Peroxisomes of the nematode Caenorhabditis elegans: distribution and morphological characteristics.

We analyzed the distribution and morphological characteristics of peroxisomes in the nematode Caenorhabditis elegans by routine electron microscopy, immunoelectron microscopy, and morphometry. Peroxisomes were mainly contained in the epithelial cells of the digestive tract and pharyngeal gland, but some were observed in other cells. Their shape varied from round to twisted.
