metanephric mass of intermediate mesoderm, metanephric cap.

met·a·neph·ric mass of mes·o·derm

(met'a-nĕf'rik mas mez'ŏ-dĕrm)
The mesoderm covering the distal end of the metanephric diverticulum; it gives rise to the nephrons in the permanent kidneys.

The development of the mammalian kidney is guided by reciprocal inductive interactions between the ureteric bud (UB, giving rise to the collecting duct system) and the metanephric mesenchyme (giving rise to all other renal epithelial cells) [13].
Upregulation of Wnt4, which mediates epithelialization of the metanephric mesenchyme, has been detected after exposure of mesenchymal stem cells to hypoxia [16].

Serotype 2 preferred to infect the ureteric bud (UB) cells compared with metanephric mesenchyme (MM) cells, while serotype 8 showed ubiquitous infection ability to UB and MM cells (around the UB tips) (Figure 3).
E-cadherin-null mice show decreased nephrons due to a failure of proper fusion of metanephric mesenchyme to the ureteric bud (Mah et al.
PAX2 is one of 9 paired-box transcription factors, a master organizer gene expressed in the nephric duct, metanephric mesenchyme, ureteric bud, and S-shaped body.
Wilms tumor occurring in the kidney is thought to arise from aberrant differentiation of persistent metanephric mesenchyme.[9] Although the exact histogenesis of EWT is unclear, origin from persistent embryonic nests of primitive renal anlage is favored.
