title: Regulation of growth of an interleukin 2 (IL-2)-dependent murine T-cell clone (HT-2) in a defined serum-free medium.
abstract: In this study, we demonstrate that an IL-2-dependent T-cell clone (HT-2) can be grown in a serum-free medium (HB101) with defined additives at rates comparable to those which can be obtained in serum-containing medium. Further, we show that cells cultured in the serum-free medium in the absence of IL-2 arrest growth in the G1 portion of the cell cycle, and that these arrested cells can be stimulated to reenter the cell cycle upon the addition of IL-2 to the culture medium. Growth of these cells in the absence of serum requires the presence of IL-2 as well as other hormones and growth factors and 2-mercaptoethanol. HT-2 cells have been grown continuously in the serum-free medium for periods of up to 1 month.
