Immunohistochemical localisation and staining intensity of DLK1 in Wilms tumours
| Tumour group | Tumour no | Epi | Bl | Str |
|---|---|---|---|---|
| Each column shows the range of expression: no detectable expression, –; mild, +; moderate, ++; high expression, +++. | ||||
| Bl, blastemal; Epi, epithelial; ILNRs, intralobar nephrogenic rests; LOH, loss of heterozygosity; LOI, loss of imprinting; Str, stromal. | ||||
| LOI tumours with myogenesis | LOI-15 and LOI-16 | −/+ | −/+ | +/++ (myogenic) |
| LOI tumours without myogenesis | LOI-11 | −/+ | – | +++ (macrophage) |
| WT1 mutant tumours | WT1-1 to WT1-8 | −/+ | −/+ | ++/+++ (myogenic) |
| ILNRs | WT1-1 and WT1-2 | +/++ | −/+ | – |
| LOH tumours | LOH-2 and LOH-3 | −/+ | −/+ | – |
