Abstract

From three-dimensional diameter measurements of eleven kinds of cells pertaining to five different organs, which were excised from eleven adult mammals (nine species) whose body weight range was 40 g to 450 kg, we calculated the corresponding cell soma areas (A), volumes (V), and finally their area-volume ratios (A/V). The dissimilarities among these eleven cell types could be established quantitatively by means of a cluster analysis. The dendrograms for cell areas (A), volumes (V), and their corresponding area-volume ratios (A/V), yielded similar groupings when cell areas and volumes were compared, yet the grouping of the area-volume ratios (A/V) for the eleven types of cells was different. These results were corroborated by means of the principal components analysis, where five distinct cell groupings could be established. The relationship between cellular morphometry, oxidative metabolism, and body mass, was established by means of the fractal geometry of the transport systems (respiration and circulation), which provides the tools for the scale-dependent analysis of the surfaces across which the transport of metabolites is performed.

哺乳动物细胞的三维形态计量学。2面积,体积和面积体积比。
从体重40 ~ 450 kg的11种成年哺乳动物(9种)中,对5种不同器官的11种细胞进行了三维直径测量,计算出相应的体细胞面积(A)、体积(V)和面积体积比(A/V)。通过聚类分析,可以定量地确定这11种细胞类型之间的差异。当比较细胞面积和体积时,细胞面积(A)、体积(V)及其相应的面积体积比(A/V)的树突图产生了相似的分组,但11种细胞的面积体积比(A/V)的分组不同。这些结果被证实通过主成分分析的手段,其中五个不同的细胞组可以建立。细胞形态测定学、氧化代谢和体重之间的关系是通过运输系统(呼吸和循环)的分形几何来建立的,这为代谢物运输的表面的尺度依赖分析提供了工具。
