Recent experimental studies revealed that angiogenesis and lymphangiogenesis are closely related to psoriasis. Our microarray analysis suggested that the pro-angiogenic genes platelet endothelial cell adhesion molecule-1 (PECAM1), facio-genital dysplasia-5 (FGD5), prostaglandin-endoperoxide synthase-1 (PTGS1), melanoma cell adhesion molecule (MCAM), vasohibin-2 (VASH2), and stabilin-1 (STAB1) are differentially expressed in dermal mesenchymal stem cells in psoriasis.


The aim of this study was to investigate the mRNA and protein expression of PECAM1, FGD5, PTGS1, MCAM, VASH2, and STAB1 for angiogenesis and the possible mechanisms in psoriasis.


We studied 12 patients with plaque psoriasis and 14 healthy controls matched for age and sex. Dermal mesenchymal stem cells were expanded, passaged, and identified by cellular morphology, immunophenotyping, and multipotential differentiation. The mRNA and protein expression of the above-mentioned six genes were confirmed by quantitative real-time reverse transcription-polymerase chain reaction and Western blotting.


The significantly decreased expression of PECAM1, PTGS1, FGD5, and MCAM at both mRNA and protein level (except VASH2 and STAB1) were demonstrated in mesenchymal stem cells from psoriatic skin lesions compared with non-lesional from healthy controls.


We provide the first report that pro-angiogenic genes PECAM1, PTGS1, FGD5, and MCAM rather than VASH2 and STAB1 may be play a vital role in pathological dermal angiogenesis disorders of psoriasis. Therefore, anti-angiogenesis is attractive and offers future potential for application in patients with psoriasis.
