Once the sperm cell meets the egg cell and they form a zygote the program is triggered, coupled with the means for its realization and within a period of a few months (depending on an organism) with the help of only basic inflow of ingredients from the outside, we have a complete organism - baby, cub, whatever.
If we have the program and the 'factory' that knows how to produce each part of the organism (for it's done it once, can do it again), why regeneration is pretty limited to lizard's tails and stuff like that? Is it the 'program' or the production?

Well, it does seem a shame that human beings only grow two sets of teeth in a lifetime.....it would be a big improvement if we could just grow a new tooth when we needed one.

Yeah, a tooth, a limb...

I'm not sure I'm understanding the question. Are you asking why humans aren't capable of regenerating teeth, limbs, etc.?

Yes, I argue that the "blue prints" and the "production facilities" are within us, as everything we have was produced by our organism once in the process of the initial development from one cell and therefore can supposedly be reproduced again

It does seem that stem cells can be used to produce new organs, given the scientific technology to do so. What do you see as the time line for producing replacement organs?

I'd go for the nearest decade and with different biotech approaches: stem cells, 3-d printing, cloning
