WNTs promote cell proliferation in suspension cultures of flASK cells. The fold expansions in cell number after culture for 7 days are shown. Cultures were initiated with flASK cells (5,000/well), 25 ng/mL KL, and CM from 293 cells transfected with control plasmid, Wnt-1, Wnt-5a (gDWnt5aHis6 ), or Wnt-10b. Assays were performed in duplicate and repeated in two independent experiments.
