Mecasermin

How it works

IGF-1 made by bacteria: the growth factor the liver releases on growth hormone's orders, for children who lack it and don't grow.

What it's made of

Human IGF-1 copied exactly: 70 amino acids with 3 sulfur bridges, made by bacteria. It is the hormone the liver produces when growth hormone reaches it.

What it's for

Prescribed for

Children aged 2 or older who do not grow because of a severe primary IGF-1 deficiency (such as Laron syndrome) or because they lack the growth hormone gene.
