Could we see #174 with a just a tiny bit more space between the mark and "MITOKININ"?
Also, I'd be curious to see your design motif (the three ovular 'pills') inside a large pill oriented sideways. It might prove an interesting abstraction of mitochondria!
The big boss likes your logo... so you're now the front-runner! The only thing I'd still like to see is a version of #249 without the rounded vertices (ie, with hard angles).
