In vitro immunological studies on east african cancer patients. III. Spontaneous rosette formation by cells from Burkitt lymphoma biopsies.
Spontaneous rosette formation was observed in eight out of nine Burkitt lymphoma biopsies. These were examined fresh and/or after culture in vitro for up to 48 h. The percentage of rosettes varied from 3.7% to 38%. There was a tendency for the percentage of rosettes to increase with time in tissue culture. It is suggested that the rosette-forming cells are T-lymphocytes infiltrating the tumour and functioning as a host defence mechanism against the proliferating tumour cells.
