Progenitor cells are a special kind of cells in our body that have the ability to develop into different types of cells. They act as building blocks, giving rise to more specific cells that make up tissues and organs. Think of them as cells with potential, like the ingredients that can turn into various dishes when cooking.
Progenitor cells play a crucial role in the growth, repair, and maintenance of our body.
