THE INTERSTITIAL GLAND

Interstitial gland tissue of mammalian ovary.

Heterogeneity of Ovarian Theca and Interstitial Gland Cells in Mice

It has been established that two developmentally and functionally distinct cell types emerge within the mammalian testis and adrenal gland throughout life. Fetal and adult types of steroidogenic cells (i.e., testicular Leydig cells and adrenocortical cells) develop in the prenatal and postnatal period, respectively. Although the ovary synthesizes steroids postnatally, the presence of fetal-type...

Histochemical observations on the lipid changes in the ovarian interstitial gland tissue of rats.

Lipid changes were studied histochemically in the ovarian interstitial tissue of untreated and hormone-treated rats during the oestrous cycle, pseudopregnancy, pregnancy and lactation. The hormones tested were LH, prolactin and oestradiol benzoate, alone or in combination. Conspicuous lipid changes occurred only in response to LH.

Immunohistochemical and ultrastructural study of interstitial cells during postnatal development of the sheep pineal gland

*Address correspondence to: Sergio Regodón. Departments of Embryology and Histology, Faculty of Veterinary Medicine, University of Extremadura, 10071 Cáceres, Spain. e-mail: [email protected] The pineal originates as an outgrowth of the roof of the diencephalon in all vertebrate species. This evagination arises between the habenular commissure anteriorly (or rostrally) and the posterior commissure...

The role of interstitial collagens in cleft formation of mouse embryonic submandibular gland during initial branching.

An interstitial collagenase was purified from the explant medium of bovine dental pulp and was shown to degrade collagens I and III but not IV and V. The enzyme halted cleft initiation in the epithelium of 12-day mouse embryonic submandibular glands in vitro, indicating the active involvement of interstitial collagens in the branching morphogenesis. Transmission electron microscopic observation...
