Scientists uncover the promise of mesenchymal stem cells (MSCs), also known as medicinal signaling cells, to modulate the immune system and regenerate tissue.

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.

A study finds similarities between cells that heal wounds and those that lead deadly cancerous invasions.

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.

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

Scientists have manipulated the electrical signals that help guide flatworms in regenerating their body parts to encourage a flatworm to grow two heads.

The eel-like lamprey can return to normal swimming and burrowing after suffering a severed spinal cord twice.

At magnetic field intensities somewhat above that of Earth, stem cell proliferation shifts gears.
