Plants have been used for medicinal purposes for thousands of years but they are still finding new uses in modern times. For example, Elaeagnus angustifolia (EA) is a medicinal herb with antinociceptive, anti-inflammatory, antibacterial and antioxidant properties and it is widely used in the treatment of rheumatoid arthritis and osteoarthritis. EA extract was loaded onto poly(ϵ-caprolactone)-poly(ethylene glycol)-poly(ϵ-caprolactone) (PCL-PEG-PCL/EA) nanofibers and their potential applications for bone tissue engineering were studied. The morphology and chemical properties of the fibers were evaluated using Fourier transform infrared spectroscopy, field emission scanning electron microscopy, contact angle measurements and mechanical tests. All the samples had bead-free morphologies with average diameters ranging from 100 to 200 nm. The response of human cells to the PCL-PEG-PCL/EA nanofibers was evaluated using human dental pulp stem cells (hDPSCs). The hDPSCs had better adhesion and proliferation capacity on the EA loaded nanofibers than on the pristine PCL-PEG-PCL nanofibers. An alizarin red S assay and the alkaline phosphatase activity confirmed that the nanofibrous scaffolds induced osteoblastic performance in the hDPSCs. The quantitative real time polymerase chain reaction results confirmed that the EA loaded nanofibrous scaffolds had significantly upregulated gene expression correlating to osteogenic differentiation. These results suggest that PCL-PEG-PCL/EA nanofibers might have potential applications for bone tissue engineering.

Tissue engineering (TE) is an integrated discipline that involves engineering and natural science in the development of biological materials to replace, repair, and improve the function of diseased or missing tissues. Traditional medical and surgical treatments have been reported to have side effects on patients caused by organ necrosis and tissue loss. However, engineered tissues and organs provide a new way to cure specific diseases. Scaffold fabrication is an important step in the TE process. This paper summarizes and reviews the widely used scaffold fabrication methods, including conventional methods, electrospinning, three-dimensional printing, and a combination of molding techniques. Furthermore, the differences among the properties of tissues, such as pore size and distribution, porosity, structure, and mechanical properties, are elucidated and critically reviewed. Some studies that combine two or more methods are also reviewed. Finally, this paper provides some guidance and suggestions for the future of scaffold fabrication.

聚合物分子链取向度是决定纤维机械性质和物理性能的关键结构参数。然而,理解和大幅调控纤维大分子链取向仍面临巨大挑战。本文提出一种新型的静电纺丝方法,通过控制纺丝过程中的电场来有效调节分子链取向。与典型的静电纺丝相比,新型静电纺丝通过将电场施加在圆环上而非针头上来分离控制电场。得益于这一变化,实现了一种新的电场分布,从而产生非单调变化的牵伸作用力。结果表明,聚环氧乙烷(PEO)纳米纤维的大分子链取向得到显著改善,实现了超高红外二向色性比。与此同时,PEO射流细度可有效降低80%左右,纳米纤维直径从约298 nm降低至约114 nm。并且,与普通材料中高取向导致的高结晶度不同,该方法在提高纤维分子链取向度的同时使结晶度从74.9%显著降低至31.7%。这项工作为制备具有优化取向-结晶度特性的先进电纺纳米纤维提供了新的认识。
