Erythropoietin

/ɪˌrɪθroʊˈpɔɪətɪn/noun

A hormone released by the kidneys that drives the marrow to produce red blood cells.

The Greek roots

ἐρυθρός
erythrós
red
+
ποιεῖν
poieîn
to make, produce

Literally: red-maker

The story of the word

Two Finnish physiologists, Eva Bonsdorff and Eeva Jalavisto, named the substance in 1948, long before anyone could purify it. The second root is the same ποιεῖν that gives poetry its name, so a poet and this hormone are both, literally, makers. Recombinant versions reached the clinic in the late 1980s for kidney patients and were in professional cycling within a few years.
