撇除皮膚的話，肝臟是我們身體最大的器官。720Please respect copyright.ＰＥＮＡＮＡE6utlrmsFJ
除再生能力強大之外，肝臟的另外一個特點就是會與我們的體型成正比關係。720Please respect copyright.ＰＥＮＡＮＡpqZI7ullYa

（圖2）肝臟細胞根據其所在位置，共可分為三個區域(Zone)。720Please respect copyright.ＰＥＮＡＮＡY9j4eYdmUp

三個區域的肝臟細胞在新陳代謝及基因表達上均有顯著的分別。720Please respect copyright.ＰＥＮＡＮＡhuD8f50ewF
譬如說Zone1細胞所獲得的氧氣量比Zone3的為高，Zone1細胞製糖的能力比Zone3的為強。720Please respect copyright.ＰＥＮＡＮＡbDu3sIfNqU
720Please respect copyright.ＰＥＮＡＮＡvcuvpEHBjV
（圖3）在正常情況下，Zone1的肝臟細胞會一直在減少，並由Zone2的細胞繁殖補回所失去的數量，而Zone3的細胞數量則相對上不會有太大變化。720Please respect copyright.ＰＥＮＡＮＡW5KTp1imdw

（圖4）當Zone3區域細胞受損的話，Zone1及2區域細胞便會一起繁殖，填補所失去的細胞。720Please respect copyright.ＰＥＮＡＮＡdbtKYp6HUb
反之，當Zone1區域細胞受損的話，Zone2及3區域細胞便會一起繁殖，對其作出填補。720Please respect copyright.ＰＥＮＡＮＡuSw9Nv02Wv

720Please respect copyright.ＰＥＮＡＮＡlRCPZ8MrVg
若果Zone1、2、3細胞一起受損的話，根據老鼠實驗指出(Ref2)，開頭時份將會由Zone1的細胞主導繁殖，數量到達一定程度後，Zone2區域的細胞便會出手幫忙，而Zone3區域細胞在整個回復的過程中所參與的比例則全程偏低。720Please respect copyright.ＰＥＮＡＮＡIv8yyaqioc

同時亦可以在Penana網站裡按「買一嚿/半嚿薯仔」，以課金的方式推動我繼續搜羅資料寫文，多謝。720Please respect copyright.ＰＥＮＡＮＡ11Lkkn49ls
