Morphology of OCLs induced by coculture of HPCs with ATL cells.
Giant multinucleated cells were observed when HPCs were cocultured with ATL cells from patients with hypercalcemia (cases 1 and 3). In contrast, such OCLs were not observed when HPCs were cocultured with ATL cells from patients without hypercalcemia (cases 10 and 15).
