[Ultrastructural characteristics of immunologic subvariants of acute T-cell lymphoblastic leukemia].

Ultrastructural comparison was conducted between different immunological subvariants of T-cell acute lymphoblastic leukemia (T-ALL). Using the panel of monoclonal antibodies the cases of T-ALL were categorized into the following subvariants (early-T-, mature-T- and mature, activated-T-cell ALL). It has been shown that cells of these subvariants differ from each other in their ultrastructure and at the same time they reflect the submicroscopic features of corresponding normal counterparts.
