The results show that the concentric lamellated structure has genetic characteristics of micromicellae,and that the psammoma bodies are composed of nano-size carbon hydroxyapatite and some amorphous calcium phosphates with relatively low values of Ca/P(At%).
研究结果表明,甲状腺乳头状癌中砂粒体是由纳米尺寸的粒状、短柱状碳羟磷灰石及一些无定形低Ca/P(原子分数,下同)的磷酸钙矿物混合组成,砂粒体的同心层状构造具有微胶粒成因的特征,是结构和成分不同的直接反映,砂粒体中Ca、P及Ca/P的分布具有从外向内逐渐升高的趋势。
