Sialoglycoconjugates in lipid droplets?

Using the mPA-TSC-SP staining procedure, it is possible to detect dense silver deposits in the marginal area of some morphological structures of the human oviductal epithelium. By reason of their pale grey homogeneous appearance, we suppose that they are lipid droplets. They probably contain sialoglycolipids lying at the rim of the droplets. The functional significance of the compounds is hitherto unknown.
