11 老鼠肝臟細(xì)胞
這張顯微圖片顯示的是老鼠肝臟的內(nèi)部結(jié)構(gòu)，有助于理解該復(fù)雜器官。呈正弦曲線的血管是圖中遍及肝臟內(nèi)部的粉紅色結(jié)構(gòu)，血管中包含著血紅細(xì)胞和庫(kù)普弗細(xì)胞，它們是肝臟內(nèi)部的巨噬細(xì)胞。肝細(xì)胞是圖中褐色部分，圍繞著正弦曲線血管排列著。
膽汁被分泌進(jìn)小管之中，圖中以綠色管道顯示，它們是肝細(xì)胞之間擴(kuò)大的細(xì)胞間隙，膽汁在其中流向小腸。
This image shows the internal structure of a mouse liver, helping to understand this complex organ. Sinusoids – blood vessels – can be seen as pink structures running through the tissue. These contain red blood cells and Kupffer cells, which are specialist macrophages of the liver. Liver cells, or hepatocytes, shown in brown, are arranged in plates surrounding the sinusoids. Bile is secreted into the passages known as canaliculi, shown as green channels. They are dilated intercellular spaces between hepatocytes, and bile flows through them en route to the small intestine. (Image: Jackie Lewin) [NewScientist]
