Divide and Define: Clues to Understanding How Stem Cells Produce Different Kinds of Cells
May 5, 2013 — The human body contains trillions of cells, all derived from a single cell, or zygote, made by the fusion of an egg and a sperm. That single cell contains all the genetic information needed to ... > full story -
Heart Cells Change Stem Cell Behavior
May 2, 2013 — Stem cells drawn from the amniotic fluid of pregnant women change their behavior when near heart cells, but do not become heart ... > full story -
Scientists Revolutionize Creation of Genetically Altered Mice to Model Human Disease
May 2, 2013 — Scientists have efficiently created mouse models with multiple gene mutations in a matter of weeks. Because the method does not require embryonic stem cells, the approach also could allow any animal ... > full story -
Investigating Devastating Childhood Diseases Just Got Easier
May 2, 2013 — Induced pluripotent stem cells (iPScs) from the skin of patients with Dravet syndrome (DS) show Dravet-like functional impairment when they are converted into neurons, finds new research. This method ... > full story -
The Many Faces of the Bacterial Defense System
April 30, 2013 — Even bacteria have a kind of "immune system" they use to defend themselves against unwanted intruders -- in their case, viruses. Scientists were now able to show that this defense system is much more ... > full story -
