About this Research Topic
Tissue Engineering is attracting worldwide interest, demonstrating the immeasurable possibilities to successfully overcome the lack of organ donors. Nevertheless, to date most strategies so far lack crucial features for appropriately mimicking native live tissues, guiding the surrounding microenvironment to promote self-healing and towards the development of tailored functionally-graded tissues with reduced toxicity. Tailoring cell-construct interactions and implementing appropriate and finely tuned chemical/molecular signals, contribute to achieve the structural and functional mimicry of the physiological process of tissue formation. Nano-scale features of developed tissues and medical implants may drive dynamic modeling in response to environmental stimuli.
Current improvements in understanding the interactions between implants and human cells have led to the rapid development of novel artificial tissues and bioconductive medical devices. However, the design of a surface that guides its surrounding biology is still a crucial issue in tissue engineering research. New multifunctional nanomaterials can potentially allow the design of tailored implants thanks to their nanoscale features capable of driving cell behavior. These can be also combined with engineered proteins and extracellular vesicles from biological fluids to enhance implant bioconductivity and modulate cell interaction. The goal of this Research Topic is to highlight the potential of nanomaterials design and formulation in driving unique cell response and to highlights possible toxicology mechanisms after in vivo implantation.
To this aim, we will collect research papers and reviews of recent literature focused on new nanomaterials and/or synthesis methods employed for artificial tissues as well as for medical device production. How can the latest development of nanotechnology improve cell interaction with implants’ surface? How soon technologies like bioprinting can be transferable to the clinical setting? How much can we control the long-term toxicity of these new materials inside the body? Can we reduce the immune response by modifying the material through clever design? Can biotechnology and the use of cellular extracts improve outcome in vivo and reduce immunotoxicity? These are some of the questions that will be tackled in this Research Topic.
