Grafts of primitive streak and tail bud regions to the kidney capsule. (A) Masson’s trichrome-stained tumour sections derived from the indicated embryonic tissue regions. (B) Percentage of tumours that contain any of the scored tissues. (C) Average tumour area per stage. E7.5 cells give rise to larger tumours compared to tumours, derived from E8.5 or E10.5 grafts (*, p<0.01). a, adipose; b, bone; c, cartilage; ec, embryonal carcinoma cells; kw, keratin whorl; k, adult kidney; n, neural; m, skeletal muscle.
