The figures show normal
kidney histology with most commonly used stains in
nephrology. Figure A shows a normal glomerulus using H&E
stain. The glomerular capillary loops contain RBCs and
are delicate and thin.
The tuft of capillaries lie within the
Bowman's space. Mesangium (the area outside the
glomerular capillaries and surrounded by the glomerular
capillaries) is of normal cellularity. In Figure B, PAS
stain accentuates basement membrane of the glomerular
capillaries, tubular epithelium and also bowman's
capsule. Figures C and D use trichrome stain to
differentiate areas of smooth muscles from areas where
where collagen is present and is widely used in renal
diseases to show areas of fibrosis. Jones stain is used
widely in nephrology to delineate basement membrane. |
