The lab-made organoids are fully functional, the team reports, and could aid the study of vascular-related diseases such as diabetes.

Changes in gene expression also hint at how the brains of people with ASD develop differently from those of other people.

Critics say the misleading term actually refers to a heterogeneous population of cells, including possible tissue-specific progenitor cells and nonstem cells all lumped together.

Researchers recovered the cells that give rise to bone and cartilage from fetal and adult bone marrow and also derived them from induced pluripotent stem cells.

A mouse study adds to the growing body of work disputing the ability of progenitor cells to regenerate muscle tissue in adult mammals’ hearts.

Numerous cellular changes underlie the decline of muscle mass and strength in the elderly.

Researchers untangle the multifarious nature of muscle aging. So far, the only reliable treatment is exercise.

The stem cell–derived transplants were stable for 24 months and led to wide-ranging behavioral improvements in the monkeys.  

The first human experiment with neural precursor cells implanted to treat chronic spinal cord injury suggests the procedure is safe, and hints at a small benefit.
