Could humans ever build a Jurain treeship

[WaitoKon]

What the title says!

To elaborate, though, recently the 'Answers With Joe' video blogger populated my YT app, and sure enough a topic came up about scientists reworking from frog eggs a veritable stem cell assembly line. They could preprogram the cells even, with instructions to grow tissues that can perform various functions. This includes mechanical roles like pistons almost as sophisticated as miniature hearts. Even determining from day 1 what shape, consistency and color.

Now, with some tinkering, this could apply to another organic molecule but one way more spaceworthy.

So, how soon do you all think something on par with Jurain ships, sentience and all, be achievable?
