac, which ...

Researchers have developed a new stem cell model of the mature human amniotic sac, which replicates development of the tissues supporting the embryo from two to four weeks after fertilization. This is ...

Sterols, such as cholesterol in our bodies or ergosterol in yeast cells, are among the most abundant lipids in eukaryotic ...

We established that Onsager’s principle of reciprocity is violated for the cell model of an ion–exchange membrane —the coupled cross kinetic coefficients are not equal. It is crucial when ...
