WNT7A inhibits cell proliferation in Jurkat cells. (A) Percentage of cell proliferation measured in Jurkat cells, Jurkat-pLVX (stable transduced with empty-vector), or Jurkat-pLVX-WNT7A cells after 48 h of culture. Percentages of cell proliferation were obtained by taking Optical density (OD) values of the Jurkat cells as 100% cell proliferation. (B) Leukemia-derived Jurkat cells and PBMC were exposed for 48 h to 3 μg/mL of recombinant human WNT7a (+rhWNT7a). Afterward, the percentage of cell proliferation was measured by employing WST-1 and setting the value of non-treated control cells (Jurkat and PBMC for their respective assays) at 440 nm as 100% of cell proliferation.
