it is suggested that in vivo the cell adhesion factor is stored in the secretory granules of the semigranular and the granular cells in a putative inactive pro-form , which can be released during exocytosis and , in the presence of beta-1,3-glucans or lps , be activated outside the cells to mediate cell attachment and spreading , processes of essential importance in arthropod host defense .
