Speedy computation enables scientists to reconstruct an animal's development cell by cell

Recent advances in imaging technology are transforming how scientists see the cellular universe, showing the form and movement of once grainy and blurred structures in stunning detail. But extracting the torrent of information contained in those images often surpasses the limits of existing computational resources. Now, researchers have created a new computational method to rapidly track the three-dimensional movements of cells in such data-rich images.

Measuring the number of protein molecules inside cells

Scientists were able to measure the amount of protein molecules in living human cells required to form an important structure of the chromosome, the centromere. This study presents new methodologies that may also be used to unveil other biological problems.

Scientists find genetic recipe to turn stem cells to blood

The ability to reliably and safely make in the laboratory all of the different types of cells in human blood is one key step closer to reality. Stem cell researchers now report the discovery of two genetic programs responsible for taking blank-slate stem cells and turning them into both red and the array of white cells that make up human blood.

Dental pulp stem cells promote the survival and regeneration of retinal cells after injury

Injury to the retina and optic nerve leads to irreversible loss of retinal ganglion cells (RGCs) and irreparable damage to their axons which ultimately leads to blindness. Providing a sustained source of neurotrophic growth factors is required to promote their survival and regeneration. Transplanted dental pulp stem cells secrete multiple growth factors which protect RGCs from death after optic nerve injury and promote regeneration of their axons.
