Tissue scaffold

A tissue scaffold is like a tiny structure made out of a special material. It looks like a very small ladder. It helps scientists grow new tissue in a lab. Scientists put a few cells on the scaffold. They might even put other things like growth factors or nutrients on it. Then, when the cells are all settled, scientists put the scaffold into a special container with other things that help the cells grow. Over time, the cells grow on the scaffold and it forms a new piece of tissue. This can help scientists study the tissue and find out how it works.
