machine 39 spherical grinding beirut

May 19, 2015 Counting stellate and spherical colonies on day 3 in 3D cultures showed that K100 increased the percentage of spherical colonies as compared to untreated cells in a dose-dependent manner. At 10 μ M, the number of spherical colonies increased to more than 70% and at 40 μ M up to 97% compared to less than 35% in control untreated cells.
