Evidence is accumulating that suggests that cancer cell clusters are more likely to lead to metastatic lesions than are single cells. This mini-review explores this issue by examining evidence that indicates that cell clusters possess altered genes and metabolism that promote metastasis. When clusters are disaggregated, the resulting single cells often lose the altered properties characteristic of when they were in clusters. When cluster disrupting agents were injected into mice, metastasis was reduced. Cluster disaggregating agents are described and mechanisms of action of these compounds are explored. Using these agents to target cell clusters might offer a useful therapeutic approach in the treatment of cancer. Cell clusters are also involved in thrombocytosis and biofilm infectivity as well as cancer spread and cluster disrupting agents might be very useful in treating some human conditions in addition to cancer spread. Assays that examine the effectiveness of cluster disrupting agents are also described.
