The source of stem cells points to two proteins

Mammalian embryos are unlike those of any other organism as they must grow within the mother's body. While other animal embryos grow outside the mother, their embryonic cells can get right to work accepting assignments, such ...

Study demonstrates 'tunability' of a molecular chaperone

For decades, molecular biologists studying a class of molecular chaperones known as heat shock proteins (Hsp70s) have relied on the Hsp70s found in bacteria as the model system. Now one of the world's experts on the molecule ...

Tampering with cellular fats holds great promise

Today, much of the biology underlying the cellular composition of lipids is a black box to scientists. Even though lipids are a major group of biomolecules, they are difficult to study because their synthesis is regulated ...

Stem cells organize themselves into pseudo-embryos

The definitive architecture of the mammalian body is established shortly after implantation of the embryo in the uterus. The antero-posterior, dorso-ventral and medio-lateral axes of the body become organized under the control ...

Chemists design 'miniecosystems' to test drug function

Scripps Research scientists have solved a major problem in chemistry and drug development by using droplet-sized 'miniecosystems' to quickly see if a molecule can function as a potential therapeutic.
