Probiotic-Derived Polyphosphate Accelerates Intestinal Epithelia Wound Healing through Inducing Platelet-Derived Mediators

Figure 5

The supernatant of poly P-treated PRP activated the ERK signaling pathway and increased the wound healing effect in epithelial cells. Western blotting showed that the activation of ERK, p38, Akt, and JNK was induced by treatment with the supernatant of poly P-treated PRP (a). The activation of ERK, p38, Akt, and JNK was inhibited by FR180204, SB203580, LY294002, and SP600125, respectively. The wound healing effects by the supernatant of poly P-treated PRP were significantly decreased by the inhibition of ERK, but not p38, Akt, or JNK signaling (b–e) according to a two-factor ANOVA. Western blotting showed that upstream Raf-MEK-ERK signaling was activated (f). The error bars and numbers show the standard deviation. by Student’s -test (a, f).
