CS and neoplasm: According to the obtained data, heparan sulfates (HS) and chondroitin sulfates (CS) expressions and localisation in normal and cancer prostate tissues were tightly associated with the localisation of corresponding core proteins—HS expression was shifted from the normal prostate epithelial cells to tumour stroma, whereas the CS expression was very similar both in normal and tumour prostate tissues with mainly stromal localisation.
