Glycosaminoglycans are polysaccharides of the extracellular matrix supporting
skin wound closure. Mesoglycan is a mixture of glycosaminoglycans such as
chondroitin-, dermatan-, heparan-sulfate and heparin and is the main component of
Prisma(®) Skin, a pharmaceutical device developed by Mediolanum Farmaceutici
S.p.a. Here, we show the in vitro effects of this device in the new vessels
formation by endothelial cells, since angiogenesis represents a key moment in
wound healing. We found a strong increase of migration and invasion rates of
these cells treated with mesoglycan and Prisma(®) Skin which mediate the
activation of the pathway triggered by CD44 receptor. Furthermore, endothelial
cells form longer capillary-like structures with a great number of branches, in
the presence of the same treatments. Thus, the device, thanks to the mesoglycan,
leads the cells to the Endothelial-to-Mesenchymal Transition, suggesting the
switch to a fibroblast-like phenotype, as shown by immunofluorescence assays.
Finally, we found that mesoglycan and Prisma(®) Skin inhibit inflammatory
reactions such as nitric oxide secretion and NF-?B nuclear translocation in
endothelial cells and Tumor Necrosis Factor-? production by macrophages. In
conclusion, based on our data, we suggest that Prisma(®) Skin may be able to
accelerate angiogenesis in skin wound healing, and regulate inflammation avoiding
chronic, thus pathological, responses.
