Scientists are exploring ways to mimic the origins of human life without two fundamental components: sperm and egg. They are coaxing clusters of stem cells – programmable cells that can transform into ...

Researchers have uncovered a surprising new role for netrin1, a crucial protein in neural development, as a regulator that limits bone morphogenetic protein signaling in the developing spinal cord.

Netrin1 is a protein that was first characterized for its axon guidance activities during embryonic development. The netrin family has been shown to play many critical roles in developmental and ...

Scientists have created synthetic blobs that resemble a 14-day-old human embryo for the first time, meaning they can study embryo development beyond a particularly tricky period of pregnancy.
