The devices, which could one day treat children with esophageal atresia and short bowel, were recently tested in pigs.

A study confirms that the spaces between cells are fluid-filled, rather than tightly packed with connective tissue, but pathologists say the findings’ implications remain to be seen.

High-resolution MRI reveals that human fetal hearts rapidly develop their major structures within a four-day period.

Tissue “seeds” made up of three cell types and patterned onto a scaffold develop into complex structures with some organ function, researchers show.

Increasingly sophisticated tissue organoids can model many aspects of disease, but animal studies retain a fundamental role in research, scientists say.
