The small intestine is composed of crypt-villus structures, whereas in the colon crypts are connected to a smooth surface. Intestinal Stem Cells (ISC) are characterized by the expression of the Wnt target gene Lgr5 and are located at the bottom of the crypts. Elegant fate mapping studies have shown that during steady state Lgr5 ISCs are located at the apex of the cellular hierarchy. Upon injury remaining intestinal epithelial cells are reprogramed into a fetal-like state in order to facilitate regeneration, subsequently seeding a new population of ISCs via dedifferentiation. How this process is orchestrated at the cellular and molecular level remains poorly understood. We previously shown that cells in the fetal intestinal epithelium prior to functionalization and maturation can shift between seemingly differentiated and stem cell phenotypes. The results of this recent work showing that differentiated-like cells are extremely plastic and able to de novo generate stem cells have inspired us in order to develop an innovative research program that aims to use and expand on this knowledge in order to develop intestinal regenerative therapies. In particular we aim to improve quality of life for cancer survivors, which suffer side effects of radiotherapy including an acute and chronic inflammation of the intestine. In order to achieve this goal, we study the cellular and molecular mechanisms involved in epithelial recovery after radiation injury. Furthermore, we study the establishment of the chronic radiation-induced enteritis with a particular attention to the epithelial-immune cell crosstalk. In this IDIBELL seminar we will show the basis of our ambitious research program and we will discuss some preliminary data.<\/p>\n","protected":false},"featured_media":15747,"template":"","meta":{"site-sidebar-layout":"default","site-content-layout":"default","ast-site-content-layout":"","site-content-style":"default","site-sidebar-style":"default","ast-global-header-display":"","ast-banner-title-visibility":"","ast-main-header-display":"","ast-hfb-above-header-display":"","ast-hfb-below-header-display":"","ast-hfb-mobile-header-display":"","site-post-title":"","ast-breadcrumbs-content":"","ast-featured-img":"","footer-sml-layout":"","theme-transparent-header-meta":"default","adv-header-id-meta":"","stick-header-meta":"default","header-above-stick-meta":"","header-main-stick-meta":"","header-below-stick-meta":"","astra-migrate-meta-layouts":"default","ast-page-background-enabled":"default","ast-page-background-meta":{"desktop":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"ast-content-background-meta":{"desktop":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}}},"tags":[313],"class_list":["post-15746","agenda","type-agenda","status-publish","has-post-thumbnail","hentry","tag-regenerativemedicine"],"publishpress_future_workflow_manual_trigger":{"enabledWorkflows":[]},"_links":{"self":[{"href":"https:\/\/idibell.cat\/en\/wp-json\/wp\/v2\/agenda\/15746","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/idibell.cat\/en\/wp-json\/wp\/v2\/agenda"}],"about":[{"href":"https:\/\/idibell.cat\/en\/wp-json\/wp\/v2\/types\/agenda"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/idibell.cat\/en\/wp-json\/wp\/v2\/media\/15747"}],"wp:attachment":[{"href":"https:\/\/idibell.cat\/en\/wp-json\/wp\/v2\/media?parent=15746"}],"wp:term":[{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/idibell.cat\/en\/wp-json\/wp\/v2\/tags?post=15746"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
