FILGRASTIM, G-CSF (fil GRA stim) is a granulocyte colony-stimulating factor that stimulates the growth of neutrophils, a type of white blood cell (WBC) important in the body's fight against infection.
The hypothalamus, a part of the brain, is responsible for many hormones. Understanding these brainy hormones will help you take control of your body and your health. The hypothalamus produces hormones that control the production of hormones in the pituitary gland.
The pituitary gland is often called the master gland because it controls several other hormone glands in your body, including the thyroid and adrenals, the ovaries and testicles. It secretes hormones from both the front part (anterior) and the back part (posterior) of the gland. Hormones are chemicals that carry messages from one cell to another through your bloodstream. If your pituitary gland is not producing sufficient amounts of one or more hormones this is called hypopituitarism.
