![]() The use of autologous whole blood ensures compatibility and promotes effective wound healing. In contrast to previous methods reliant on cell-laden hydrogel patches using fat tissues or platelet-rich plasma, this innovative approach enables the creation of robust microcapillary vessel networks within skin wounds. These implants hold immense promise for diverse applications requiring vascular regeneration, including the treatment of chronic wounds.Ī group of researchers associated with UNIST (Ulsan, Korea) has devised a microfluidic system capable of transforming blood into an artificial tissue scaffold. A research team has achieved a significant breakthrough in tissue regeneration by developing technology that harnesses autologous blood to create three-dimensional microvascular implants. In severe cases, they can culminate in sepsis, a life-threatening condition, due to inadequate oxygen and nutrient supply resulting from the loss of blood vessels. Oxygen levels were measured in 3-D constructs comprising the artificial cancer mass using the OxyLite tissue oxygenation monitoring system.Chronic wounds present formidable challenges, often defying proper healing and leading to complications associated with conditions like diabetes and vascular diseases. Used the OxyLite sensors to take pO 2 readings across the tissue cultivation platform within a closed bioreactor.Ī Novel Tissue Engineered Three-Dimensional in vitro Colorectal Cancer Model Oxygen tension in the hydrogels with or without MSC encapsulation was measured using an OxyLite fibre-optic oxygen micro-sensor.ĭeveloping a Customized Perfusion Bioreactor Prototype with Controlled Positional Variability in Oxygen Partial Pressure for Bone and Cartilage Tissue Engineering High Oxygen Preservation Hydrogels to Augment Cell Survival under Hypoxic Conditions Then used the OxyLite monitor to measure the collagen models pO 2 levels in real time. Used to HypoxyLab to set O 2 levels of the 3D to cell collagen-based models. ![]() Rapid Evaluation of Novel Therapeutic Strategies Using a 3D Collagen-Based Tissue-Like Model In vitro scaffold research and Oxford Optronixīelow are some recent publications in this area. The image is a summary of the 3 primary tissue engineering areas, namely engineering cells (stem cells and genetic tools), engineering materials (growth factors, chemistries, and biomechanics), and the available tissue architectures (self-assemblies, 3D printing, and decellularized scaffolds). ![]() From “A decade of progress in tissue engineering” by Khademhosseini & Langer (2016) As researchers continue to need to control and identify oxygen levels within scaffolds, Oxford Optronix is in a unique position to help these researchers on both ends of this spectrum. It has been shown that the change in oxygen concentration in an artificial or tissue-engineered graft affects cell survival, differentiation, and tissue growth in profound ways. As oxygen is one of the most important molecules for sustaining life, it is understood that it is also an important variable to consider in tissue engineering and regenerative medicine. As such, these biomaterials are most often developed in vitro first and then fully fleshed out within animal models.Īs biocompatibility is important, researchers do attempt to make their cellular models and scaffolds work as close to what would be seen in the in vivo condition. In its most general sense, biocompatibility may be characterized as the ability of a biomaterial to perform its desired function with respect to a medical therapy, without eliciting any undesirable local or systemic effects in the recipient or beneficiary of the therapy. A fundamental property of scaffolds is their biocompatibility. Scaffolds are support structures used in tissue engineering that are designed to assist cellular growth and proliferation of certain cells upon implantation onto a specific tissue.
