Fasting causes liver cell division
Cells in the adult liver were thought to divide rarely. But a study led by Stanford Medicine researchers found intermittent fasting causes rapid cell division.

Antibody treatment rejuvenates stem cells
Old muscle stem cells express high levels of the cancer-associated molecule CD47. Blocking a pathway mediated by CD47 restored strength to old mice in a Stanford Medicine study.

Mice with diabetes regain blood sugar control
A technique developed at Stanford Medicine allows mice with diabetes to accept unmatched islet cells and durably restores blood sugar control without immunosuppression or graft-versus-host disease.

Brain cell transplantation aids research
Lab-grown clusters of human brain cells integrate so well into young rats’ brains they enable researchers to study neurodevelopmental disorders’ molecular and circuit underpinnings.

Step toward growing organs
Researchers have shown initial viability of an embryo that contains both chimpanzee and macaque cells in a preliminary study that explores the feasibility of primate organ genesis.

Ketogenic diet helps cells survive stress
Muscle stem cells enter a deep resting state during fasting or when fed a high-fat ketogenic diet, a Stanford-led study finds. This promotes stem cell resilience but slows injury repair.

Electric current aids stroke recovery
Stanford scientists have developed a device that delivers and electrically stimulates stem cells to promote stroke healing.

Hyperexcitable neurons drive sleep instability
Researchers have identified a mechanism underlying fragmented sleep with older age, paving the way for potential drug therapies.

Molecule restores strength in old mice
A single protein is a master regulator of mouse muscle function during aging, a Stanford study finds. Blocking this protein increased muscle strength and endurance in old animals. It may play a role in age-related muscle weakening in humans.
