some android bred in a vat

[jacdac]

His thick-fingered hands were pale pink and utterly hairless, as were his wrists to his shirt cuffs, smooth as rubber, seemingly boneless, repellent. Like the hands of some android bred in a vat.

Context: The excerpt describes Jimmy Radburn, a black hat hacker operative, as thought out by Jane Hawk.

What is your interpretation of the bolded metaphor?

Gloss:
android: (in science fiction) a robot with a human appearance. [as modifier] • there were no android security guards to stop him.
vat: a large container for holding or storing liquid

Thank you.

Those definitions pretty-much answer your question. I would just change “bred” to “created”.
