Josiah Johnston, Cathy Wolkow (2011) CIL:1922, Caenorhabditis elegans. CIL. Dataset

The purpose of the dataset C. elegans terminal bulb aging is to deduce the age of the nemathode based on images of the pharynx terminal bulb (part of the eating apparatus). Images of C. elegans were taken at different chronological ages. This image is part of the day 4 data set. Note that the morphological and chronological ages are not fully correlated due to the variability among individuals even though the individuals are genetically identical. The source for the dataset is Laboratory of Genetics/NIA/NIH.

本数据集旨在通过分析秀丽隐杆线虫咽部终末泡（摄食器官的一部分）的图像，推断出线虫的年龄。数据集中包含了在不同生理年龄下拍摄的秀丽隐杆线虫图像，其中本图属于第4天的数据集。需要注意的是，尽管个体间基因型相同，但由于个体间的差异性，形态学年龄与生理年龄之间并不完全一致。本数据集的来源为美国国立卫生研究院（NIH）国家老年研究所（NIA）遗传学实验室。
