These studies are promising :

The accumulation of DNA mutations in some cells over time can cause cancer, (...)
It is a much greater challenge to sequence DNA from individual cells, because there are only two copies of the genome to work with, (...)

Okay, I'm super far from a biological/genealogical scientist. What's promising about that?

... impossible to say right now, yet, I look at this as a new paradigm. Like, instead of looking at the animal kingdom and saying they are all animals, being able to distinguish between many different species, but for the body : the previous understanding was that our cells had the same genetic code and now the Horizon widens to show a whole new diversity we didn't know about.
i believe it's the start of a new science.
