The Stem Cell Science Round Up

Strong Blood Vessel Graft Created – Vascular grafts have been engineered from iPSC-derived smooth muscle cells with comparable strength to the original blood vessels.

New Method for Lung Regeneration – Through a procedure similar to bone marrow transplantation, investigators were able to induce lung regeneration without the need for chronic immune suppression.

How Stress Causes Grey Hair – Scientists have discovered that stress activates sympathetic nerves that are part of the fight-or-flight response, driving the depletion of pigment-regenerating stem cells in hair follicles.

Biodegradable Bridge for Nerve Injury – Researchers have created a biodegradable scaffold that releases a growth-promoting protein that can regenerate long sections of damaged nerves, without the need for transplanting cells.
