Josiah Johnston, Cathy Wolkow (2011) CIL:2138, 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C. elegans端部膨大老化旨在基于咽端膨大（摄食器官的一部分）的图像，推导出线虫的年龄。C. elegans的图像在不同生理年龄下采集。该图像属于第4天数据集的一部分。值得注意的是，尽管个体在遗传上相同，但由于个体间的变异，形态学和生理学年龄并不完全相关。数据集的来源为遗传学实验室/国家老年研究所/美国国立卫生研究院。
