The Cytotoxic And Kinetic Effects Of Asynchronous Cells Following The Administration Of Vincristine

Abstract

A growth curve was constructed for SCCVII-SF, a mouse squamous cell carcinoma cell line, in a culture of modified q-crle's medium. A toxicity curve was constructed for vincristine ,nd SCCVII-SF cells in the exponential phase of growth. Cells in mid-exponential phase were treated with a subtoxic level of vincristine for four hours. A count of mitotic cells was taken at intervals to determine whether vincristine caused a buildup of cells in mitosis after its removal. Results showed that cells continued to collect in mitosis for four hours after the removal of vincristine.
