title: Heparin effects on cultured mammalian cells.
abstract: Plasmacytoma cells exposed to heparin exhibited zeiotic blebs in the G1 phase, S phase, and early G2 phase. Zeiosis was not seen in mitotic cells. This heparin effect was reversible. Also fibroblasts were sensitive to heparin. After trypsinization of fibroblasts, heparin produced large non-reversible zeiotic blebs in the cells, except in those in mitosis. The primary target for heparin is apparently to be sought among components of the cellular periphery.
