Fig. 7. L- and S-endoglin modify cell proliferation. (A) Proliferation was assessed by the number of cells determined by MTT assay. Cell proliferation was analyzed at day 0 (day of treatment, data not shown) and 3 days after treatment. A representative experiment of three independent experiments using quadruplicate samples is shown. (B) Representative flow cytometry graph showing a higher proportion of L-endoglin cells in S and G2-M phases of the cell cycle.
