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 ...

Paterna Biosciences says it has determined the set of instructions needed to turn sperm-making stem cells into "normal, ...

STANFORD, Calif. (KGO) -- In the Camarillo bioengineering lab at Stanford, engineers measure impacts both big and small. And that ability can help in research as far ranging as preventing concussions ...

Scientists have grown a human embryo-like structure in a lab which replicates very early human development - including the production of blood stem cells. The lab-grown embryo model could help ...

Paterna Biosciences said it has mastered the molecular signals that teach stem cells how to mature into sperm for a promising ...

According to WIRED, Paterna claims it has worked out the molecular signals needed to turn spermatogonial stem cells into ...
