The purpose of the dataset C. elegans muscle aging is to deduce the age of the nemathode based on images of muscles. Images of C. elegans were taken at different chronological ages. This image is part of the day 8 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.
C. elegans muscle age is a data set of fluorescence 20X microscopy images of C. elegans nematodes stained with phalloidin to visualize actin in muscles at different ages (1,2,4, and 8). Note that the data sets for each age can be found by searching for a featured image from each set: CIL 1005, 1057, 1105, and 1265, respectively.
