Sensing Tip with Electrical Impedance Sensor

Philippe Renaud, Yann Barrandon, David Vincent Bonzon

The invention relates to a sensing tip (8) comprising a conventional tip (1), such as a pipette tip, which is essentially made of a cavity which communicates with the external environment through an aperture (3) located at the tip distal end; the sensing t ...

A single epidermal stem cell strategy for safe ex vivo gene therapy

Graham Knott, Jacques Rougemont, Yann Barrandon, Ariane Rochat, Andrea Zaffalon, Nicolas Grasset, Stéphanie Danièle Hélène Droz-Georget, Sara Benmohammed, Emmanuelle Savioz-Dayer, Alessandra Recchia

There is a widespread agreement from patient and professional organisations alike that the safety of stem cell therapeutics is of paramount importance, particularly for ex vivo autologous gene therapy. Yet current technology makes it difficult to thoroughl ...

Cell motion predicts human epidermal stemness

Yann Barrandon

Image-based identification of cultured stem cells and noninvasive evaluation of their proliferative capacity advance cell therapy and stem cell research. Here we demonstrate that human keratinocyte stem cells can be identified in situ by analyzing cell mot ...

LRIG1 inhibits STAT3-dependent inflammation to maintain corneal homeostasis

Yann Barrandon, Andrea Zaffalon

Corneal integrity and transparency are indispensable for good vision. Cornea homeostasis is entirely dependent upon corneal stem cells, which are required for complex wound-healing processes that restore corneal integrity following epithelial damage. Here, ...

Clonal, Self-Renewing and Differentiating Human and Porcine Urothelial Cells, a Novel Stem Cell Population

Yann Barrandon, Peter Frey, Jeffrey Alan Hubbell, Hans Mattias Larsson, François Gorostidi

Although urothelial progenitor-like cells have been described in the human urinary tract, the existence of stem cells remains to be proven. Using a culture system that favors clonogenic epithelial cell growth, we evaluated and characterized clonal human ur ...

Recent advances in the epidermal growth factor receptor/ligand system biology on skin homeostasis and keratinocyte stem cell regulation

Yann Barrandon

The epidermal growth factor (EGF) receptor/ligand system stimulates multiple pathways of signal transduction, and is activated by various extracellular stimuli and inter-receptor crosstalk signaling. Aberrant activation of EGF receptor (EGFR) signaling is ...

Corneal Endothelial Cell Fate Is Maintained by LGR5 Through the Regulation of Hedgehog and Wnt Pathway

Yann Barrandon

Leucine-rich repeat-containing G protein-coupled receptor 5 (LGR5), a target of Wnt signaling, is reportedly a marker of intestine, stomach, and hair follicle stem cells in mice. To gain a novel insight into the role of LGR5 in human corneal tissue, we per ...

Actin filament dynamics impacts keratinocyte stem cell maintenance

Yann Barrandon

Cultured human epidermal keratinocyte stem cells (holoclones) are crucial for regenerative medicine for burns and genetic disorders. In serial culture, holoclones progressively lose their proliferative capacity to become transient amplifying cells with lim ...
