MTT assay of KG1 cells with or without hiwi.

KG1 cells were subjected to transfection under 3 different conditions (control KG1, KG1+pCIneo, KG1+pCIneo-hiwi) and were cultured for a 9-day period. An MTT assay was performed on each day to assess cell proliferation from days 1 through 6 and then on day 9.
