As expected, PDX01, PDX02, and PDX03 exhibited low percentages of tumor-infiltrating human CD8+ T lymphocytes and high percentages of tumor-infiltrating human CD133+ CSCs, whereas PDX04, PDX05, and PDX06 exhibited high percentages of tumor-infiltrating human CD8+ T lymphocytes and low percentages of tumor-infiltrating human CD133+ CSCs (Figure 5F–5I). The gene discussed is CD8A; the disease is neoplasm.
