Probably 90 % of ceramide gathers at the top or apical end of these early stem cells, literally helping cells have direction. ‘We have cell polarity, an up and down, head and foot the cell, and that is what ceramide likely regulated,’says Dr. Bieberich. ‘Cell polarity is absolutely necessary for differentiation, otherwise you have a ball of cells, not organized tissue. ‘.Inc.
