WebSTEROID-SECRETING CELLS are characterized by abundant smooth endoplasmic reticulum (SER). These cells synthesize cholesterol as a precursor for steroid hormones or take up this substrate from plasma lipoproteins. The ratio of synthesis to uptake is dependent on the species, cell type, and functional state (see Ref. 1 for recent review).
