Concanavalin A increases the strength of baby hamster kidney cell attachment to substratum.
The strength of attachment of normal and transformed baby hamster kidney cells was markedly increased when attached cells were treated with concanavalin A (Con A). The cells became less sensitive to detachment by physical shear or by treatment with trypsin or EDTA; however, their morphology, as observed by phase contrast microscopy, did not change. The effects of Con A were prevented by the simultaneous addition of either D-glucose or alpha-methyl-D-glucoside with the Con A. Also addition of these reagents to the attached cells after Con A treatment partially reversed the effects caused by Con A. Pre-treatment of the culture flasks with Con A before cell attachment resulted in an increase in the strength of cell attachment to the culture flasks as compared to untreated controls.
