Three‐dimensional migration of human amniotic fluid stem cells involves mesenchymal and amoeboid modes and is regulated by mTORC1

by rss feed | Dec 5, 2021 | News Feeds, TISSUE‐SPECIFIC STEM CELLS

This study on human amniotic fluid stem cells (hAFSCs) provides the first demonstration that human stem cells exhibit mTORC1-dependent invasive capacity and can concurrently make use of mesenchymal and amoeboid 3D cell migration modes. These results represent an...

Aryl hydrocarbon receptor controls skin homeostasis, regeneration, and hair follicle cycling by adjusting epidermal stem cell function

by rss feed | Dec 5, 2021 | News Feeds, TISSUE‐SPECIFIC STEM CELLS

Aryl hydrocarbon receptor (AhR) is required for skin homeostasis and hair growth. AhR depletion in keratinocytes and dermal fibroblasts compromises skin regeneration likely because of reduced epidermal stem cells (EpdSCs) numbers. Reconstitution assays suggest a cell...

Dopamine regulates adult neurogenesis in the ventricular‐subventricular zone via dopamine D3 angiotensin type 2 receptor interactions

by rss feed | Dec 5, 2021 | News Feeds, TISSUE‐SPECIFIC STEM CELLS

Model of the effects of dopamine in the proliferation of ventricular-subventricular zone cells. Dopamine, via D2-like receptors, upregulates angiotensin AT2 receptor expression, which mediates D2-induced cell proliferation. Dopamine, through D1-like receptors,...

ELF3 mediates IL‐1α induced differentiation of mesenchymal stem cells to inflammatory iCAFs

by rss feed | Dec 5, 2021 | News Feeds, TISSUE‐SPECIFIC STEM CELLS

Mesenchymal stem cells are a progenitor of myofibroblasts and inflammatory carcinoma-associated fibroblasts. The present study identifies ELF3 as an essential transcription factor in the differentiation of this key pro-inflammatory stromal cell type. Abstract Stromal...

Spatiotemporal extracellular matrix modeling for in situ cell niche studies
