Dermal GAGs in kidney patients (recipients) and healthy individuals (donors). Immunohistochemical expression and quantification of GAGs and versican and mRNA expression of enzymes involved in the synthesis of HS-GAG (a, b), CS/DS-GAG (c, d) and HA-GAG (e, f). Photos: magnification ×200. For qRT-PCR data, values are expressed in fold increase compared to the mean of the donors. Mann–Whitney and Kruskall Wallis were used to test differences between two or more groups. *p < 0.05
