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 ...

Scleractinian coral morphogenesis

Agathe Eliette Marie Lecointe

Metamorphosis is a crucial step in the life cycle of a scleractinian coral: The swimming coral larva, the planula, settles, and metamorphoses into a sessile calcifying primary polyp, which subsequently grows into an adult colony. Importantly, morphogenesis ...

A Sox1 to Pax6 switch drives neuroectoderm to radial glia progression during differentiation of mouse embryonic stem cells

David Michael Suter

The transcription factors Sox1 and Pax6 are expressed sequentially during early mouse embryonic neurogenesis. Sox1 expression starts upon formation of neuroectoderm, whereas Pax6 is subsequently expressed in radial glial cells, the latter giving rise to mo ...

Thymic epithelial cells

Paola Bonfanti

As primary lymphoid organ, the thymus provides the essential environment for maturation and selection of functional T lymphocytes. Thymic epithelial (TE) cells derive from the endoderm, and more specifically, from the third pharyngeal pouch. The thymic epi ...

Epithelial stem cells and mechanical signal transduction

Vincent Bernard Cattin

Hair follicles are cutaneous structures characteristic of mammals. These sensitive organs cycle and contain multipotent epithelial stem cells which are implicated in hair growth and hair cycle. A single whisker follicle of the rat hosts up to 1500 stem cel ...

Evolutionary morphogenesis for multi-cellular systems

Dario Floreano, Daniel Roggen, Diego Federici

With a gene required for each phenotypic trait, direct genetic encodings may show poor scalability to increasing phenotype length. Developmental systems may alleviate this problem by providing more efficient indirect genotype to phenotype mappings. A novel ...

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 ...

A Morphogenetic Evolutionary System: Phylogenesis of the POEtic Circuit

Dario Floreano, Claudio Mattiussi, Daniel Roggen

This paper describes a new evolutionary mechanism developed specifically for cellular circuits. Called morphogenetic system, it is inspired by the mechanisms of gene expression and cell differentiation found in living organisms. It will be used as the phyl ...

Increased transgene expression by the mouse tyrosinase enhancer is restricted to neural crest-derived pigment cells

Friedrich Beermann

In this study, we have addressed the impact of the mouse tyrosinase enhancer on regulated expression from the mouse tyrosinase promoter during embryonic development. Stable and transient transgenic experiments using the reporter gene lacZ reveal that (1) e ...

Patterning signals acting in the spinal cord override the organizing activity of the isthmus

Anne Grapin-Botton

The regionalization of the neural tube along the anteroposterior axis is established through the action of patterning signals from the endo-mesoderm including the organizer. These signals set up a pre-pattern which is subsequently refined through local pat ...
