The cellular and molecular mechanisms of magnetic stimulation-based bone regeneration require further understanding at present. To evaluate the phenomenon in the lab, a three-dimensional (3-D) native collagen model was recently ...
A team of scientists designed a device that can induce partial hindlimb regeneration in adult aquatic African clawed frogs (Xenopus laevis) by "kick-starting" tissue repair at the amputation site. Their findings, appearing ...
Each spring, male deer sprout a new pair of antlers, which are essentially temporary external bones, at a speed unparalleled by the bone growth of other mammals. Now, research led by scientists at the Stanford University ...
As a kid, Michael Sealy was tall. A little clumsy, he says. And he has lasting proof: two metal screws in his left elbow.
Scientists have been searching for ways to develop materials that are as dynamic as living things, with the ability to change shape, move and change properties reversibly.
Coral reefs have long faced problems like overfishing, global warming and pollution—but they're also threatened by how slow they regenerate.
The complex architecture of bone is challenging to recreate in the lab. Therefore, advances in bone tissue engineering (BTE) aim to build patient-specific grafts that assist bone repair and trigger specific cell-signaling ...
Cut off a salamander's tail and, in a few weeks, a near-perfect replacement grows. Do the same to a lizard and a new tail will regrow, but it won't be the same as the original. By comparing tail regeneration between the two ...
A trauma victim is wheeled into an emergency room, his thigh caked with blood-soaked bandages.
When sea creatures first began crawling and slithering onto land about 385 million years ago, they carried with them their body armor: scales. Fossil evidence shows that the earliest land animals retained scales as a protective ...
