Scientists at the Institute for Infectious Diseases, University of Bern have developed an in vitro stem cell-based bioassay grown on multi-electrode arrays capable of detecting the biological activity of Clostridium botulinum neurotoxins.
The mystery of what controls the range of developmental clocks in mammals — from 22 months for an elephant to 12 days for an opossum — may lie in the strict time-keeping of pluripotent stem cells for each unique species.
Our blood stem cells generate around a thousand billion new blood cells every day. But the blood stem cells' capacity to produce blood changes as we age.
Working with human breast cancer cells and mice, researchers at Johns Hopkins say they have identified a biochemical pathway that triggers the regrowth of breast cancer stem cells after...
