ratones espinosos africanos el Acomys kempi y Acomys<\/em><\/strong> percivali,los primeros mam\u00edferos capaces de regenerar al completo su tejido da\u00f1ado al completo.<\/p>\n\n\n\nEstos roedores tienen una piel d\u00e9bil que se rasga f\u00e1cilmente, ya que esto les ayuda a escapar de los depredadores. Los ratones se desprenden de su piel cuando son atacados o mordidos, logrando as\u00ed huir en el acto y dejar entre las garras buena parte de su pellejo, que es algo menos resistente que el de los ratones comunes.<\/p>\n\n\n\n
De acuerdo a investigadores estos animales son capaces de regenerar<\/strong> la totalidad de su piel, las gl\u00e1ndulas sudor\u00edparas, el pelaje e incluso los cart\u00edlagos sin dejar cicatriz.<\/p>\n\n\n\nPese a que la regeneraci\u00f3n de tejidos no es algo nuevo en el reino animal, es algo habitual en algunos insectos, reptiles y anfibios, nunca se hab\u00eda dado en los mam\u00edferos. Algunas lagartijas pueden volver a crecer sus colas, mientras que el pez cebra es capaz de regenerar diversos \u00f3rganos, como el coraz\u00f3n.<\/p>\n\n\n\n
Motivos de la regeneraci\u00f3n<\/h3>\n\n\n\n
El descubrimiento de este rat\u00f3n se produjo en 2012, lo que abri\u00f3 una nueva v\u00eda de investigaci\u00f3n en la medicina molecular. Adem\u00e1s, seg\u00fan los investigadores es pr\u00e1cticamente imposible que los ratones hayan desarrollado un nuevo mecanismo gen\u00e9tico de regeneraci\u00f3n.<\/p>\n\n\n\n
Se ha demostrado que estos peque\u00f1os roedores son capaces de regenerar sus tejidos gracias al blastema<\/strong>, un conjunto de c\u00e9lulas madre que tambi\u00e9n utilizan otros animales, como las salamandras, para reconstruir las partes que faltan de su cuerpo.<\/p>\n\n\n\nLa directora del estudio, Ashley Seifert, sostiene que lo m\u00e1s probable es que los genes que dirigen la regeneraci\u00f3n en otros animales se hayan vuelto a activar en estos mam\u00edferos.<\/p>\n","protected":false},"excerpt":{"rendered":"
