Abstract
The paper highlights how significant characteristics of liver can be modeled in tissue-engineered constructs using unconventional scaffolds. Hepatic lobular organization and metabolic zonation can be mimicked with decellularized plant structures with vasculature resembling a native-hepatic lobule vascular arrangement or silk blend scaffolds meticulously designed for guided cellular arrangement as hepatic patches or metabolic activities. The functionality of hepatocytes can be enhanced and maintained for long periods in naturally fibrous structures paving way for bioartificial liver development. The phase I enzymatic activity in hepatic models can be raised exploiting the microfibrillar structure of paper to allow cellular stacking creating hypoxic conditions to induce in vivo-like xenobiotic metabolism. Lastly, the paper introduces amalgamation of carbon-based nanomaterials into existing scaffolds in liver tissue engineering.
论文重点介绍了如何利用非常规支架在组织工程构建物中模拟肝脏的重要特征。肝小叶组织和新陈代谢分区可通过脱细胞植物结构进行模拟,该结构的脉管与原生肝小叶血管排列相似,或通过丝绸混合支架进行精心设计,以引导细胞排列为肝补片或新陈代谢活动。肝细胞的功能可在天然纤维结构中得到增强和长期保持,为生物人工肝的开发铺平了道路。利用纸张的微纤维结构,可以提高肝脏模型的 I 期酶活性,允许细胞堆叠,创造缺氧条件,诱导类似活体的异生物代谢。最后,论文介绍了在肝组织工程中将碳基纳米材料与现有支架的结合。
期刊介绍:
Regenerative medicine replaces or regenerates human cells, tissue or organs, to restore or establish normal function*. Since 2006, Regenerative Medicine has been at the forefront of publishing the very best papers and reviews covering the entire regenerative medicine sector. The journal focusses on the entire spectrum of approaches to regenerative medicine, including small molecule drugs, biologics, biomaterials and tissue engineering, and cell and gene therapies – it’s all about regeneration and not a specific platform technology. The journal’s scope encompasses all aspects of the sector ranging from discovery research, through to clinical development, through to commercialization. Regenerative Medicine uniquely supports this important area of biomedical science and healthcare by providing a peer-reviewed journal totally committed to publishing the very best regenerative medicine research, clinical translation and commercialization.
Regenerative Medicine provides a specialist forum to address the important challenges and advances in regenerative medicine, delivering this essential information in concise, clear and attractive article formats – vital to a rapidly growing, multidisciplinary and increasingly time-constrained community.
Despite substantial developments in our knowledge and understanding of regeneration, the field is still in its infancy. However, progress is accelerating. The next few decades will see the discovery and development of transformative therapies for patients, and in some cases, even cures. Regenerative Medicine will continue to provide a critical overview of these advances as they progress, undergo clinical trials, and eventually become mainstream medicine.
