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

Without knowing the cells’ mechanism of action, researchers question the best way to administer them to patients.

Among 11 infants treated to date, most survived and their heart function improved.

An investigation finds regenerative medicine researcher Suchitra Sumitran-Holgersson manipulated data in seven papers.

The miniscule carriers successfully transported and released live cells at a particular location within living mice.

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.  

The woman’s own cartilage was used to construct the transplant after she lost her left ear in a car crash.

The extracellular matrix appears to inhibit regeneration; but scientists debate whether heart muscle really comes back.  

Researchers used a trio of transcription factors to transform pancreatic duct cells in vivo into β-like cells that secrete insulin and improve diabetes symptoms.
