Abstract
IL-6 was demonstrated to promote growth of EBV transformed lymphocytes. However IL-6 was ineffective at promoting growth of EBV transformed lymphocytes cultured at the single cell level under limiting dilution conditions. On the contrary, HECS, which is known to contain IL-6, supported very efficiently the growth of 1–2 EBV transformed cells. When IL-6 was removed from HECS, by using specific antibodies, no reduction in HECS activity was observed, indicating that probably more than one growth factor is required to support the growth of EBV transformed cells cultured at very low cell numbers in the absence of feeder cells.
