Materials such as poly(ε-caprolactone) are used as scaffolds in bone tissue engineering, but their inherent hydrophobicity and surface smoothness can impair cell attachment, proliferation and differentiation in the lab, or ...
Researchers have succeeded in converting human skin cells into blood stem cells in an international collaboration project. "This is a first step on the way to generating fully functional blood stem cells in a petri dish which, ...
EPFL researchers have developed a hydrogel – made up of nearly 90% water – that naturally adheres to soft tissue like cartilage and the meniscus. If the hydrogel carries repair cells, it could help damaged tissue to heal.
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 ...
