Chondroitin sulfate (marked in red), virtually absent in healthy human heart tissue (upper panel), is found to accumulate in hearts of patients with heart failure, forming dense 'molecular nets' around the heart muscle cells (lower panel). Cell nuclei are marked in blue; scale bar represents 50 μm.
