Comparative immunophenotypic characterization of human and monkey permanent lymphoid culture cells

: The aim of the study was to define the comparative immunophenotypic characteristics ofwidely spread lymphoid cell cultures, derived from Burkett's lymphoma named as Raji and P3HR-1 in comparison with analogous monkey cultures. It has been shown that P3HR-1 culture consists of similar type cells - activated B-lymphocytes CD23 with k phenotype, which demonstrates its monoclonality. Raji culture includes cells with markers of immature B-lymphocytes CD10 and CD24, as well as elements expressing CD10 antigens. T-cell markers were found in none of the cultures. In contrast to human cells, monkey lymphoid culture expressed both B- and T-cell markers. Moreover, in one of them, obtained from a green monkey, T-cells of suppressor type (CD8) prevailed. The immunophenotypic characteristics of primate lymphoid cell cultures, revealed by the study, are of great importance for their proper application to medical and biological studies.
