Two coauthors of a new study discuss their findings about nearly 170 facilities in the southwestern US selling unproven therapies—and what should be done about them.

Insulin-producing cells grown in the lab could offer a functional cure for the disease.

The introduced cells engrafted in the nose, became olfactory sensory neurons, and sent axons to the animals’ brains.

Age-related macular degeneration patients who received injections of retinal cells derived from donors’ induced pluripotent stem cells have maintained their level of eyesight for a year.

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.

A zebrafish model of the birth defect craniosynostosis provides insights into how the condition develops.

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.
