The effects of the phorbol ester 12-O-tetradecanoyl phorbol-13-acetate on morphometric and stereological parameters have been studied using the HL-60 cell line as a differentiation model for the monocytic pathway. Evaluation of the differentiation was carried out by quantification of endoplasmic reticulum, Golgi apparatus, mitochondria and cytoplasmic granules. Changes in both nuclear and cytoplasmic volumes during TPA-induced differentiation led to a decrease of the nucleus-cytoplasmic ratio after 3 days of treatment. Plasma membrane glycoprotein pattern was also determined. The major change in cell surface was the presence of high amounts of glycoproteins containing N-acetyl glucosamine residues that make wheatgerm agglutinin lectin a valuable marker of the monocytic differentiation pathway in HL-60 cells.

D008854 Microscopy, Electron Microscopy using an electron beam, instead of light, to visualize the sample, thereby allowing much greater magnification. The interactions of ELECTRONS with specimens are used to provide information about the fine structure of that specimen. In TRANSMISSION ELECTRON MICROSCOPY the reactions of the electrons that are transmitted through the specimen are imaged. In SCANNING ELECTRON MICROSCOPY an electron beam falls at a non-normal angle on the specimen and the image is derived from the reactions occurring above the plane of the specimen. Electron Microscopy
