There is an old paper from 2006 in Cell that was similar to this study in that it showed onencould direct stem cell differentiation down different lineages purely by growing the cells on different stiffness substrates.

I am guessing there is a reason for it.  Might be more applicable in severe MS than aging.</text></comment>
