En conjunto, las enfermedades de las v\u00edas respiratorias como el enfisema pulmonar, la bronquitis, el asma y la fibrosis qu\u00edstica son la segunda causa de muerte en todo el mundo. M\u00e1s de 35 millones de estadounidenses sufren de una enfermedad respiratoria cr\u00f3nica y debilitante.
\nCient\u00edficos del Instituto Weizmann en Israel han propuesto una nueva direcci\u00f3n que podr\u00eda, en el futuro, llevar al desarrollo de un m\u00e9todo para aliviar algunos de los sufrimientos que causan estas enfermedades. Los resultados del estudio muestran c\u00f3mo podr\u00eda ser posible utilizar c\u00e9lulas madre embrionarias para reparar el tejido pulmonar da\u00f1ado.<\/p>\n

Un m\u00e9todo existente, las nuevas aplicaciones
\nLa investigaci\u00f3n comenz\u00f3 con una idea: Ciertas c\u00e9lulas madre que residen normalmente en los pulmones son muy similares a las de la m\u00e9dula \u00f3sea. Adem\u00e1s, en cada \u00f3rgano, las c\u00e9lulas madre, en lugar de ser distribuidas por todo el tejido, se concentran en compartimentos especiales que contienen todas las disposiciones que se derivan de las c\u00e9lulas que necesitan para prosperar.
\n\u00abLlegamos a esta conclusi\u00f3n que nos sugiri\u00f3 que podr\u00edamos ser capaces de aplicar nuestros conocimientos de estas t\u00e9cnicas para trasplantes de c\u00e9lulas madre de la m\u00e9dula \u00f3sea para reparar el tejido pulmonar\u00bb, dijo el Prof. Yair Reisner del Departamento de Inmunolog\u00eda del Instituto Weizmann en un comunicado.<\/p>\n

Su investigaci\u00f3n\u00a0mostr\u00f3 que este es el marco de tiempo ideal para cosechar las c\u00e9lulas: las c\u00e9lulas m\u00e1s j\u00f3venes no han completado el proceso de diferenciaci\u00f3n; las c\u00e9lulas m\u00e1s viejas son menos capaces de la regeneraci\u00f3n de pulm\u00f3n.
\nPosteriormente, el equipo llev\u00f3 a cabo una serie de experimentos en los que se borran los compartimentos de c\u00e9lulas madre de los pulmones con un m\u00e9todo que hab\u00edan desarrollado, entonces inyectan las nuevas c\u00e9lulas madre en modelos de rat\u00f3n con da\u00f1o pulmonar. Las c\u00e9lulas madre pulmonares embrionarias se las arreglaron para encontrar su camino a trav\u00e9s de la sangre a los pulmones y establecerse en el compartimento adecuado.<\/p>\n

A las seis semanas, estas c\u00e9lulas se fueron diferenciando y creando tejido pulmonar normal. En los ratones los pulmones da\u00f1ados sanaron y su respiraci\u00f3n mejor\u00f3 significativamente.
\nEl siguiente obst\u00e1culo que enfrenta Reisner, es determinar la dosis correcta de medicamentos que son necesarios para prevenir el rechazo de las c\u00e9lulas trasplantadas, que son necesarias despu\u00e9s de tales procedimientos. \u00abPero nuestra visi\u00f3n real, que fue reforzada por este \u00e9xito\u00bb, expresa Reisner, \u00abes la creaci\u00f3n de un banco de tejido pulmonar que ser\u00e1 un recurso para las c\u00e9lulas madre embrionarias de pulm\u00f3n.\u00bb Este banco podr\u00eda significar que hay una fuente disponible de c\u00e9lulas para la reparaci\u00f3n del da\u00f1o en las personas que padecen la enfermedad respiratoria grave.<\/p>\n

(AP\/Vahid Salemi)","description":"In this Saturday, Feb. 3, 2007 file photo, an Iranian technician works at the Uranium Conversion Facility just outside the city of Isfahan 255 miles (410 kilometers) south of the capital Tehran, Iran. The phrases to describe some of the looming foreign policy challenges for U.S. President Barack Obama didn't even exist when he took the oath of office the first time: the Arab Spring, the Fordo Facility housing Iran's underground uranium enrichment labs, the stealth power of new viruses bearing names such as Stuxnet and Flame in the shadow world of cyber-sabotage. But that also doesn't mean the list of earlier conflicts, stalemates and crises _ inherited by Obama in his first term and, in some cases, reaching back decades _ is any shorter for the White House. Obama has stood by the policy that tightening sanctions and diplomacy is the best course to leverage possible concessions from Iran on its nuclear program, which the West and others fear could eventually lead to atomic weapons. Iran says it only seeks reactors for energy and medical research.(AP Photo\/Vahid Salemi,
