These stem/progenitor cells are in vivo expanded as multicellular spheroids called mammospheres.
Two hypotheses have been proposed: 1) vascular damage with resultant blood--brain barrier breakdown and consequent ischaemia, resulting in oligodendroglial and axonal damage, including spheroid formation, and widespread loss of axons and myelin sheaths; and 2) abnormalities of systemic lipid metabolism, resulting in breakdown of the myelin sheaths.
