- Notch signaling is essential for maintaining intestinal stem cell activity and directing epithelial cell fate. Paneth cells have been proposed to be niche cells, providing Notch signal to neighboring stem cells through expression of the key Notch ligands DLL1 and DLL4. However, intestinal stem cells persist in the absence of Paneth cells. Here, we used genetic mouse models to clarify the role of Paneth cell-derived Notch ligands for stem cell function. Paneth cell-specific deletion of and resulted in loss of crypt base stem cells, with no effect on overall crypt cell proliferation. Organoid growth was reduced in knockout mice, suggesting reduced stem cell function. Upon irradiation injury, stem cell return and crypt regeneration were significantly impaired in the Notch ligand-deleted mice. These findings suggest that Paneth cell-derived Notch ligands DLL1 and DLL4 are crucial for crypt base stem cell maintenance and for crypt regeneration after injury. - Source: PubMed

Gao WentaoHou YangfengLiu JiaxingHo Cheng KiuCheng Alfred Sze-LokWaldmann HermanZhou BinLau James Y WLui Kathy O - The Notch signalling pathway regulates cell fate, proliferation, and differentiation and consists of receptors (Notch1-4), ligands (JAG1-2, DLL1, DLL3-4), and downstream targets. Altered expression of Notch pathway-linked genes has been reported in multiple cancers, although their associations with survival may vary according to tumour type. Their relationship with biological sex and radiotherapy (RT) has been less extensively explored. - Source: PubMed

O'Hea HelenBourbonne VMarignol Laure - Understanding the regulation of hematopoietic stem and progenitor cell (HSPC) fate and translating it into effective culture strategies remains a significant challenge. Asymmetric lysosomal inheritance during HSPC division has been shown to predict variations in daughter cell activity and fate, yet the underlying regulators remain unclear. Through cell-cell communication analysis of bone marrow single-cell sequencing data, we identified the Notch ligand Delta-like protein 1 (DLL1) as a potential regulator in HSPC asymmetric division (ACD). Interactions between DLL1-presenting microparticles (MP-Ds) and HSPCs were observed in addressable microwell arrays, simulating cellular responses to localized niche signals. Long-term single-cell tracking revealed that MP-D interactions polarized HSPC lysosomes toward the contact site, directing division orientation and consequent asymmetric lysosomal inheritance in paired daughter cells. Furthermore, this co-culture system enhanced long-term hematopoietic reconstitution capacity of HSPCs in serial transplantations. Our findings support an association between HSPC ACD and the presentation mode of DLL1 signals, which enhances the ex vivo maintenance of HSPCs. - Source: PubMed
