Special Issue Information

Dear Colleagues,

Interdisciplinary advancements in tissue engineering and biomedical engineering have integrated various approaches to reconstruct damaged tissues caused by trauma, disease, or genetic disorders. In addition to the conventional regenerative medicine technologies involved in stem cell transplantation, nanotechnologies and 3D cell culture platforms have exhibited their potential to enhance the therapeutic functions of target cells and tissues. These strategies offer the advantage of making biomimetic adjustments to the complex cellular microenvironment to closely resemble that of healthy tissue. The incorporation of such biological, chemical, physical, and mechanical cues enhances the regenerative efficacy by addressing the shortcomings of conventional cell therapies, such as low engraftment and survival rates.

This Special Issue covers the diverse biomimetic nanotechnologies and 3D cell culture platforms that can advance regenerative medicine and stem cell therapy. This Special Issue focuses on a variety of bioactive nanomaterials, such as polymeric or inorganic nanoparticles, as well as exosomes and cell-derived nanovesicles which are emerging alternatives to cell therapies. With regard to 3D cell culture platforms, the scope encompasses traditional domains, such as spheroids and hydrogels, as well as organoids for transplantation. I welcome original articles that present innovative regenerative strategies, as well as reviews and perspectives that elucidate the authors’ valuable insights.

Type 1 diabetes mellitus (T1DM) is a chronic condition primarily managed with insulin replacement, leading to significant treatment costs. Complications include vasculopathy, cardiovascular diseases, nephropathy, neuropathy, and reticulopathy. Pancreatic islet transplantation is an option but its success does not depend solely on adequate vascularization. The main limitations to clinical islet transplantation are the scarcity of human pancreas, the need for immunosuppression, and the inadequacy of the islet isolation process. Despite extensive research, T1DM remains a major global health issue. In 2015, diabetes affected approximately 415 million people, with projected expenditures of USD 1.7 trillion by 2030. Pancreas transplantation faces challenges due to limited organ availability and complex vascularization. T1DM is caused by the autoimmune destruction of insulin-producing pancreatic cells. Advances in biomaterials, particularly the extracellular matrix (ECM), show promise in tissue reconstruction and transplantation, offering structural and regulatory functions critical for cell migration, differentiation, and adhesion. Tissue engineering aims to create bioartificial pancreases integrating insulin-producing cells and suitable frameworks. This involves decellularization and recellularization techniques to develop biological scaffolds. The challenges include replicating the pancreas’s intricate architecture and maintaining cell viability and functionality. Emerging technologies, such as 3D printing and advanced biomaterials, have shown potential in constructing bioartificial organs. ECM components, including collagens and glycoproteins, play essential roles in cell adhesion, migration, and differentiation. Clinical applications focus on developing functional scaffolds for transplantation, with ongoing research addressing immunological responses and long-term efficacy. Pancreatic bioengineering represents a promising avenue for T1DM treatment, requiring further research to ensure successful implementation. Full article
