The part that caught my eye was:

Sounds like somatic cell therapy to me. Granted, they are working on engineered animals for protein production, certainly a more near-term (if you will pardon the expression) "cash cow" than human therapy.

Yep, that's a tough one.

Hey! Richard's from my home town. I've met him. Nice guy, treats his mother well. Just glad he lost those red-white-blue shorts. :)
Somehow, I think Chromos probably has some other approach in mind.

They never are, are they? For the really good stuff, anyhow.
The only downer in the release was:

Wimps. Fortunately, they aren't the only ones working in this field.
