Cell culture assay

A cell culture assay is when scientists take special cells from an animal or human body and grow them in a dish so they can study how they work. They use a special formula that has all the nutrients these cells need to grow and keep them healthy. It's like how your mom or dad gives you food and water to keep you healthy.

The scientists will add different things to the cells to see how they react. It's kind of like adding different ingredients to a cookie mix and seeing what kind of cookie comes out. They might add medicine to see if it kills the cells, or they might add a chemical to see if it makes the cells grow bigger or smaller.

The scientists can learn a lot from these cell culture assays. They can learn about how cancer cells grow and what kinds of treatments might be able to stop them. They can also test new medicines to see if they are safe and effective before giving them to people.

Overall, a cell culture assay is like having a mini science lab in a dish, where scientists can study cells and learn more about how our bodies work.
