要怎样才能大量再生骨骼呢？典型的骨骼重生——是从病人的臀部取出骨骼，然后移植到身上损坏的骨头处——这种方法有一定的局限性且术后的几年内都会产生剧烈的疼痛。在这个演讲里，茉莉•史蒂芬介绍了一种新的干细胞应用方法，能带动骨骼自身的能力去再生和制造大量的骨骼组织，并且大大减少疼痛。

培育骨骼的新方法

New approaches in regenerative medicine are making it possible to grow large amounts of bone inside the body, bypassing the pain and limits of traditional bone grafting. By cleverly harnessing the body’s own stem cells using a simple injected gel, researchers create on-demand bone that can be harvested with minimal aftereffects. This breakthrough eliminates the need for painful iliac crest harvesting, which can leave patients suffering for years. The same principles are now inspiring advances in tissue engineering for cartilage and even heart repair.
