Cytochemical and cytogenetic findings in five human leukocyte long-term cultures (LAHL) of different origin.

Five human leukocyte long-term suspension cultures were investigated by means of cytochemical and cytogenetic methods. A striking resemblance in the morphology of these cells originating either from peripheral blood or from spleen of patients with or without hematological disorders was found. Lymphocytic origin of all five cultures is suspected.
