采用分期扫描细胞光度法对年轻成年大鼠小脑feulgen染色细胞核进行了研究。大多数浦肯野细胞的吸光度值呈高斯分布，方差系数较低。该群体的吸光度峰值与颗粒细胞相同。大约1%的浦肯野细胞的染色含量表明DNA含量为4C。对于颗粒状和浦肯野细胞群，极少数细胞核具有介于2C-4C之间的吸光度值。普遍的浦肯野细胞二倍体是支持的。不建议该种群为四倍体和/或超二倍体。
Feulgen-stained cell nuclei of the cerebellum of young adult rats were studied by stage scanning cytophotometry. The absorbance values of the majority of the Purkinje cells showed a Gaussian distribution with a low coefficient of variance. The peak absorbance of this population was the same as the granule cells. About 1% of the Purkinje cells measured had a stain content indicating a 4C amount of DNA. For the granular and Purkinje cell population a very small number of nuclei possesses absorbance values intermediate from 2C-4C. Prevalent diploidy of the Purkinje cells is supported. A tetraploid and/or hyperdiploid status of this population is not suggested.
