FN protein expression in DRG neurons. Dissociated DRG neurons were immunostained for fibronectin (green), neuron-specific βIII tubulin (red) and IB4 lectin labeling (blue) at t=0 (A-D) and t=24 hr after plating on LN (E-H). Both populations of cells express FN with no obvious difference detected by densitometry at t=0, although after 24 hr on LN, an increase in expression was observed for both populations. Scale bar-30 μm.
