Cell Movement During Development cell mov’t - changing patterns of cell adhesion cadherins - used in cell-to-cell interactions o transmembrane proteins that mediate Ca++ binding o cells w/ similar cadherins tend to go together o cells w/ most cadherins in interior, cells w/ least cadherins on outside integrins - used in cell-to-substrate interactions (involving interactions w/ extracellular matrix) o used when most of tissue made up of spaces between cells (ECM) o connects cytoskeleton to the ECM o can change cytoskeleton growth, way cell secretes materials induction - cell changes due to interactions w/ another cell mosaic development - in Drosophila , where determinants (developmental signals) guide cells on different development paths regulative development - in mammals where cell-cell interactions determine development proteins used as intercellular signals organizers - groups of cells that produce signals for position to other cells o tells other cells of distance to organizer
