Role of plasma factors in the transformation of peripheral blood lymphocytes into lymphoblasts

Eosinophilic response in glioblastoma tissue culture after addition of autologous lymphocytes

In experiments designed for the study of interactions in vitro between the cells of glioblastoma multiforme and lymphocytes from the same donor, a marked eosinophilic response was noted in three out of six cases. This was an entirely unexpected finding since few, if any, eosinophils survive in tissue cultures. These cells incorporated (3)H-cytidine and (3)H-leucine 72 hours after the cultures had been established, an indication that they were metabolically active.
