Researchers transform human blood cells into functional neurons

Human immune cells in blood can be converted directly into functional neurons in the laboratory in about three weeks with the addition of just four proteins, researchers at the Stanford University School of Medicine have ...

Hairy skin grown from mouse stem cells

Indiana University School of Medicine researchers have cultured the first lab-grown skin tissue complete with hair follicles. This skin model, developed using stem cells from mice, more closely resembles natural hair than ...

Human skin cells transformed directly into motor neurons

Scientists working to develop new treatments for neurodegenerative diseases have been stymied by the inability to grow human motor neurons in the lab. Motor neurons drive muscle contractions, and their damage underlies devastating ...

Cellular reprogramming reverses signs of aging

Graying hair, crow's feet, an injury that's taking longer to heal than when we were 20—faced with the unmistakable signs of aging, most of us have had a least one fantasy of turning back time. Now, scientists at the Salk ...

Lab-grown stem cells regenerate monkey hearts: study

In a step forward for organ regeneration, stem cells grown from a single monkey's skin cells revitalised the damaged hearts of five sick macaques, scientists reported Monday.

Study finds a patchwork of genetic variation in the brain

It was once thought that each cell in a person's body possesses the same DNA code and that the particular way the genome is read imparts cell function and defines the individual. For many cell types in our bodies, however, ...
