Fig. 1.

Transferred arthritis incidence in recipient rats, illustrated as incidence (%) curves. Black line represents rats receiving inguinal lymph node cells, and dotted grey line represents rats receiving cells originating from the axillary/brachial lymph nodes. Number of rats receiving cells from inguinal lymph nodes are 9, 15, 8 and 8 for day 5, 8, 11 and 14, respectively; and the number of rats receiving cells from axillary/brachial lymph nodes are 3, 6, 4 and 4 for day 5, 8, 11 and 14, respectively. At day 8, the incidence was significantly higher in the group of animals receiving inguinal lymph node cells compared to animals receiving axillary/brachial lymph node cells (P < 0·05, Fischer's exact test).
