MetabolomicsVGLL4 modulates Paneth cells and sustains intestinal homeostasis.
Paneth cells are defensive cells in the intestinal tract, which secrete niche factors and antimicrobial peptides (AMPs) to maintain the small intestinal stem cell niche and immune homeostasis. Here, we show that Vestigial-like family member 4 (VGLL4) plays a pivotal role in maintaining small intesti...

MetabolomicsOld mitochondria regulate niche renewal via stem cell metabolism
Cellular metabolism is emerging as a potent regulator of cell fate, raising the possibility that the recently discovered metabolic heterogeneity between newly synthesized and chronologically old organelles may impact stem cell fate in mammalian tissues. The small intestine is maintained by actively ...

TranscriptomicsPaneth cells constitute the niche for Lgr5 stem cells in intestinal crypts
Homeostasis of self-renewing small intestinal crypts results from neutral competition between Lgr5 stem cells, small cycling cells located at crypt bottoms1, 2. Lgr5 stem cells are interspersed between terminally differentiated Paneth cells, that are known to produce bactericidal products such as ly...

MetabolomicsLinking gastrointestinal microbiota and metabolome dynamics to clinical outcomes in pediatric hematopoietic stem cell transplantation

BACKGROUND: Hematopoietic stem cell transplantation is a curative procedure for a variety of conditions. Despite major advances, a plethora of adverse clinical outcomes can develop post-transplantation including graft-versus-host disease and infections, which remain the major cau...

TranscriptomicsSingle intestinal stem cells build crypt-villus structures in vitro without a cellular niche
The intestinal epithelium is the most rapidly self-renewing tissue in adult mammals. We have recently demonstrated the presence of approximately six cycling Lgr5+ stem cells at the bottoms of small intestinal crypts1. We have now established long-term culture conditions under which single crypts und...

MetabolomicsShort-Term Clinical Response and Changes in the Fecal Microbiota and Metabolite Levels in Patients with Crohn's Disease After Stem Cell Infusions
Recent studies have shown a close relationship between the gut microbiota and Crohn's disease (CD). This study aimed to determine whether mesenchymal stem cell (MSC) treatment alters the gut microbiota and fecal metabolite pathways and to establish the relationship between the gut microbiota and fec...

TranscriptomicsTranscription profiling of mouse model of intestinal polyposis PTEN-deficient mutant reveals intestinal stem cells initiate intestinal polyposis
Intestinal polyposis, a precancerous neoplasia, results primarily from an abnormal increase in the number of crypts. Crypts contain intestinal stem cells (ISCs). Thus intestinal polyposis provides an ideal condition for studying stem cell involvement in polyp/tumor formation. Using a conditional kno...

TranscriptomicsTranscription profiling of mouse intestinal cells expressing Lgr5 at high or low levels or with Ascl2 conditionally knocked out shows Ascl2 controls intestinal stem cell fate
The small intestinal epithelium is the most rapidly self-renewing tissue of mammals. Proliferative cells are confined to crypts, while differentiated cell types predominantly occupy the villi. We recently demonstrated the existence of a long-lived pool of cycling stem cells defined by Lgr5 expressio...

TranscriptomicsDistinct processes and transcriptional targets underlie CDX2 requirements in intestinal stem cells and differentiated villus cells
To define target genes of the intestine-restricted transcription factor (TF) CDX2 in intestinal stem cells, we performed chromatin immunoprecipitation coupled with high-throughput sequencing (ChIP-Seq). We used RNA-sequencing to profile gene expression changes during cell differentiation from mouse ...

GenomicsAnalyses of the chromatin and transcriptional basis for lateral inhibition in isolated intestinal epithelial cells.
We analyzed chromatin modifications, DNaseI-hypersensitive sites, and occupancy of a key secretory-lineage transcription factor, ATOH1. We found that lateral inhibition in the intestine occurs through ATOH1 exerting direct control within a broadly permissive chromatin state that is established in st...
