Flow cytometric analysis of the ratio of CD34-high-expressing (CD34^high) cells in HaCaT cells. (a) Representative histogram of flow cytometric analysis for CD34^high cells. Left: HaCaT cells were exposed to vehicle (Veh., same volume of PBS to arsenic solution); right: HaCaT cells were exposed to 50 μM sodium arsenite for 24 h. (b) Quantification of CD34^high population in HaCaT cells exposed to Veh. and arsenic. 1 × 10⁵ cells were counted for each sample. . compared with Veh.
