Ultrastructural study of 9 cases of cerebellar hemangioblastoma demonstrated the presence of three major component cells: endothelial cells, pericytes, and stromal cells. These three kinds of cells share the following similar fine features: presence of micropinocytic vesicles, lots of microfilaments, hemidesmosomes, and basement membranes. Weibel-palade bodies were found not only in the endothelial and stromal cells but also in the pericytes. We support the idea that these three kinds of cells belong to a common lineage. Ultrastructurally, pericytes show less differentiation than endothelial and stromal cells. Some transitional forms between pericytes and endothelial cells, or between pericytes and stromal cells were obtained. We suggest that pericytes probably have the capacity of being transformed to endothelial and stromal cells.
对9例小脑成血管细胞瘤的超微结构研究表明，存在三种主要成分细胞：内皮内皮内皮成血管细胞、周细胞和基质细胞。这三种细胞具有以下相似的精细特征：存在微饮小泡、大量微丝、半桥粒和基底膜。不仅在内皮细胞和基质细胞中发现了魏-帕小体，在周细胞中也发现了。我们支持这三种细胞属于共同谱系的观点。在超微结构上，周细胞的分化程度低于内皮细胞和基质细胞。获得了周细胞与内皮细胞之间或周细胞与基质细胞之间的一些过渡形式。我们认为周细胞可能具有向内皮细胞和基质细胞转化的能力。
