Cells contain a blueprint in the form of DNA that dictates what they can make. This blueprint is converted into a message, or mRNA, which is then converted into protein. Although DNA remains the same ...

Biologists have developed an efficient way to genetically modify human embryonic stem cells. Their approach, which uses bacterial artificial chromosomes to swap in defective copies of genes, will make ...

Scientists at the University of Illinois at Chicago have identified a molecular mechanism that directs embryonic stem cells to mature into endothelial cells that form blood vessels. Understanding the ...

A House bill that would allow federal funding of stem cell research using human embryos donated by fertility clinics that would otherwise discard them has sparked a heated debate on Capitol Hill. Two ...

AHA: Stem Cell Therapy May Aid Ischemic Stroke Recovery Modification of aged human cardiac progenitor cells (hCPCs) from elderly patients with Pim-1, a protein that promotes cell survival and growth, ...

A discovery, several years in the making, demonstrates that adult skin cells can be converted into neural crest cells (a type of stem cell) without any genetic modification, and that these stem cells ...
