Description
Abstract
Carbohydrates have been implicated in cell adhesion and in developmental processes. Lectin histochemistry using ConcanavalinA and Lotus lectin was used to localize lectin-accessible mannosyl and fucosyl residues in a maturing sponge developing from histoblasts generated during germination of a gemmule. With the exception of cystencytes found in the sponges stained with Lotus lectin, a similar staining pattern was seen with the two lectins, but there was a rather significant difference in the intensity of staining. This difference in staining intensity was thought to be a result of either more mannosyl residues available to the lectin or that the concentration of mannosyl residues in Ephydatia mulleri is greater than the concentration of fucosyl residues.
