Live-cell imaging in human colonic monolayers reveals ERK waves limit the stem cell compartment to maintain epithelial homeostasis

eLife, 2022
The establishment and maintenance of different cellular compartments in tissues is a universal requirement across all metazoans. Maintaining the correct ratio of cell types in time and space allows tissues to form patterned compartments and perform ...

Regional differences in store-operated Ca2+ entry in the epithelium of the intact human lens [PDF]

, 2009
An elevated level of Ca2+ is an important factor in cataract, yet precisely how Ca2+ enters the lens is unknown. Lens epithelial cells contain a range of G-protein–coupled receptors and receptor tyrosine kinases that induce increases in intracellular Ca2+

Incidence and Outcome of Infants With Cancer in Canada: A Report From Cancer in Young People in Canada Database

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Purpose Infants with cancer are rare and face unique challenges. Our study aims to describe the incidence of infantile cancers in Canada and to compare treatment‐related mortality (TRM) and their outcomes with those of older children. Methods We conducted a retrospective cohort study using the Cancer in Young People in Canada database ...

The epithelium of the dorsal marginal zone of Xenopus has organizer properties [PDF]

, 1992
We have investigated the properties of the epithelial layer of the dorsal marginal zone (DMZ) of the Xenopus laevis early gastrula and found that it has inductive properties similar to those of the entire Spemann organizer.

Oncogenic NRAS Mutation in Incipient Sarcomatous Transformation of Cystic Nephroma From a Patient With DICER1‐Related Tumor Predisposition Syndrome

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Anaplastic sarcoma of the kidney (ASK) is a DICER1‐associated malignant tumor presumed to arise in a benign precursor, pediatric cystic nephroma (PCN). However, the initial oncogenic alteration(s) associated with malignant transformation are unknown.

Enteropathogenic E. coli shows delayed attachment and host response in human jejunum organoid‐derived monolayers compared to HeLa cells

FEBS Letters, EarlyView.
Enteropathogenic E. coli (EPEC) infects the human intestinal epithelium, resulting in severe illness and diarrhoea. In this study, we compared the infection of cancer‐derived cell lines with human organoid‐derived models of the small intestine. We observed a delayed in attachment, inflammation and cell death on primary cells, indicating that host ...
