Figure 1. Decellularization of the rat kidney.

A&B, Gross appearance of a kidney undergoing decellularization at the beginning A. and end B. of the decellularization process. Hematoxylin and eosin staining of sections of renal cortex before C. and after D. SDS decellularization shows the absence of any cellular content and the integrity of the architecture of glomerular and tubular structures within the scaffold. Transmission electron microscopy images of decellularized kidney demonstrating the absence of cellular components and the preservation of basement membranes integrity. E. normal kidney; F. decellularized kidney scaffold.
