AbstractThe stroma-vascular fraction (SVF) of adipose tissue (AT) is a heterogeneous cell fraction composed of progenitor cells, endothelial cells, and immune cells. SVF plays a key role in AT homeostasis and growth as well as in obesity-associated pathologies. The SVF cell composition and phenotype are distinct according to AT location and adiposity. Such discrepancies influence AT function and are involved in obesity-associated disorders such as chronic inflammation. Investigations performed in recent years in rodents and humans provided evidence that the stroma-vascular cells contribute to the conversion of steroid hormones in AT and are also steroid targets. This review describes the link between steroids and SVF depending on gender, adiposity, and AT location and highlights the potential role of sex and corticosteroid hormones in adipogenesis, angiogenesis, and their contributions in AT inflammation.

Adrenal Cortical Cells

Adrenal steroids are normally synthesized from acetyl coenzyme A via cholesterol. Cholesterol is also shown to enter the adrenal gland and to be localized in the lipid droplets of the adrenal cortical cells. Both pregnenolone and progesterone act as intermediates in the conversion of cholesterol into steroid hormones. During pregnancy an increased level of plasma cholesterol is known to be associated with an increase of the adrenal corticoid and progesterone. The present study is designed to demonstrate whether the adrenal cortical cells show any dynamic changes during pregnancy.

Transmission Electron

Smooth endoplasmic reticulum (SER) is involved in the biosynthesis of steroid hormones, and changes in the organisation and abundance of this organelle are regularly used as indicators of changes in the level of steroidogenesis. SER is typically arranged as a meshwork of anastomosing tubules which, with the transmission electron microscope, appear as a random mixture of cross, oblique and longitudinal sections. Less commonly the SER appears as swollen vesicles and it is generally suggested that this is an artefact caused during immersion fixation or during immersion of poorly-perfused tissue.During a previous study of the Leydig cells of a seasonally reproducing bat, in which tissue was fixed by immersion, we noted that tubular SER and vesicular SER often occured in adjacent cells and sometimes in the same cell, and that the abundance of the two types of SER changed seasonally. We came to doubt the widelyheld dogma that vesicular SER was an artefact of immersion fixation and set out to test the hypothesis that the method of fixation does not modify the ultrastructure of the SER.
