Identification of epidermal pdx1 expression discloses different roles of notch1 and notch2 in murine kras-induced skin carcinogenesis in vivo

BACKGROUND: The Ras and Notch signaling pathways are frequently activated during development to control many diverse cellular processes and are often dysregulated during tumorigenesis. To study the role of Notch and oncogenic Kras signaling in a progenitor ...

Use of Force Spectroscopy to Investigate the Adhesion of Living Adherent Cells

Nicolas Blondiaux, Harry Heinzelmann, Mona Julia Katharina Klein, Raphaël Pugin, Martha Liley

The use of force spectroscopy to study the adhesion of living fibroblasts to their culture substrate was investigated. Both primary fibroblasts (PEMF) and a continuous cell line (3T3) were studied on quartz surfaces. Using a fibronectin- coated AFM cantile ...

Rat bladder muscle regeneration induced by local delivery of an engineered insulin-like growth factor 1 in fibrin gels

Lirong Yang

Currently, both congenital abnormalities and developmental problems of the bladder in children, and other dysfunctions in adults, require reconstructive surgery. Such correction involves transplant action of native tissues (such as gastrointestinal segment ...

Epithelial-Mesenchymal Transition-Derived Cells Exhibit Multi-Lineage Differentiation Potential Similar to Mesenchymal Stem Cells

Cathrin Brisken, Ayyakkannu Ayyanan

The epithelial-to-mesenchymal transition (EMT) is an embryonic process that becomes latent in most normal adult tissues. Recently, we have shown that induction of EMT endows breast epithelial cells with stem cell traits. In this report, we have further cha ...

A multichamber fluidic device for 3D cultures under interstitial flow with live imaging: Development, characterization, and applications

Melody Swartz, Jan Overney, James Brandon Dixon, Adrian Chung-Kai Shieh, Carmen Bonvin

Interstitial flow is an important biophysical cue that can affect capillary morphogenesis, tumor cell migration, and fibroblast remodeling of the extracellular matrix, among others. Current models that incorporate interstitial flow and that are suitable fo ...

The 12th-14th type III repeats of fibronectin function as a highly promiscuous growth factor-binding domain

Jeffrey Alan Hubbell, Mikaël Martino

It has recently been shown that some growth factors (GFs) have strong interactions with nonproteoglycan extracellular matrix proteins. Relevant here, the 12th-14th type three repeats of fibronectin (FN III12-14) have been shown to bind insulin-like growth ...

Phosphopantetheinyl transferase-catalyzed formation of bioactive hydrogels for tissue engineering

Kai Johnsson, Matthias Lütolf, Katarzyna Mosiewicz

Synthetic bioactive hydrogels have been widely recognized as key elements of emerging strategies to engineer tissues. However, the current shortage of highly specific and biocompatible methods to form and functionalize these materials hampers their wide ph ...

Mathematical modeling of bone formation inside tissue engineering scaffolds (Master project)

Alireza Roshan Ghias

Tissue engineering scaffolds are porous structures that allow bone cells to reside and produce bone. This process involves migration and differentiation of mesenchymal stromal cells and production of cartilage and bone by chondrocytes and osteoblasts, whic ...

Survey of volatile oxylipins and their biosynthetic precursors in bryophytes

Emmanuel Croisier

Oxylipins are metabolites which are derived from the oxidative fragmentation of polyunsaturated fatty acids. These metabolites play central roles in plant hormonal regulation and defense. Here we survey the production of volatile oxylipins in bryophytes an ...

Development of a medical instrument to induce and control hydrogel polymerization in-situ

Dominique Pioletti, Pierre-Etienne Bourban, Christophe Moser

Background - Nucleus pulposus degeneration is a very common musculo-skeletal pathology, which is in part responsible for low back pain, a pandemic medical problem. Artificial hydrogels are being investigated by research group around the world for the purpo ...
