Hidden stem cells may be fueling spinal stenosis

Scientists have discovered a stem cell that appears to serve as a master source for tendon and ligament cells throughout the body. In lumbar spinal stenosis, these cells become unusually active and may drive the ligament overgrowth that squeezes spinal nerves and causes pain, numbness, and difficulty walking. Researchers found that reducing calcium signaling stopped this abnormal growth in mice.

Stem cells reverse stroke damage and restore movement in mice

Stem cell transplants helped regenerate stroke-damaged brain tissue in mice, producing new neurons and restoring lost motor function. The treatment also improved blood vessels, inflammation, and the blood-brain barrier, raising hopes that a similar approach could eventually help repair the human brain after stroke.
