BIOPRINT

At the Annual Meeting of the American Association for the Advancement of Science (Washington/USA), one of the stars is bioprinting. Professor Hod Lipson of Cornell University, showed a video that shows how are bioprinted in 3D, skin and human ears, hoping to build later bones, liver, cartilage, and the entire human body line by line, layer by layer. Another application of bioprinting is food processing and performing biological experiments. The skin produced by bioprinting will help many burned knowing that 30% of war wounds involve the skin. Hod Lipson, has a well-established project (Lab @ Home) in continued expansion. Bioprint machine contains a computer file with 3D coordinates of a real ear scan. In the model that is built, ear cells are replaced by a silicone gel to form the shape of an ear. A future in which the damaged parts will be repaired digitally. At the moment it is easy bioprint amorphous cartilage with no internal structure and vascularization. Some argue that bioprint tissues will not be connected to real tissue. But bioprint tissue is so accurate that connects quickly to blood vessels of the body, blood and oxygen.

BIOIMPRESION

En el Annual Meeting of the American Association for the Advancement of Science (Washington/USA), una de las estrellas es el bioprinting. Hod Lipson profesor de la Universidad de Cornell, mostro un video en el que se muestra como se elabora e imprime piel y orejas humanas en 3D, esperándose construir mas adelante : huesos, higado, cartilagos y la totalidad del cuerpo humano linea por línea, capa por capa. Otra aplicación del bioprinting es la elaboración de alimentos y la realización de experimentos biologicos. La piel producida por bioprinting ayudara a muchos quemados, ya que el 30% de heridas de guerra compromete la piel. Hod Lipson, tiene un proyecto bien establecido (Lab@Home), en expansión continua. La maquina bioprint contiene un computer file con coordenadas en 3D del scan real de una oreja. En el modelo que se construye, las celulas reales son reemplazadas por un gel de silicona a fin de bioimprimir la forma. Un futuro en el que las partes dañadas seran reparadas digitalmente. De momento es fácil bioimprimir cartilagos amorfos, sin estructura interna y vascularizacion. Algunos arguyen que los tejidos bioimprimidos no se conectaran al tejido real. Empero el tejido bioimprimido es tan exacto que se conecta rápidamente a vasos sanguíneos corporales, sangre y oxigeno.
