Coexpression of acidic fibroblast growth factor enhances specific productivity and antibody titers in transiently transfected HEK293 cells

Florian Maria Wurm, Gaurav Backliwal, Sébastien Chenuet

Recombinant proteins are of great commercial and scientific interest. However, most current production methods using mammalian cells involve the time- and labor-intensive step of creating stable cell lines. Although production methods based on transient ge ...

A novel cell culture approach for tissue engineering based on surface expansion

Hicham Majd

Most tissue engineering approaches include the delivery of reparative cells to a damaged host tissue. Generally these cells are sought to be of a stem cell character since they retain a high potential for proliferation and differentiation into diverse phen ...

Role of BMP signalling in the developing pancreas

The pancreas is an organ of endodermal origin. It is composed of two different tissues; exocrine (acini and ducts) and endocrine (islet of Langerhans). The Bone Morphogenetic Proteins (BMP) are secreted growth factors from the TGFβ superfamily. These prote ...

Rational vector design and multi-pathway modulation of HEK 293E cells yield recombinant antibody titers exceeding 1 g/l by transient transfection under serum-free conditions

Florian Maria Wurm, Gaurav Backliwal, Sébastien Chenuet, Sarah Wulhfard

Transient transfection allows for fast production of recombinant proteins. However, the current bottlenecks in transient transfection are low titers and low specific productivity compared to stable cell lines. Here, we report an improved transient transfec ...

Reduction of brain metastases in plasminogen activator inhibitor-1 deficient mice with transgenic ocular tumors

Friedrich Beermann

Plasminogen activator inhibitor-1 is known to play a paradoxical positive role in tumor angiogenesis, but its contribution to metastatic spread remains unclear. We studied the impact of PAI-1 deficiency in a transgenic mouse model of ocular tumors originat ...

Enzymatic formation of modular cell-instructive fibrin analogs for tissue engineering

Matthias Lütolf, Jeffrey Alan Hubbell, Martin Ehrbar

The molecular engineering of cell-instructive artificial extracellular matrices is a powerful means to control cell behavior and enable complex processes of tissue formation and regeneration. This work reports on a novel method to produce such smart biomat ...

Expression of FGF-2 in neural progenitor cells enhances their potential for cellular brain repair in the rodent cortex

Didier Trono, Marc-Olivier Sauvain, Michiko Kanemitsu

Strategies to enhance the capacity of grafted stem/progenitors cells to generate multipotential, proliferative and migrating pools of cells in the postnatal brain could be crucial for structural repair after brain damage. We investigated whether the over-e ...

Corneal epithelial cell fate is maintained during repair by Notch1 signaling via the regulation of vitamin A metabolism

Freddy Radtke, Yann Barrandon

Integrity and preservation of a transparent cornea are essential for good vision. The corneal epithelium is stratified and nonkeratinized and is maintained and repaired by corneal stem cells. Here we demonstrate that Notch1 signaling is essential for cell ...

FGF signaling is necessary for establishing gut tube domains along the anterior-posterior axis in vivo

Anne Grapin-Botton

At the end of gastrulation in avians and mammals, the endoderm germ layer is an undetermined sheet of cells. Over the next 24-48 h, endoderm forms a primitive tube and becomes regionally specified along the anterior-posterior axis. Fgf4 is expressed in gas ...

Oncogenic steroid receptor coactivator-3 is a key regulator of the white adipogenic program

Johan Auwerx

The white adipocyte is at the center of dysfunctional regulatory pathways in various pathophysiological processes, including obesity, diabetes, inflammation, and cancer. Here, we show that the oncogenic steroid receptor coactivator-3 (SRC-3) is a critical ...
