Changes in the number, proliferation rates, and bcl-2 protein immunoexpression of epithelial and periductal cells from rat epididymis during postnatal development
Basal cells cell proliferation
2009/2/18
To investigate 1) the correlation between the proliferative activity of epididymal epithelium plus myoid cells and the increase in the number of these cells and 2) the role of the basal epithelial c...
Androgen binding protein secretion and endocytosis by principal cells in the adult rat epididymis and during postnatal development
Androgen binding protein secretion endocytosis principal cells adult rat epididymis
2009/2/18
Androgen binding protein (ABP) has been shown to be secreted by Sertoli cells and to be actively taken up by the efferent ducts and proximal caput epididymidis and, yet, to be present at high concen...
Differential expression of clusterin in the testis and epididymis of postnatal and germ cell deficient mice
clusterin epididymis postnatal germ cell deficient mice
2009/2/16
Clusterin is found in a wide variety of tissues and is expressed in a number of physiological and pathological contexts. It is expressed constitutively in the adult male reproductive tract, specific...
Human chorionic gonadotropin but not the calcitonin gene-related peptide induces postnatal testicular descent in mice
Cryptorchidism mechanisms androgens paracnne factors gonadotropins testes
2009/2/13
The androgen-regulated paracrine factor, calcitonin gene-related peptide (CGRP), has been proposed as a possible mediator of testicular descent. This peptide has been found to increase rhythmic co...
Cell proliferation in the dorsal and lateral lobes of the rat prostate during postnatal development
Cell proliferation dorsal lateral lobes rat prostate postnatal development
2009/2/12
We have shown previously that cell proliferation occurs throughout the ducts of the rat ventral prostate during its postnatal development. Our objectives herein were to identify and quantify proli...
Expression and Regulation of Aquaporins 1, 8, and 9 in the Testis, Efferent Ducts, and Epididymis of Adult Rats and During Postnatal Development
channels Sertoli cells Leydig cells principal cells clear cells nonciliated cells
2008/12/30
Aquaporins (AQPs) are membrane protein channels that allow the rapid passage of water through an epithelium containing tight junctions. In the present study, light microscope immunocytochemistry ...
Acquisition of androgen-mediated expression of mouse vas deferens protein（MVDP）gene in cultured epithelial cells and in vas deferens during postnatal development
androgen-mediated mouse vas deferens gene cultured epithelial cells
2008/12/25
We used cultured vas deferens epithelial cells (VDECs) as a model system to determine the conditions that allow mouse vas deferens protein (MVDP) gene expression and acquisition of androgen responsi...
Stereological Quantification of Nerve Fibers Immunoreactive to PGP 9.5, NPY, and VIP in Rat Prostate During Postnatal Development
Innervation neuropeptides
2008/12/23
This work was undertaken to study prostate innervation during the postnatal development of rats. It deals with the quantification of nervous fibers throughout all the regions of the rat prostate durin...
Expression of the p63 and Notch Signaling Systems in Rat Testes During Postnatal Development：Comparison With Their Expression Levels in the Epididymis and Vas Deferens
Spermatogenesis p53 differentiation
2008/12/22
The role of tubular structures that contribute to the passage of spermatozoa is not solely passive; these structures actively contribute to their own functions, although these tubules and ducts ar...
Postnatal Development and Regulation of ß-Hexosaminidase in Epithelial Cells of the Rat Epididymis
Principal narrow clear basal cells lysosomes orchidectomy efferent duct ligation
2008/12/22
ß-Hexosaminidase (Hex) catalyzes the hydrolysis of terminal sugar residues from a number of substrates such as GM2 gangliosides, glycoproteins, glycolipids, and glycosaminoglycans. As an enz...
Effect of Transient Embryonic In Vivo Exposure to the Endocrine Disruptor Methoxychlor on Embryonic and Postnatal Testis Development
Sertoli mesenchymal-epithelial growth gametogenesis
2008/12/19
The current study was designed to examine the effects of a transient embryonic exposure to the pesticide methoxychlor, an endocrine disruptor, on in vivo rat testis development and function. Gesta...
