Forbes和Spereiakis 1979年在小白鼠心室肌层内看到了不寻常的成纤维细胞。其细胞突在某些部位是特别扁的,并含有线条状排列的电子不透明的结构(中央层板“central lamina”)。这些成纤维细胞突起的灶性层板状节段的形态学提示出细胞内的层板是从上下 Forbes and Spereiakis saw unusual fibroblasts in the ventricular myocytes of mice in 1979. The cell processes are particularly flat in some areas and contain linear, electron-opaque structures (central lamina). Morphology of these focal lamina-like segments of these fibroblasts suggests that intracellular laminae are formed from top to bottom
