development, cell & molecular biology

Researchers use imaging to show how actin fibers tilt and then swirl to create left-right asymmetry in the cell.

Bacteria in the gut influence the production of antibodies and themselves secrete metabolites. In a pregnant woman, these compounds may influence immune development of her fetus.

The University of California, Davis, professor is a pioneer in teasing apart the changes in gene expression that drive root development.

Elevated levels of a neurotoxin in northeastern Brazil’s drinking water and a high incidence of microcephaly in the region led scientists to look for a link, and they found one.

A zinc-sensing protein found in fruit fly intestines regulates the insect’s growth and feeding behavior.

The extremely rare event, thought to be caused by two sperm cells fertilizing the same egg simultaneously, was last reported in 2007.

Children born to moms who smoked or ingested marijuana during pregnancy suffer higher rates of depression, hyperactivity, and inattention.

A study of chemical tags on histone proteins hints at how the same genome can yield very different animals.

The embryo, grown in a dish from several types of stem cells, went through gastrulation, a significant stage in development.

The finding confirms that a cluster of cells that directs the fate of other cells in the developing embryo is evolutionarily conserved across the animal kingdom.

From guiding branching neurons in the developing brain to maintaining a healthy heartbeat, there seems to be no job that the immune cells can’t tackle.

In addition to circulating in the blood as immune sentinels, macrophages play specialized roles in different organs around the body.

A new assay shows that cells use lamellipodia as their primary mechanism to seal up holes in epithelial tissue.

Researchers identify a gene that drives a type of cellular suicide that differs from the more commonly observed apoptosis phenomenon.

For the first time researchers have demonstrated the molecular tango that gives rise to repeating patterns in developing animal embryos.
