Hypothesis

The study investigates the mechanism by which activin B induces epithelial wound healing in mice.

Conclusion

Activin B promotes epithelial wound closure in vivo through the RhoA-Rock-JNK-cJun signaling pathway.

Supporting Evidence

  • Activin B significantly increased the number of keratinocytes at the wound edge.
  • RhoA activation enhanced JNK activity, which is crucial for wound healing.
  • JNK inhibition suppressed the wound healing process induced by activin B.

Takeaway

Activin B helps heal wounds by making skin cells grow and move to cover the injury.

Methodology

The study used recombinant lentiviral plasmids to infect wounded mice and monitored the wound healing process with various assays.

Participant Demographics

Male and female specific pathogen-free Kunming (KM) mice aged 10-12 weeks.
