چکیده
In the past two decades, electrospinning has attracted much attention for application in the field of tissue engineering and regenerative medicine. The main reason is that the architectureof electrospun nanofibers greatly mimics the structure of natural extracellular matrix (ECM) in the body [1]. The majorproblem of these scaffolds is their intrinsically twodimensional (2D) nature which inhibits cellular migration and in-growth. Since three-dimensional (3D) organization of cellsand ECM nanofibrills is the common structure in the most of tissues, this problem is critical and should be addressed tofabricate a real biomimetic electrospun scaffolds for efficient nutrient and waste transport, vascularization and tissue ingrowth [2]. In some reports, increased infiltration of cultured surface has been demonstrated via different modifications of the setup parameters or components [3, 4]. In this study, wehypothesized that loosely packed nanofibers would enable cells to migrate smartly through micro-sized interconnectedpores. Loosely packed nanofibers were achieved through a simple modification of the electrospinning process using an array of focused light bulbsکلیدواژه ها
اطلاعات بیشتر در مورد COI
COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.
کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
