Scanning electron microscope study of herpes simplex virus experimental disciform keratitis.

Scanning electron microscopy of the endothelium of experimental disciform keratitis revealed corneal endothelial changes which distinguished disciform oedema from the more progressive stages of disciform keratitis. The endothelium of corneas with disciform oedema were wholly intact and characterised by subtle morphological alterations. In contrast, the more progressive stages of disciform keratitis were characterised by massive destruction and denudation of the endothelium. The significance of these observations is discussed.

Scanning electron microscopic observation of two retinoblastoma cell lines.

Two continuous retinoblastoma cell lines were observed by scanning electron microscopy. Both cell lines spontaneously grow as a suspension of round cells in clusters, chains, and unique ring (rosette) formations. Scanning electron microscopy of suspension cells reveals some variation in the number and frequency of surface adornments such as blebs, lamellipodia, and microvilli. Although the cell lines are nonadherent to substratum and therefore assume a spherical form, highly villous cells are not characteristic of the entire cell populations. When WERI-Rb1 and Y79 are seeded onto a polyornithine-treated substrate, attachment and growth as adherent cultures are evident. With selective attachment on a positively charged substrate, we observe alteration of membrane architecture with the extension of cytoplasm and filopidia. In addition, WERI-Rb1 cell-to-substratum adhesion induces morphological changes suggestive of neuronal cell differentiation.
