请将下方内容用更为地道、更为科学的英文表达出来：When the fibrin proportion reached 50 and above the vessel positive area did not continue to extend Figure 1C When the fibrin proportion reached 70 and above the epithelial org

Upon reaching a fibrin proportion of 50% and higher, there was no further extension of the vessel positive area observed (Figure 1C). Notably, at a fibrin proportion of 70% and higher, the epithelial organoids displayed a significant level of adhesion to the culture dish, in contrast to a minimal level of adhesion observed when the fibrin proportion was below 50%.
