Scientists have created a clever tool to help repair heart valves in people with diabetes. This tool is a special kind of scaffold that mimics how the body naturally heals itself. The scaffold is made with tiny particles of iridium and ruthenium, which work together to balance out harmful chemicals in the body. When someone has diabetes, their body doesn't heal as w...
Scientists have made a big step forward in healing soft tissues. They created a special gel that can be 3D printed. This gel is made from a protein that acts like collagen, a key part of our skin and other soft tissues. The gel is special because it forms under normal conditions. It doesn't need harsh chemicals or external triggers. Instead, it uses a natural reacti...
Heart problems are a big deal worldwide, so scientists are working hard to find better ways to fix them. They're using special materials and high-tech methods to create parts that can help hearts work better. One big challenge is picking the right stuff to help heart cells grow and work well. There are two cool techniques being used. One is 3D printing, which can ma...
Dental pulp stem cells (DPSCs) are a key player in the world of regenerative medicine. They are easy to access and can transform into various cell types. This makes them perfect for creating three-dimensional (3D) models, known as organoids. These organoids are a big deal because they mimic the complexity of real tissues much better than the old flat (2D) cultures. T...
Cartilage repair is a tough job. Why? Because cartilage does not have blood vessels or cells. This makes it hard for the body to fix itself. But there is hope. Scientists are working on a solution using injectable hydrogels. These are like tiny, flexible sponges that can be injected into the body. They have shown great promise in helping cartilage grow back. Injecta...
The body's tissues are built tough, thanks to collagen. Collagen fibers run in specific directions, giving tissues their strength and stability. Scientists have been trying to copy this design. They have had a hard time making models that match the size and direction of natural tissues. Now, a breakthrough has been made. Scientists created new collagen tissues. ...
Imagine trying to build something with a material that keeps shrinking. That's a big problem in tissue engineering. Scientists have been using collagen-based hydrogels, which are great for growing cells, but they have a nasty habit of shrinking when cells interact with them. This makes it hard to create stable structures for things like drug testing or even growing n...
Building bones from scratch for medical needs is a hot topic in science. 3D printing is a big deal in this field. It's all about creating materials that match real bone tissue. This is tricky because bones have a complex structure. Scientists are exploring new ways to make this happen. Imagine printing bone structures that are as intricate as a spider web. T...
Burns can be a real challenge to treat. But scientists have come up with a clever solution inspired by nature. They've created a special gel that helps wounds heal faster. This gel is made from chitosan and silk fibroin, with a touch of tannic acid and riboflavin, which helps it stick well to the skin. It has two layers: the top one is filled with tiny holes to help ...
When it comes to growing new bones, scientists are exploring how to design the best scaffolds for the job. These scaffolds need to be good at helping new bone grow and strong enough to hold up. Researchers have looked at different types of materials, like metals, non-metals, and polymers, to make these scaffolds. They've also considered different ways to make these s...
