Gene Therapeutic Drug pCMV-VEGF165 Plasmid ('Neovasculgen') Promotes Gingiva Soft Tissue Augmentation in Rabbits.

Currently, an increasing number of patients are undergoing extensive surgeries to restore the mucosa of the gums in the area of recessions. The use of a connective tissue graft from the palate is the gold standard of such surgical treatment, but complications, especially in cases of extensive defects, have led to the development of approaches using xenogeneic collagen matrices and methods to stimulate their regenerative and vasculogenic potential. This study investigated the potential of a xenogeneic scaffold derived from porcine skin Mucoderm and injections of the pCMV-VEGF165 plasmid ('Neovasculgen') to enhance soft gingival tissue volume and vascularization in an experimental model in rabbits.

Modulation of the skin and gut microbiome by psoriasis treatment: a comprehensive systematic review.

The microbiome is intricately linked to the development of psoriasis, serving as both a potential cause and consequence of the psoriatic process. In recent years, there has been growing interest among psoriasis researchers in exploring how psoriasis treatments affect the skin and gut microbiome. However, a comprehensive evaluation of the impact of modern treatment approaches on the microbiome has yet to be conducted.

Laser Bioprinting with Cell Spheroids: Accurate and Gentle.

Laser printing with cell spheroids can become a promising approach in tissue engineering and regenerative medicine. However, the use of standard laser bioprinters for this purpose is not optimal as they are optimized for transferring smaller objects, such as cells and microorganisms. The use of standard laser systems and protocols for the transfer of cell spheroids leads either to their destruction or to a significant deterioration in the quality of bioprinting.

Building a tissue: Mesenchymal and epithelial cell spheroids mechanical properties at micro- and nanoscale.

Cell transitions between the epithelial and mesenchymal phenotypes provide the regulated morphogenesis and regeneration throughout the ontogenesis. The tissue mechanics and mechanotransduction play an essential role in these processes. Cell spheroids reproduce the cell density of native tissues and represent simple building blocks for the tissue engineering purposes.
