Table 1 Terms and abbreviations are allocated to the structural conditions of the outer cortex in the fetal human kidney during late gestation as it was previously published [10, 11]. The thick black lines depict the border of a nephrogenic compartment. The separation between the district of progenitor cell recruitment and the area of nephron shaping is indicated by a transverse double line. The dotted line marks the border between the external nephrogenic zone and the subjacent maturation and matured zones
