Immunol. 10: 556-561, 1980. PubMed: 6157544 TK1 cells have a unique phenotype with high levels of the lymphocyte integrin, alpha 4, beta 7.
They bind constitutively to the murine mucosal vascular addressin, MAdCAM-1. Ref

The cells are CD8 positive; they display approximately 1% of L-selectin of that expressed by normal lymph node cells.
