Graph showing Tumor weight versus days since subcutaneous implant of the K-562 tumor in SCID mice. There was one group in the study. Group 1: 1x10^7 cells were implanted SC Bilaterally [Passage 1]. 73% Take Rate. Notes: Fifteen animals were assigned to this group. Animals were bilaterally implanted for subsequent tumor collection and microarray studies. To ensure standardization in data reporting, only right tumor values were utilized for growth data associated with microarray studies. Two animals failed to maintain tumor growth at Day 11 post implant. The take rate reflects these animals.
