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 ...

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

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

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 ...

DL4-mediated Notch signaling is required for the development of fetal alpha beta and gamma delta T cells

Freddy Radtke, Ute Koch, Stéphanie Claudinot

T-cell development depends upon interactions between thymocytes and thymic epithelial cells (TECs). The engagement of delta-like 4 (DL4) on TECs by Notch1 expressed by blood-borne BM-derived precursors is essential for T-cell commitment in the adult thymus ...

Capturing epidermal stemness for regenerative medicine

Yann Barrandon, Ariane Rochat, Andrea Zaffalon, François Gorostidi, Stéphanie Claudinot, 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 ...

Generation and characterization of a Notch1 signaling-specific reporter mouse line

Freddy Radtke, Yann Barrandon, Rajwinder Lehal, Stéphanie Claudinot, Luca Pellegrinet

Signaling through the Notch1 receptor is essential for the control of numerous developmental processes during embryonic life as well as in adult tissue homeostasis and disease. Since the outcome of Notch1 signaling is highly context-dependent, and its prec ...

Sox10 promotes the formation and maintenance of giant congenital naevi and melanoma

Yann Barrandon, Friedrich Beermann, Stéphanie Claudinot, Lukas Sommer

Giant congenital naevi are pigmented childhood lesions that frequently lead to melanoma, the most aggressive skin cancer. The mechanisms underlying this malignancy are largely unknown, and there are no effective therapies. Here we describe a mouse model fo ...

Microenvironmental reprogramming of thymic epithelial cells to skin multipotent stem cells

Yann Barrandon, Stéphanie Claudinot, Alessandro Wataru Amici, Paola Bonfanti

The thymus develops from the third pharyngeal pouch of the anterior gut and provides the necessary environment for thymopoiesis (the process by which thymocytes differentiate into mature T lymphocytes) and the establishment and maintenance of self-toleranc ...
