3D Bioplotter Research Papers

A wound, defined as a disruption in the continuity of the skin, is among the most common issues in the population and poses a significant burden on healthcare systems and economies worldwide. Despite the countless medical devices currently available to promote wound repair and skin regeneration, there is a growing demand for new skin devices that incorporate innovative biomaterials and advanced technologies. Bioglasses are biocompatible and bioactive materials capable of interacting with biological tissues. Due to their ability to promote fibroblast proliferation, angiogenesis, collagen production, and evade antibacterial activity, they have been suggested as key players in the skin regeneration…

Fibrosis is shared in multiple diseases with progressive tissue stiffening, organ failure and limited therapeutic options. This unmet need is also due to the lack of adequate pre-clinical models to mimic fibrosis and to be challenged novel by anti-fibrotic therapeutic venues. Here using bioprinting, we designed a novel 3D model where normal human healthy fibroblasts have been encapsulated in type I collagen. After stimulation by Transforming Growth factor beta (TGFβ), embedded cells differentiated into myofibroblasts and enhanced the contractile activity, as confirmed by the high level of α − smooth muscle actin (αSMA) and F-actin expression. As functional assays, SEM…
