Researchers at the Icahn School of Medicine at Mount Sinai have characterized how cellular senescence—a biological process in ...

Every cell in a body contains the same genetic sequence, yet each cell expresses only a subset of those genes. These cell-specific gene expression patterns, which ensure that a brain cell is different ...

Scientists can peer into cells to get a limited view of their activity using microscopes and other tools. However, cells and ...

Descriptions of the embryo go back at least to the time of Aristotle, but it has only been since the late 19 th century and early 20 th century that advances in experimental approaches allowed ...

Scientists have uncovered a new way embryonic cells divide when conventional mechanisms fail. Cell division underpins all ...

The rising incidence of cancer worldwide has led to an increasing number of surgeries that involve the removal of lymph nodes ...

The story of the cell cycle is often told only through the perspective of the chromosomes as they replicate and then divide. This resource beautifully illustrates the role of the cytoskeleton in that ...

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 ...

Cells do more than carry out chemical reactions. New theoretical work suggests they may also generate usable electrical energy through constant motion in their membranes, offering a fresh way to think ...

Researchers at the Francis Crick Institute 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 ...
