Effect on the proliferation of HaCaT cells (MTT) in the (A) base preparation and (B) the preparation containing probiotic microspheres. Results were calculated as the percentage of control cells incubated in the presence of DMEM + FBS and presented as mean ± SEM. *—p = 0.05–0.011; ** — p ≤ 0.01; ***—p ≤ 0.001; ****—p ≤ 0.0001. The green bar indicates the unstimulated control.
