Effect of Tpo on megakaryocytic differentiation. (A) UT-7 cells were cultured with either Tpo alone or the combination of nocodazole and Tpo as follows. [1] The cells were cultured for 2 days in the presence of 0.1% DMSO, which was used as a solvent for nocodazole. The medium was then replaced with those containing Tpo at the concentration of 10 ng/mL, and the culture was continued for an additional 5 days. [2] The cells were treated with Tpo for 2 days, and the medium was replaced with those containing 0.1% DMSO. The culture was continued for additional 5 days. [3] The cells were treated with 50 ng/mL of nocodazole for 2 days, and the medium was replaced with those containing Tpo. The culture was continued for an additional 5 days. (B) Wright-Giemsa staining of UT-7 cells was performed after the culture with three different conditions as shown above. (Original magnification × 400). (C) The intracellular concentration of β-TG was determined by ELISA after the culture in each condition. The mean ± SD (bar) of three independent experiments is shown.
