Fig 2. Cryostorage retains the basic kidney micro-architecture and undergoes decellularization to a similar level as in freshly isolated kidneys.

Photomicrographs represented H&E staining of a) control kidneys from group, I b) decellularized structure from freshly isolated kidney, group II, c) decellularized structure from cryostored kidney, group III at 200X. Well preserved ECM architecture with no evidence of residual nuclei or intact cells as resolved by Hematoxylin (blue stained nuclei) and Eosin (pink stained intracellular proteins), could be seen in both the cryostored kidneys (group III and freshly isolated kidneys group II). Black arrow represents renal cells.
