    An increased ability to repair DNA (e.g., by combating the deleterious effects of reactive oxygen species) is directly proportional to increased life span for a cell.
    The number of mitotic divisions that a cell can undergo is directly proportional to the shortening of the telomeres.
    Some "immortal" cancer cell lines have reproduced for decades while maintaining genetically identical cells, indicating that they have found a way to bypass the regulatory mechanisms in the life span of a cell.
    all of the above
