  1. a, axillary; c, cervical; CD, cluster of differentiation; DP, double positive; I, inguinal; LN, lymph node; m, mesenteric; md, mediastinal; SP, single positive.
  2. A phenotype was assigned based on the cell surface expression profile with null relating to those tumours that were negative for all lineage defining markers (CDs 3, 4, 8 and B220). A representative set of 10 tumours for each genotype are shown. Where a cell surface protein is not mentioned in the table, it was not expressed on the tumour cells (of CDs 4, 8, 25, 44, 117, 30 and Vα2).
