How is podocyte density measured?

Podocyte density = podocyte number per glomerulus / glomerular volume. Measured on PAS-stained biopsy sections using stereological methods. Podocyte density <200/mm2 is associated with proteinuria and FSGS risk.

What conditions cause podocyte loss?

Podocyte depletion occurs in FSGS, diabetic nephropathy, hypertensive nephrosclerosis, lupus nephritis, and aging. Once lost, podocytes have limited regenerative capacity.

Is podocyte density a therapeutic target?

Podocyte protection strategies include RAAS blockade, vitamin D (anti-proteinuric effect), and SGLT2 inhibitors (reduce hyperfiltration). Direct podocyte-protective drugs are under investigation.

Podocyte Density Loss Estimate from Biopsy

Estimate podocyte depletion from renal biopsy morphometry using podocyte number per glomerulus and podocyte density, which predicts FSGS development and CKD progression.
