Perhaps its an accumulation of certain constitutively produced enzymes and proteins to reach threshold over time?

Probably, but like many things it seems very hard to identify the actual trigger proteins / enzymes or whatever. It's fascinating to study but depressing how little we know.

Incidentally, I think the initial cell fusion that kicks off the growth process is equally interesting. We know some but not all of the protein interactions.
