Isolation of renal fetal and mature extracellular matrix proteins. (A) Workflow for the isolation of the extracellular matrix (ECM) from healthy human fetal and mature renal tissue. (B) Macroscopic appearance of representative human fetal and mature renal samples before and after decellularization (left panels). Scale bar represents 5 mm. Hematoxylin and eosin staining (200× magnification) of human fetal and mature renal tissue before and after decellularization demonstrates the successful removal of cellular components (right panels). Scale bar represents 100 μm.
