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
People die every day because there aren't enough organs for transplants. This is a big problem. Doctors have a new idea to fix this. They want to use special inks and stem cells to print organs with a machine. This could be a game-changer. But it's not that simple. There are lots of questions to ans
The quest to mend damaged cartilage has led scientists to explore the power of 3D printing and stem cells. This isn't just about printing ink on paper. It's about using a special kind of ink made from natural materials and living cells. The goal is to repair cartilage, the smooth, white tissue that
The need for organ transplants and accurate tissue models has pushed the field of tissue engineering into the spotlight. This area focuses on creating tissues and organs outside the body, which is crucial for regenerative medicine. One exciting development is the creation of artificial intervertebra
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
Creating lifelike tissue structures for medical purposes is a big challenge. Scientists are trying out new methods like using self-healing fluids to help in this process. One interesting way is using gellan gum to form little gel balls, called granular gels. These are made by stirring during gel for
