Stem Cell Therapy for Stroke Shows How Cells Find Their Way in the Brain
 The human brain is not a fast-healing organ. Normally it doesn't need to be as adult brain cells are stable and last for a lifetime. When trauma or disease such as a stroke occurs, the brain struggles to bounce back because it has a limited ability to regenerate lost cells.
Stem cell therapy is a promising method for boosting regeneration in the brain, but transplanted cells have struggled to replace damaged tissue and reestablish broken circuits. In a new study of a therapy derived from human stem cells and transplanted into mice, the cells matured, integrated into existing circuits and restored function. By tracing the cells and sequencing their gene expression patterns, the researchers also revealed how transplanted cells find where they need to go and form connections with the nervous system.
