Mounting evidence suggests that the pre-TCR does not require interaction with a ligand to perform its function, and the subsequent CD44 -25 -(TN4 or pre-DP) to DP transition has been termed "programmed differentiation" to indicate that this step can occur in isolated thymocytes, presumably without input from extrinsic signals [ 25 26 27 ] . However, there is also evidence that the thymic microenvironment does contribute signals required for the TN-DP transition, particularly to promote thymocyte proliferation and apoptosis [ 13 28 29 30 ] . The specific nature and purpose of the TEC contribution during this important transition therefore remains to be determined.
If so, the extrinsic factors should be viewed as inducers and intrinsic factors as effectors of asymmetric division.
Previously, we identified correlations between large-scale variation in winter climate, the North Atlantic Oscillation (NAO) [ 9 ] , and: predation efficiency of wolves ( Canis lupus ), mortality of old moose ( Alces alces ), and growth dynamics of balsam fir ( Abies balsamea ) on Isle Royale [ 6 ] . Additionally, we have documented influences of the NAO, wolf predation, and density dependence on the intrinsic rate of increase in the moose population on Isle Royale [ 10 ] . Hence, the current analysis was motivated by the results of these earlier attempts to dissect the relative contributions of intrinsic and extrinsic processes to the dynamics of this community, as well as by a more general interest in developing a community-level model of climatic effects at and among multiple trophic levels that may subsequently contribute to our understanding of the implications of climatic change for community stability.
Cells grown in culture have unlimited access to nutrients under conditions most favorable for growth and proliferation and little exposure to extrinsic factors such as cytokines that modulate growth and differentiation.
In other words, asymmetric division in vivo may be a result of the influence of both extrinsic and intrinsic factors.
