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.

New insights on conditions for new blood vessel formation

With lifesaving applications possible in both inhibiting and accelerating the creation of new blood vessels, a more fundamental understanding of what regulates angiogenesis is needed. Now, researchers have uncovered the existence of a threshold above which fluid flowing through blood vessel walls causes new capillaries to sprout.
