Scientists reveal unprecedented insights into human limb development, including the many intricate processes that govern their formation.

An ambitious project launched in 2016 has made a dent in one of biology’s greatest challenges — with more than 3,600 researchers profiling more than 100 million cells.

In the past, scientists believed that the fast-acting biochemistry of genes and proteins was responsible for directing the ...

Scientists published more than three dozen papers as part of the Human Cell Atlas, an effort to map the human body cell by cell.

Early human development is a complex, multistep process that’s even more complicated to study in the lab. Models made from stem cells avoid some of the trouble with using real human embryos.
