Meaning and Definition
A group of peptides, primarily produced in the liver, that mediate the growth-promoting effects of growth hormone (somatotropin) on tissues.
Now more commonly known as insulin-like growth factors (IGFs), they are part of a complex system that regulates cell growth, development, and metabolism.

FAQ
Frequently Asked Questions
No. Growth hormone (somatotropin) is secreted by the pituitary gland. Somatomedin (IGF) is produced mainly by the liver and other tissues in response to growth hormone and mediates its effects.
The discovery that these factors are structurally and functionally similar to insulin led to the more precise and widely adopted name 'insulin-like growth factors' (IGFs).
Primarily in historical medical literature, some older textbooks, or in discussions of the classic 'somatomedin hypothesis' of growth hormone action.
The substance itself (as IGF-1) has therapeutic uses in specific conditions like severe IGF-1 deficiency, but it is referred to by its modern name, not as 'somatomedin'.
A group of peptides, primarily produced in the liver, that mediate the growth-promoting effects of growth hormone (somatotropin) on tissues.
Somatomedin is usually technical/scientific (medical, endocrinology, biochemistry) in register.
Somatomedin: in British English it is pronounced /ˌsəʊ.mə.təʊˈmiː.dɪn/, and in American English it is pronounced /ˌsoʊ.mə.toʊˈmiː.dɪn/. Tap the audio buttons above to hear it.
Learning
Memory Aids
Mnemonic
Think: SOMATO (body) + MEDI (to mediate) + IN (a substance/chemical). It's the substance that mediates growth hormone's effects on the body.
Conceptual Metaphor
Somatomedin acts as a 'messenger' or 'middleman' for growth hormone.
