«This tells you that all the
different types of stromal cells in breast
tissue are affected by the GT198 mutation
because they all come from a common progenitor cell.»
So, at the dawn
of our universe — and I have to emphasize our universe,
because there could be others — so, dawn
of our universe, physicists think there was one
type of force, one
type of matter and that as the cosmos expanded, as space expanded, it cooled and things started to condense out like snow flakes, and over time that single force broke, it differentiated; and something similar happens in the human body as we develop from a single cell; we differentiate,
different tissues form in our bodies,
different layers
of tissues.
Because stem cells have the unique ability to develop into many
different types of cells, they are an important part
of the mechanism for repairing body
tissue.
