U.S. scientists have discovered embryonic stem cells like to be
gently shaken or sloshed, much in the same way they are in a mother's
womb.
Georgia Institute of Technology and Emory University researchers said
such shaking significantly improves embryonic stem cell development
and might some day even be used to control what type of cell they
eventually become.
Student researcher Rich Carpenedo discovered placing embryonic stem
cells in vitro on the lab's shaker plate created healthier and more
uniform clusters of differentiating cells. The researchers
subsequently found cell development could be controlled with
different types of "sloshing" movement.
"Embryonic stem cells develop under unique conditions in the womb,
and no one has ever been able to study the effect that movement has
on that development process," said Georgia Tech and Emory Assistant
Professor Todd McDevitt, who led the project. "While labs typically
add all sorts of things to their cultures to influence cell
direction, we were able to control the levels of differentiation and
size of cell clusters by simply providing some fluid motion."
The research appears in the September issue of the journal Stem Cell
