Understanding biology’s software—the rules that enable great plasticity in how cell collectives generate reliable anatomies—is key to advancing tissue engineering and regenerative medicine.

Planarian flatworms grow to double their normal size when scientists inhibit a gene that suppresses growth.

Physicists, geneticists, computer scientists, and biologists are working together to gain a full appreciation of the intricacies of organismal growth and form.

A study in mice reveals that stem cell transplants, currently in clinical trials, may not actually require the cells.

Collagen inside ankles has more turnover than that in hips, thanks to the action of microRNAs.

The funding future is uncertain for researchers studying topics including cancer, stem cells, and the Arctic.

The FTC, in its first crack down on the industry, gets two California companies selling unproven treatments to stop their false advertising and pay a fine.

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.

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.
