Figure 2

Photographs of the wound healing process in different groups: Lactobacillus fermentum supernatant-loaded chitosan nanogel as group 1, Lactobacillus reuteri supernatant-loaded chitosan nanogel as group 2, Bacillus subtilis sp. natto supernatant-loaded chitosan nanogel as group 3, chitosan nanogel without probiotic lysate as group 4, and the control group which receives no treatment as group 5. The photographs were taken after day 2, day 6, and day 14.
