What is G-CSF?
G-CSF is a special type of protein called a growth factor. It stimulates the bone marrow to make white blood cells. The bone marrow is a spongy material inside the bones where all of our blood cells are made.
Growth factors are made naturally in the body. They can also be made outside the body and used as treatments.
There are three different types of G-CSF that can be used:
- lenograstim (Granocyte®)
- filgrastim (Neupogen®, Nivestim®, Ratiograstim®, Zarzio®)
- pegylated filgrastim (Neulasta®).
These treaments all work in similar ways.
