Organogenesis of the exocrine gland.
Morphogenesis of exocrine glands is a complex stepwise process of epithelial ingrowth, ductal elongation, ductal branching, and alveolar or acinar differentiation. Emerging from an increasing number of mouse gene knockout, dominant-negative, and antisense models is the identification of a remarkable collection of cell adhesion molecules, growth factors, and their receptors whose time-dependent ...
متن کاملExocrine Gland Dysfunction in MC5-R-Deficient Mice: Evidence for Coordinated Regulation of Exocrine Gland Function by Melanocortin Peptides
The effects of pituitary-derived melanocortin peptides are primarily attributed to ACTH-mediated adrenocortical glucocorticoid production. Identification of a widely distributed receptor for ACTH/MSH peptides, the melanocortin-5 receptor (MC5-R), suggested non-steroidally mediated systemic effects of these peptides. Targeted disruption of the MC5-R produced mice with a severe defect in water re...
متن کاملThe subepithelial gland in ants: a novel exocrine gland closely associated with the cuticle surface
Two glandular systems were discovered that secrete their products onto the cuticular surface in ants. The first, the subepithelial gland, was previously undescribed in ants, and is found throughout the body just beneath the epithelium. This gland consists of independent secretory units, each made up of a single gland cell and an associated duct cell that penetrates the cuticle. Its ultrastructu...
متن کاملKinetic analysis of rat exocrine gland muscarinic receptors in vivo.
Recently we employed two enantiomers of the muscarinic antagonist quinuclidinyl iodobenzilate (IQNB), and pharmacokinetic analyses, to define and quantitate nonspecific and specific binding to rat parotid gland muscarinic acetylcholine receptors (mAChRs) in vivo (Hiramatsu et al., 1993). The present studies were designed to utilize this same approach for evaluating mAChRs in three other morphol...
متن کاملA sulfated proteoglycan is necessary for storage of exocrine secretory proteins in the rat parotid gland.
Sulfated proteoglycans have been proposed to play a role in the sorting and storage of secretory proteins in exocrine secretory granules. Rat parotid acinar cells expressed a 40- to 60-kDa proteoglycan that was stored in secretory granules. Treatment of the tissue with the proteoglycan synthesis inhibitor paranitrophenyl xyloside resulted in the complete abrogation of the sulfated proteoglycan....
