The analysis of leucocyte population in human semen could be useful in the diagnosis and therapeutic monitoring of male genital infections, but it is difficult due the low percentage of leucocytes, often not easily recognizable from immature cells of spermatogenesis. A method was developed for the isolation and identification of different leucocyte populations in human semen in healthy subjects using anti-CD45-covered magnetic beads. The seminal fluid was incubated with anti-CD45-covered magnetic beads and the samples were placed in contact with a magnet. The CD45-positive cells recovered were analyzed by light microscopy. The leucocyte formula was compared with a leucocyte formula performed on seminal fluid sediment. The method, even if laborious, eliminates all spermatozoa and most of cells of spermatogenetic lineage, thus permitting phenotyping and functional analysis on isolated leucocytes.

D005434 Flow Cytometry Technique using an instrument system for making, processing, and displaying one or more measurements on individual cells obtained from a cell suspension. Cells are usually stained with one or more fluorescent dyes specific to cell components of interest, e.g., DNA, and fluorescence of each cell is measured as it rapidly transverses the excitation beam (laser or mercury arc lamp). Fluorescence provides a quantitative measure of various biochemical and biophysical properties of the cell, as well as a basis for cell sorting. Other measurable optical parameters include light absorption and light scattering, the latter being applicable to the measurement of cell size, shape, density, granularity, and stain uptake.

D017493 Leukocyte Common Antigens High-molecular weight glycoproteins uniquely expressed on the surface of LEUKOCYTES and their hemopoietic progenitors. They contain two FIBRONECTIN TYPE III DOMAINS and possess cytoplasmic protein tyrosine phosphatase activity, which plays a role in intracellular signaling from the CELL SURFACE RECEPTORS. Leukocyte common antigens occur as multiple isoforms that result from alternative mRNA splicing and differential usage of three exons.
