An uninitiated reader might construe this as meaning that the
researchers more or less created a mouse from scratch. But it's clear
that that's not what happened. Rather, they've taken a non-stem cell
from a mouse and created a mouse stem cell from it.

I chased down the underlying article, which was unlocked for all.  The
article made sense.  I think the problem with the Science Daily
article is that the writer had no idea what they were looking at.

What was done is that an ancient functional piece was installed in a
modern mouse egg replacing the modern descendent of that piece, and it
still worked normally in the resulting mouse pup.  This piece is quite
ancient, and yet has remained essentially unchanged to this day.
