A mast cell is a special type of cell that acts like a white blood cell. It lives and works in the body's tissues, not usually in the bloodstream. Mast cells are made in your bone marrow. They finish growing in different tissues, where they help protect your body from tiny invaders like parasites.

What Are Mast Cells?
Mast cells are known for having many tiny storage sacs inside them. These sacs are called granules. These granules are full of important chemicals, like histamine and heparin. Histamine plays a big role in allergic reactions. Heparin helps prevent blood clots.
What Do Mast Cells Do?
Mast cells have several important jobs in your body. They are key players in wound healing. When you get a cut or scrape, mast cells rush to the area. They release chemicals that help the wound close and heal properly.
They also help defend your body against pathogens. Pathogens are things like bacteria, viruses, or parasites that can make you sick. Mast cells act as a first line of defense, sounding the alarm when they detect a threat.
Mast Cells and Allergies
While mast cells are very helpful, they can sometimes cause problems. They are a main reason why people have allergies. When someone with allergies comes into contact with something they are allergic to (like pollen or peanuts), mast cells can overreact.
They quickly release histamine and other chemicals. This release causes allergy symptoms like sneezing, itching, swelling, or a runny nose. In severe cases, mast cells can trigger a dangerous reaction called anaphylaxis. This is a serious, whole-body allergic reaction that needs immediate medical help.
How Mast Cells Were Discovered
Mast cells were first described by a scientist named Paul Ehrlich. He wrote about them in his doctoral paper in 1878. He noticed how large and colorful their granules looked when he stained them. Today, we know that mast cells are a very important part of your immune system. They constantly work to keep you healthy and safe.
