Desde que se describi\u00f3 por primera vez, se han llevado a cabo varios estudios, principalmente <em>in vitro<\/em>, ya que <em>in vivo<\/em> sigue siendo un fen\u00f3meno poco estudiado. A medida que los avances tecnol\u00f3gicos traen nuevas herramientas para probar la rigidez de la MEC en tejidos vivos, es probable que surjan nuevos roles para explicar y observar la <em>durotaxis in vivo<\/em>.<\/p>\n<p>La <em>durotaxis<\/em> es normalmente positiva, las c\u00e9lulas de desplazan hacia regiones de mayor rigidez, pero tambi\u00e9n se ha observado en negativo, de zonas r\u00edgidas a blandas, ejemplos de ello se explican en esta <a href=\"https:\/\/www.sciencedirect.com\/science\/article\/pii\/S0960982220304218?dgcid=author\" target=\"_blank\" rel=\"noopener noreferrer\">pieza<\/a> publicada en la revista\u00a0<em>Current Biology.<\/em><\/p>\n<p>En este art\u00edculo, escrito por Xavier Trepat y Raimon Sunyer ofrecen una visi\u00f3n general sobre los m\u00e9todos utilizados para estudiar la <em>durotaxis<\/em> tanto <em>in vitro<\/em> como<em> in vivo,<\/em> y sobre el estado del arte de los mecanismos que gu\u00edan la <em>durotaxis<\/em>, que sigue sin conocerse en su totalidad.<\/p>\n<p>Los investigadores tambi\u00e9n explican que algunos tipos de c\u00e9lulas no muestran <em>durotaxis<\/em> significativa cuando migran de forma aislada, pero s\u00ed cuando act\u00faan como grupos cohesionados. Los grupos multicelulares pueden comportarse como una s\u00faper c\u00e9lula gigante, aumentando su sensibilidad a los gradientes mec\u00e1nicos. Sin embargo, la <em>durotaxis<\/em> colectiva a\u00fan no se ha demostrado <em>in vivo<\/em>, pero se cree que este fen\u00f3meno podr\u00eda guiar la migraci\u00f3n colectiva en procesos patol\u00f3gicos que implican cambios locales en la rigidez del tejido. Por ejemplo, es sabido que los tumores s\u00f3lidos son m\u00e1s r\u00edgidos que el tejido circundante, lo que puede favorecer o prevenir la invasi\u00f3n colectiva.<\/p>\n<p>A modo de conclusi\u00f3n, los investigadores afirman que la <em>durotaxis<\/em> est\u00e1 emergiendo como un mecanismo robusto para impulsar la migraci\u00f3n dirigida de c\u00e9lulas individuales y en grupos. Los componentes clave incluyen la adhesi\u00f3n c\u00e9lula-MEC a trav\u00e9s de agarres moleculares, la transmisi\u00f3n de fuerza de largo alcance a trav\u00e9s del citoesqueleto y las uniones c\u00e9lula-c\u00e9lula. Adem\u00e1s, se espera que la <em>durotaxis<\/em> sea la causa de muchos movimientos migratorios<em> in vivo<\/em> que actualmente no se explican.<\/p>\n<hr \/>\n<p><strong>Reference article<\/strong>: Raimon Sunyer; Xavier Trepat,\u00a0<a href=\"https:\/\/www.sciencedirect.com\/science\/article\/pii\/S0960982220304218?dgcid=author\" target=\"_blank\" rel=\"noopener noreferrer\">Durotaxis<\/a>.\u00a0<em>Current Biol.\u00a0<\/em>2020, 30, R383-R387<\/p>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<h3><img decoding=\"async\" class=\"alignnone size-full wp-image-74024 lazyload\" data-src=\"http:\/\/www.ibecbarcelona.eu\/wp-content\/uploads\/2020\/05\/durotaxis_IBEC_Web.jpg\" alt=\"\" width=\"500\" height=\"304\" data-srcset=\"https:\/\/ibecbarcelona.eu\/wp-content\/uploads\/2020\/05\/durotaxis_IBEC_Web.jpg 500w, https:\/\/ibecbarcelona.eu\/wp-content\/uploads\/2020\/05\/durotaxis_IBEC_Web-300x182.jpg 300w, https:\/\/ibecbarcelona.eu\/wp-content\/uploads\/2020\/05\/durotaxis_IBEC_Web-150x91.jpg 150w\" data-sizes=\"(max-width: 500px) 100vw, 500px\" src=\"data:image\/svg+xml;base64,PHN2ZyB3aWR0aD0iMSIgaGVpZ2h0PSIxIiB4bWxucz0iaHR0cDovL3d3dy53My5vcmcvMjAwMC9zdmciPjwvc3ZnPg==\" style=\"--smush-placeholder-width: 500px; --smush-placeholder-aspect-ratio: 500\/304;\" \/>Xavier Trepat, l\u00edder del grupo de \u00bb Din\u00e1mica integrativa de c\u00e9lulas y tejidos\u00bb en el IBEC junto con Raimon Sunyer, investigador s\u00e9nior en el laboratorio de Trepat, han escrito un Primer en la revista Current Biology sobre la \u00abDurotaxis\u00bb, un mecanismo de migraci\u00f3n celular que podr\u00eda tener un papel en varias enfermedades que impliquen el endurecimiento de los tejidos.<\/h3>\n<p>El desarrollo embrionario, la progresi\u00f3n tumoral o la respuesta inmunol\u00f3gica contra pat\u00f3genos requiere la migraci\u00f3n celular. <\/p>\n","protected":false},"author":4,"featured_media":74024,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[97],"tags":[996,1144],"post_formats":[],"class_list":["post-74029","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-noticias-de-investigacion","tag-tumor","tag-xavier-trepat-es"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.4 - https:\/\/yoast.com\/product\/yoast-seo-wordpress\/ -->\n<title>Investigadores del IBEC explican la &quot;Durotaxis&quot;, un mecanismo de migraci\u00f3n celular con un papel potencial en varias enfermedades - Institute for Bioengineering of Catalonia<\/title>\n<meta name=\"robots\" content=\"index, follow, max-snippet:-1, max-image-preview:large, max-video-preview:-1\" \/>\n<link rel=\"canonical\" href=\"https:\/\/ibecbarcelona.eu\/es\/investigadores-del-ibec-explican-la-durotaxis-un-mecanismo-de-migracion-celular-con-un-papel-potencial-en-varias-enfermedades\/\" \/>\n<meta property=\"og:locale\" content=\"es_ES\" \/>\n<meta property=\"og:type\" content=\"article\" \/>\n<meta property=\"og:title\" content=\"Investigadores del IBEC explican la &quot;Durotaxis&quot;, un mecanismo de migraci\u00f3n celular con un papel potencial en varias enfermedades - Institute for Bioengineering of Catalonia\" \/>\n<meta property=\"og:description\" content=\"Xavier Trepat, l\u00edder del grupo de &quot; Din\u00e1mica integrativa de c\u00e9lulas y tejidos&quot; en el IBEC junto con Raimon Sunyer, investigador s\u00e9nior en el laboratorio de Trepat, han escrito un Primer en la revista Current Biology sobre la &quot;Durotaxis&quot;, un mecanismo de migraci\u00f3n celular que podr\u00eda tener un papel en varias enfermedades que impliquen el endurecimiento de los tejidos.
