Fig. 5From: Lactobacillus reuteri extracts promoted wound healing via PI3K/AKT/β-catenin/TGFβ1 pathwayLocal injection of Lactobacillus reuteri extracts promoted wound healing process in mice by histopathological analysis. h&e staining results showed that the length of wound healing in gingiva tissues in the NS group (d, g, j), and the Lactobacillus reuteri extracts group (e, h, k). a–c The original location of the wound healing model. f, i, l Quantitative analysis of the length of the wound. Yellow dotted line: the original length of the wound. Black line: the length of the wound. Scale bar: 50 μm. Error bars represent SD (n = 6). *P ≤ 0.05; **P ≤ 0.01Back to article page
