In stratum granulosum. Contain dense masses of filaggrin and other proteins that help crosslink keratin.
Membrane-coated lamellar granules
In stratum granulosum. Produce lipid-rich material that create water tight envelope across cells.
Microphthalmia-associated transcription factor
Master regulator of melanocyte development, function and survival. Arrests the cell cycle, turns on melanin-producing genes.
Eccrine sweat glands
In reticular layer of dermis. Cholinergic innervation, merocrine secretion.
In reticular dermis, usually as appendages of hair follicles (though there are hair-independent ones in lip, nipple, genital areas). Holocrine secretion.
Apocrine sweat glands
In hypodermis. Secretion of pheremones. Adrenergic innervation. Merocrine secretion.
