Abstract
Emerging evidence indicates that thymocyte self-renewal induced by progenitor deprivation carries an oncogenic risk that is modulated by intra-thymic competition from differentiation-committed cells. Here we discuss formative studies demonstrating that, in mice, early thymocytes acquire self-renewing potential when thymic progenitor supply is sub-physiological and the importance of cellular competition with this at-risk cell population to prevent lymphoid malignancy. We also consider the possibility that increased thymic residency time, established under conditions of limited cellular competition, may have contributed to oncogenesis observed in early SCID-X1 trials when combined with insertional activation of proto-oncogenes such as LMO2.
