도 5는 억제 ROCK1은 켈로이드 섬유아세포에서 피부 섬유화 및 세포 이동을 약화시키는 것을 나타낸 것이다. A는 pro-fibrotic gene, COL1A1, COL3A1, FN, a-SMA, CTGF 및 PCNA의 mRNA 수준을 qRT-PCR로 분석 결과이다. Y-27632(B) 또는 siROCK1(E)에 의해 억제된 기계 활성화 켈로이드 섬유아세포의 이동 활동이다. Y-27632(C) 및 siROCK1(F)을 사용한 켈로이드 섬유아세포의 억제된 이동 활동의 정량화이다. 축척 막대 = 200μm. 결과는 SD(n=5)의 평균으로 표현되었다. 스튜던트 t 테스트는 모든 분석에 사용된다. *P < 0.05.
