<p>Mice were sacrificed 2 months after co-transplantation surgery, and the kidneys from the cell implanted nude mice were collected. (A) Graft initiated with hUC-MSCs alone and (B) rUGSSs alone were used as negative control, respectively. (C) Graft derived with hUC-MSCs and rUGSSs. (D–F) Histological analyses of the sections of the graft stained for haematoxylin and eosin (H&E). (D) Note that while hUC-MSCs alone and (E) rUGSSs single cell type transplantation fail to regenerate prostate glandular structures. (F) co-transplantation of hUC-MSCs and rUGSSs gives rise to prostate glandular structures. Scale bar 50 µm.</p
