Re: Embryonic Cow Cells to Create Kidney-Like Organs

Reading the article, I wondered how much time is needed to grow such
kidney. In this instance, they waited a lot in the embryonic
development, and then they transplanted (sort of, as they did not
function as kidneys) micro-kidneys. So growing them fully might be
quite long, difficult to accelerate, and so might imply important care
and costs ?

Anyway like Jeff I am pleasantly surprised at how "easy" it seems ;
the impression is that with proper genetic material (through cloning),
things work smoothly and with high tolerance. It's not so "brittle",
it wants to work.
