Graph showing Tumor weight versus days since subcutaneous implant of the MOLT-4 tumor in SCID mice. There were two groups in the study. Group 1: 1x10^7 cells were implanted SC Bilaterally [Passage 1]. 80% Take Rate. Group 2: fragments implanted bilaterally- Passage 4. 100% Take Rate 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. P1 [Group 1] Notes: Ten animals were assigned to this group. Two animals in this group failed to establish tumor growth on the right side [take rate was adjusted to reflect these animals] - while only right tumor values were used for calculations, it is important to note that there was progressive tumor growth in the left tumors of these animals. P4 [Group 2] Notes: Nine animals were assigned to this group. The tumors tend to grow flat until ~ 10x10 mm, then the tumors start to become rounded.
