text: 'Cells at different positions in a developing tissue receive different concentrations
of signaling molecules, called morphogens, and this influences their cell fate.
Morphogen concentration gradients have been proposed to control patterning as
well as growth in many developing tissues. Some outstanding questions about tissue
patterning by morphogen gradients are the following: What are the mechanisms that
regulate gradient formation and shape? Is the positional information encoded in
the gradient sufficiently precise to determine the positions of target gene domain
boundaries? What are the temporal dynamics of gradients and how do they relate
to patterning and growth? These questions are inherently quantitative in nature
and addressing them requires measuring morphogen concentrations in cells, levels
of downstream signaling activity, and kinetics of morphogen transport. Here we
first present methods for quantifying morphogen gradient shape in which the measurements
can be calibrated to reflect actual morphogen concentrations. We then discuss
using fluorescence recovery after photobleaching to study the kinetics of morphogen
transport at the tissue level. Finally, we present particle tracking as a method
to study morphogen intracellular trafficking.'
