CellCyclesIntroduction
The onion root tip and the whitefish blastula remain as the standard introduction to the study of mitosis. The onion has easily observable chromosomes, and the whitefish has one of the clearest views of the spindle apparatus. The testis of the grasshopper and the developing zygote of the roundworm Ascaris are the traditional materials used for viewing the various stages of meiosis.In a single longitudinal section of ......閱讀全文

Cell－Stem－Cell：揭示細胞炎癥記憶機制
當組織經歷炎癥時，它的細胞會記得。在炎癥的高峰期，細胞將蛋白質固定在其遺傳物質上，并將它們在最后斗爭中所處的位置記下來。下次接觸時，炎癥記憶就會啟動。這些細胞利用以前的經驗來更有效地做出反應，即使是對它們以前從未遇到過的威脅也是如此。如果皮膚以前接觸過刺激物，如毒素或病原體，它就會更快地愈合傷口
