Low temperature and mTOR inhibition favor stem cell maintenance in human keratinocyte cultures

Kai Johnsson, Yann Barrandon, Johannes Alexander Mosig, Thomas Michael Braschler, Ariane Rochat, Jean-Baptiste Bureau, Fahd Azzabi Zouraq, Mako Kamiya

Adult autologous human epidermal stem cells can be extensively expanded ex vivo for cell and gene therapy. Identifying the mechanisms involved in stem cell maintenance and defining culture conditions to maintain stemness is critical, because an inadequate ...

Tp63-expressing adult epithelial stem cells cross lineages boundaries revealing latent hairy skin competence

Yann Barrandon, Ariane Rochat, Stéphanie Claudinot, Paola Bonfanti, Daniel-Alexandre Littman, Christèle Gonneau

The formation of hair follicles, a landmark of mammals, requires complex mesenchymal-epithelial interactions and it is commonly believed that embryonic epidermal cells are the only cells that can respond to hair follicle morphogenetic signals in vivo. Here ...

Traceable Impedance-Based Dispensing and Cloning of Living Single Cells

Philippe Renaud, Yann Barrandon, Ariane Rochat, David Vincent Bonzon, Stéphanie Claudinot, Georges Muller

Single-cell cloning is essential in stem cell biology, cancer research, and biotechnology. Regulatory agencies now require an indisputable proof of clonality that current technologies do not readily provide. Here, we report a one-step cloning method using ...

Pore Size Manipulation in 3D Printed Cryogels Enables Selective Cell Seeding

Philippe Renaud, Arnaud Bertsch, Thomas Michael Braschler, Ariane Rochat, Amélie Barbara Hildegarde Béduer, Ludovic Serex, Aleksandra Filippova

Cryogels are macroporous materials that display remarkable properties, such as high pore interconnection, large surface to volume ratio, and high mechanical stability, making them good candidates for 3D cell culture. However, shaping cryogels remains chall ...

Additive manufacturing of hierarchical injectable scaffolds for tissue engineering

Philippe Renaud, Niccolo Piacentini, Thomas Michael Braschler, Ariane Rochat

We present a 3D-printing technology allowing free-form fabrication of centimetre-scale injectable structures for minimally invasive delivery. They result from the combination of 3D printing onto a cryogenic substrate and optimisation of carboxymethylcellul ...

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 ...

Wiley Open Access2015

Capturing epidermal stemness for regenerative medicine

Yann Barrandon, Ariane Rochat, François Gorostidi, Stéphanie Claudinot, Andrea Zaffalon, Nicolas Grasset, Stéphanie Danièle Hélène Droz-Georget

The skin is privileged because several skin-derived stem cells (epithelial stem cells from epidermis and its appendages, mesenchymal stem cells from dermis and subcutis, melanocyte stem cells) can be efficiently captured for therapeutic use. Main indicatio ...

Oligopotent stem cells are distributed throughout the mammalian ocular surface

Yann Barrandon, Ariane Rochat, Georges Abou Jaoudé

The integrity of the cornea, the most anterior part of the eye, is indispensable for vision. Forty- five million individuals worldwide are bilaterally blind and another 135 million have severely impaired vision in both eyes because of loss of corneal trans ...

Neural crest-derived cells with stem cell features can be traced back to multiple lineages in the adult skin

Yann Barrandon, Friedrich Beermann, Ariane Rochat, Lukas Sommer

Given their accessibility, multipotent skin-derived cells might be useful for future cell replacement therapies. We describe the isolation of multipotent stem cell-like cells from the adult trunk skin of mice and humans that express the neural crest stem c ...
