TED-ED: How to grow a bone - Nina Tandon

The video explores the potential of growing human bones outside the body by first understanding natural bone growth. It explains how bones develop from cartilage in a fetus, reinforced by osteoblasts and osteoclasts. The video discusses Wolff's law, which states that bones strengthen with use, and highlights the challenges of traditional bone repair methods. It introduces innovative techniques using stem cells and bioreactors to grow bones tailored to patients' needs, simulating body conditions to ensure proper development. While successful in animals, human trials are anticipated.

What is Wolff's law and how does it relate to bone strength?

Describe the process of growing a bone using a patient's own cells.
