Effects of ZnCl₂ concentrations on the growth of the 5.1 µm cells in the rat bone marrow cell culture. Rat bone marrow cells were suspension-cultured with 0.01 mM ZnCl₂ (control) to 0.9 mM ZnCl₂ in the presence of medium and 10% rat serum. After 24 h, the harvested cells were measured with a cell counter. Cell growth is expressed as the ratio of the number of 5.1-μm cells at the start of the culture compared with that of the control. The results are the mean ± SD from six independent experiments. *, significant difference between the ZnCl₂ supplemented and control (p < 0.05, n = 6).
