Table 1 Tumorigenicity of SP Cells in NOD/SCID Xenotransplant Assay

From: Compound Kushen Injection suppresses human breast cancer stem-like cells by down-regulating the canonical Wnt/β-catenin pathway

Cells injected/fat pad Tumors/injections
  5 × 106 1 × 105 1 × 104 1 × 103
Unsorted 6/6 5/6 5/6 3/6
SP --- --- 6/6 5/6
Non-SP --- --- 5/6 2/6
  1. Table showing the number of tumors generated in NOD/SCID mouse fat pads by SP, non-SP, and unsorted cells. Tumor formation by 1 × 104 cells was observed for 6 weeks after injection, whereas tumor formation by 1 × 103 cells was observed for 9 weeks after injection.
