Morphology. H&E stain of control (A, F, K) and decellularized adult rhesus monkey kidney sections. H&E of kidney decellularized with 1% SDS at 4°C (B, G, L) or 37°C (C, H, M), or 1% Triton X-100 at 4°C (D, I, N) or 37°C (E, J, O) for 10 days. Structurally intact glomerular basement membrane remained after decellularization with SDS at 4°C (L). Condensed ECM resulting from treatment with SDS at 37°C (H, M, arrows), and severe disruption of basement membrane from treatment with Triton X-100 (I, N, arrows); note residual cell nuclei (J, O, arrows). H&E, hematoxylin and eosin; ECM, extracellular matrix; g, glomeruli; bc, Bowman's capsule. Color images available online at www.liebertonline.com/ten.
