    Abstract: This invention relates to methods and means for the stimulation of phagocytosis and in particular to the phagocytosis of apoptotic cells, and discloses a role for the protein product of the apoE gene (apolipoproteinE) as a regular of apoptotic cell clearance. ApoE mimetics and other compounds which stimulate the clearance of apoptotic cells may be useful in the treatment of a range of disorders. One aspect of the invention provides a method of identifying and/or obtaining a compound for the treatment of a condition associated with decreased endogenous apoE activity in an individual comprising: determining the ingestion of apoptic cells by a macrophage in the presence of a test compound. An increase in apoptic cell ingestion in the presence relative to the absence of test compound may be indicative that the compound may be useful in the treatment of a condition associated with decreased endogenous apoE activity.

The phenotype may be established as a "snapshot" of the cells at a particular time or it may be established as a variation in features over time, or as some combination of these "static" and "dynamic" characterizations. The phenotype may be characterized by at least the following features: (a) chromosomes that approach metaphase but fail to separate and maintain alignment compared to a control cell or cell population; (b) a bipolar spindle that is at least about 10% longer than a corresponding metaphase mitotic spindle from the control cell or cell population; and (c) during interphase the cell or population of cells exhibits a phenotype that is substantially similar to that of the interphase cells of the control cell or cell population.
