It is now known that the increase in serine proteases blocks lamellar body
secretion, so the lipids become trapped in the corneocytes.

Hyaluronan-CD44 interaction stimulates keratinocytes differentiation, lamellar body
formation/secretion, and permeability barrier homeostasis.
Measuring the number of lamellar body

Round cells lack well-defined lamellar bodies, but instead display variably-sized electron-dense bodies that have been interpreted to represent different stages of lamellar body
