Morphometric ultrastructural evaluation of human peripheral blood T lymphocyte subpopulations isolated on the basis of their affinity for sheep red blood cells.
The present investigation were undertaken to compare on the basis of ultrastructural morphometric analysis human T lymphocyte subfractions forming rosettes with sheep red blood cells (SRBC). The following T lymphocyte subfractions were obtained: ARFC (active rosettes), T1RFC (rosettes after 1 h at 4 degrees C) and T2RFC (rosettes after 2 h at 4 degrees C). Analysis of the mean cell and nuclei volumes of lymphocyte subfractions led to the separation of two cell groups differing in volume in each donor: a cell group consisting of large cells (T1RFC) and group of small cells (ARFC and T2RFC).
