Fig. 7. XNBC1 expression in the developing kidney. XNBC1 is expressed in multiple pronephric regions. Expression in the early and late proximal domains begins at stage 29. At stage 33, a new domain of expression is activated in the late distal segment. Once active, this segment expresses much higher levels of XNBC1 than do the proximal tubules. Proximal expression declines over time and is barely detectable by stage 40, at which time late distal expression remains robust. Red arrow, proximal tubule expression. Blue arrow, late distal segment expression. Black arrow, pink coloration in proximal tubules representing low-level expression.
