Tissue engineering has evolved as a dynamic research field that encompasses multidisciplinary approaches involving cytology,material science,bioreactor engineering,and medicine.The overarching goal is to construct human tissue and organs in the laboratory for tissue regeneration or replacement.It offers a potential solution to the donor shortage in organ transplantation and to the difficulties in regenerative medicine.The basic components for tissue engineering include seed cell selection,bio-scaffold construction,and ex vivo tissue formation via a bioreactor. Over the past decade,tremendous progress has been made in bioengineering cartilage,trachea,urinary bladder,heart valve and endocrine tissues. However,there remain significant challenges in creating complex and human-sized tissues and organs for clinical use.In this article,we review the basic components and strategies for bioengineering organs. We attempt to provide an overview of current progress and challenges in developing organ-level tissue engineering and in the successful translation of bioengineered tissue and organ products into daily clinical practice.

Objective:To study the effects of vitamin C (VC) on the injury of alveolar macrophages exposed to Ni2O3 in vitro and the expression of inducible nitric oxide synthase (iNOS). Method:The alveolar macrophages were cultured with exposure to Ni2O3 in vitro. Meanwhile,VC with different concentrations (25,50 and 100 ?mol/L) were added to the medium, respectively. The cell activity,nitric oxide(NO),reactive oxygen species (ROS), malondialdehyde (MDA) and activities of SOD, GSH-Px,CAT and iNOS were detected. iNOS mRNA expression was detected by using RT-PCR. Results:VC could decrease mortality and increase survival activity of alveolar macrophages. VC could also decrease ROS,NO and NOS activity,increase SOD,GSH-Px, CAT activities and downregulate the expression of iNOS mRNA. Conclusion:The lipid peroxidation of alveolar macrophage could be induced by Ni2O3. VC could downregulate the expression of iNOS mRNA and reduce the production of ROS and NO through increasing the activity of antioxidative enzymes and antagonize the oxidative damage induced by Ni2O3.
