CIL:1948, Caenorhabditis elegans. In Cell Image Library

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**秀丽隐杆线虫咽端球衰老（C. elegans terminal bulb aging）**的构建目标为：基于秀丽隐杆线虫（C. elegans）咽端球——其进食器官的组成部分——的显微图像，推断该线虫的实龄。研究人员采集了不同实龄阶段的秀丽隐杆线虫图像，本次提供的图像属于第4天数据集的一部分。需注意，即便个体遗传背景完全一致，线虫个体间仍存在差异，因此形态年龄与实龄之间并非完全相关。本数据集的来源为美国国立卫生研究院（NIH）下属国家衰老研究所（NIA）遗传学实验室。
