obsolete proximal/distal pattern formation involved in mesonephric nephron development (obsolete GO:0061226)
OBSOLETE. The regionalization process in which specific areas of cell differentiation are determined along a proximal/distal axis of a nephron in the mesonephros. The proximal/distal axis is defined by a line that runs from the glomerulus (proximal end) outward toward the mesonephric duct (distal end).
