Table 2.

Population composition can be shaped by manipulating resources

Ratio of splenocytes in the inoculum, SP6:MD4	Fraction of retrieved μa-ve cells of SP6 origin
	Without TNP-Ficoll	With TNP-Ficoll
50:50	0.3	0.5
	0.2	0.5
	0.3	0.6
10:90	0.05	0.1
	0.01	0.1
	0.02	0.4

As predicted, in the presence of their specific antigen the SP6-derived cells constituted a larger proportion of the cells of donor origin.
