CIL:1694^*

Description

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 2 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.

Technical Details

Terminal Bulb is a dataset of DIC (differential interference contrast) 20x microscopy images of the pharynx terminal bulb of C. elegans at different ages (0, 2, 4, 6, 8, 10, 12 days). Note that the data sets for each age can be found by searching for a featured image from each set: CIL 1587, 1694, 1905, 2213, 2622, 2544, and 2606, respectively.
