An extensive study of the interactions between LAK-target cells in cocultures was performed by means of cytometric (relative DNA and protein content) and morphological parameters.

Specimens obtained from cocultures at 0, 24, 48 hours were processed for electron microscopy, flow cytometry, immunocytochemistry (anti-BrdU reaction) and light microscopy (L.I., M.I., cell-cell interaction).

Abstract
An extensive study of the interactions between LAK-target cells in cocultures was performed by means of cytometric (relative DNA and protein content) and morphological parameters. The aim was to obtain new information about the cell cycle stage of tumor target cells (Chang line) during the attack of LAK cells. Specimens obtained from cocultures at 0, 24, 48 hours were processed for electron microscopy, flow cytometry, immunocytochemistry (anti-BrdU reaction) and light microscopy (L.I., M.I., cell-cell interaction).
