Electron microscopic observations of concentric lamellar bodies within mesenchymal cells of anagen hair dermal papilla.
The presence of 2 forms of the concentric lamellar bodies was observed in the mesenchymal cells within dermal papilla of normal scalp anagen hairs. They are those composed of agranular membrane arrays in association with beta-glycogen particles (glycogen bodies) and those of smooth-surfaced endoplasmic reticulum (smooth-surfaced lamellar bodies). On rare occasions these 2 forms of the concentric lamellar bodies were simultaneously present within the same cells. Transitional forms between the smooth-surfaced lamellar bodies and phagosegresomal granules were also encountered.
