Biological process

proximal-distal pattern formation involved in metanephric nephron development, proximal/distal metanephric nephron patterning

The regionalization process in which specific areas of cell differentiation are determined along a proximal/distal axis of a nephron in the metanephros. The proximal/distal axis is defined by a line that runs from the center of the kidney (proximal end) outward (distal end).
