Structures indicative of keratinization in lactating cells of bovine mammary gland
Abstract:
Keratohyalin granule-like aggregates and tangles of filaments similar to epidermal prekeratin fibrils have been observed in lactating cells of bovine mammary epithelium. The concomitant occurence of such structures, which are characteristic of early stages of keratinization, with typical secretory products such as casein micelles demonstrates that keratinization can take place in functional secretory cells. The observations are discussed in relation to current concepts of keratinization in epidermal and in non-epidermal epithelia.

Exocrine Glands: Methods of Secretion
Merocrine Secretion
Merocrine secretion is the most common type of exocrine secretion. The secretions are enclosed in vesicles and moved to the cell's apical surface, where the contents are released by exocytosis. For example, mucous, a watery secretion rich in the glycoprotein mucin, is a merocrine secretion. The eccrine glands...
Cells of the Epidermis
The cells in all these layers except the stratum basale are called keratinocytes, a type of cell that manufactures and stores the protein keratin. The keratinocytes in the stratum corneum are dead and regularly slough away, being replaced by cells from...
Papillary Dermis
The dermis might be considered the "core" of the integumentary system, as distinct from the epidermis and hypodermis. It contains blood and lymph vessels, nerves, and other structures, such as hair follicles and sweat glands. The dermis is made of two layers of connective tissue that comprise an interconnected mesh of elastin and collagenous fibers, produced by fibroblasts.
Papillary Layer
The papillary layer is made of loose, areolar connective tissue, which means the collagen and...
