A review of: Application of synthetic scaffold in tissue engineering heart valves

Characterization of maghemite (γ-Fe2O3)-loaded poly-l-lactic acid/thermoplastic polyurethane electrospun mats for soft tissue engineering

“…The tests were done at room temperature (25°C) with a cross-head speed of 10 mm/min. According to the literature, the required tensile strength values for the human tissue such as heart valve, blood vessel, bone cartilage, tendons, and others are within the range of 8-160 MPa [8,31]. The elastic modulus was calculated through Eq.…”

“…The requirement of anticoagulation treatment and the durability of artificial prostheses as well as non-viable structure and no capacity to remodel, repair, or grow are the other drawbacks [5][6][7]. Almost 50-60 % of patients will experience a problem with artificial organs and correspondingly would go for reoperation [8]. These drawbacks particularly in newborn babies' cases made the scientist to think about a new concept called tissue engineering.…”

“…TE opens a new insight into biomedical engineering to overcome the limitation of artificial biomedical devices [9][10][11]. The concept of tissue can be shortened in three major parts: (I) the 3D biomaterial scaffold fabrication, (II) the cell source and cell cultivation over the scaffold, and (III) the development conditions of the scaffold prior to implantation [8]. Although effective steps have been made toward developing tissue constructs that could assist as origin parts of the clinical devices, the functional properties of many of these engineered tissues fail to fully match compared to their native counterparts.…”

Caracterización de compositos biocerámicos en esponjas de titanio mediante interpenetración por corriente pulsada asistida

“…Actualmente, se están llevando a cabo una gran cantidad de estudios sobre el desarrollo tecnológico de los procesos de manufactura para soportes (andamios) de ingeniería de tejidos humanos [1]. La impresión 3D aplicada a la ingeniería de tejidos requiere del desarrollo de técnicas computacionales como el modelado estereolitográfico y de procesos de manufactura especiales como son el sinterizado por láser o la deposición por extrusión, por mencionar sólo algunos [2].…”

“…Recently, it has been directing some special attention to the development of new manufacturing processes, with engineering applications in human tissues [1]. 3D printing applied to tissue engineering requires pulse computational techniques such as stereolithographic modeling, and special manufacturing processes, to name a few; Laser Sintering or Extrusion Deposition [2].…”
