Developmentally regulated slime mold lectins and specific cell cohesion.


Evidence has been presented that cell surface lectins and complementary receptors appear on the surface of slime molds cells of 2 species, D. discoideum and P. pallidum, as they differentiate from a noncohesive to a cohesive form. Cohesion of P. pallidum cells measured to a quantitative assay can be blocked by reagents that would be expected to interfere… (More)
