The human body is a complex machine. When it breaks down, fixing it can be a long and difficult process. But what if doctors could just print out a new part right where it's needed? That's the idea behind in-situ bioprinting. It's like having a tiny 3D printer that can create new tissue or even orga
Scientists have created a special covering for a material that helps bones heal. This covering is made using a mix of gelatin and a mineral called carbonated hydroxyapatite. The goal is to make this material more like real bone tissue. To make it even better, they used a special process called plas
Fixing damaged joints is tough because they are made of different types of tissues. Think of it like building a bridge between two different materials. Scientists are working on special structures called bionic gradient scaffolds. These are like tiny, 3D bridges that help new tissue grow where it's
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
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 ha
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
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 comp
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. T
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 br
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 cr
