To determine if maintained L-selectin alters the number of tumor infiltrating lymphocytes (TILs), the total numbers of CD3+ and CD8+ T cells were enumerated in tumor sections from solid tumors harvested at the end of the study (this could represent either an individual mouse culled due to tumor size, or animals sacrificed as a group at the end of the entire study). The gene discussed is SELL; the disease is neoplasm.
