The Delivery of alpha 1-Antitrypsin Therapy Through Transepidermal Route: Worthwhile to Explore

Florian Maria Wurm

Human alpha 1-antitrypsin (AAT) is an abundant acute phase glycoprotein expressing anti-protease and immunomodulatory activities, and is used as a biopharmaceutical to treat patients with inherited AAT deficiency. The pleiotropic properties of AAT provide ...

Method and system for analysis of organic material by auto-cathodoluminescence

Hans Mattias Larsson, Marcin Stefan Zielinski

Analyzing isolated collagen gel samples of a rat-tail and bovine hide, we demonstrated in situ detection of spectrally deconvoluted auto-cathodoluminescence signatures of specific molecular content with precise spatial localization over a maximum field of ...

From the early steps of whisker formation to its evolutionary disappearance: the (curious) case of Prdm1 and its regulation

Pierluigi Giuseppe Manti

Whiskers (also known as vibrissae) are sensory organs that are thought to have first appeared in Therapsida, a group of synapsids that includes mammals and evolutionary ancestors like the Thrinaxodon(1). They are highly conserved among mammals to the notab ...

The Nano-Scale Mechanical Properties of the Extracellular Matrix Regulate Dermal Fibroblast Function

Jean-Jacques Meister, Boris Hinz, Lara Buscemi Estefanell, Josiane Angèle Charlotte Smith-Clerc

Changes in the mechanical properties of dermis occur during skin aging or tissue remodeling and affect the activity of resident fibroblasts. With the aim to establish elastic culture substrates that reproduce the variable softness of dermis, we determined ...

Real-time Full Field Laser Doppler Imaging

Theo Lasser, Marcel Leutenegger, Tyler Nerton Thacher

We present a full field laser Doppler imaging instrument that enables real-time in vivo assessment of blood flow in dermal tissue and skin. The instrument monitors the blood perfusion in an area of about 50cm2 with 480 x 480 pixels per frame at a rate of 1 ...

Engineered aprotinin for improved stability of fibrin biomaterials

Jeffrey Alan Hubbell, Peter Frey, Stephane Kontos, Kristen Lorentz

Fibrin has been long used clinically for hemostasis and sealing, yet extension of use in other applications has been limited due to its relatively rapid resorption in vivo, even with addition of aprotinin or other protease inhibitors. We report an engineer ...

Dermal collagen and lipid deposition correlate with tissue swelling and hydraulic conductivity in murine primary lymphedema

Melody Swartz, Joseph Rutkowski

Primary lymphedema is a congenital pathology of dysfunctional lymphatic drainage characterized by swelling of the limbs, thickening of the dermis, and fluid and lipid accumulation in the underlying tissue. Two mouse models of primary lymphedema, the Chy mo ...

Acquisition et recalage informatique d'images confocales de tissus denses : application à l'étude de la papille folliculaire de vibrisse de souris

Nicolas Fête

Analysis of the 3D structure of a biological sample is an important step to model cell and tissue dynamics. As a model system, we set up to determine the number of nuclei in a follicular papilla using confocal imaging and 3D computer reconstruction. The fo ...

Control of thrombin signaling through PI3K is a mechanism underlying plasticity between hair follicle dermal sheath and papilla cells

Yann Barrandon

In hair follicles, dermal papilla (DP) and dermal sheath (DS) cells exhibit striking levels of plasticity, as each can regenerate both cell types. Here, we show that thrombin induces a phosphoinositide 3-kinase (PI3K)-Akt pathway-dependent acquisition of D ...

Mechanisms of interstitial flow-induced remodeling of fibroblast-collagen cultures

Melody Swartz

Interstitial fluid flow, critical for macromolecular transport, was recently shown to drive fibroblast differentiation and perpendicular cell and matrix alignment in 3D collagen cultures. Here we explore the mechanisms underlying this flow-induced cell and ...

Molecularly engineered PEG hydrogels: A novel model system for proteolytically mediated cell migration

Matthias Lütolf, Jeffrey Alan Hubbell

Model systems mimicking the extracellular matrix (ECM) have greatly helped in quantifying cell migration in three dimensions and elucidated the mol. determinants of cellular motility in morphogenesis, regeneration, and disease progression. Here the authors ...
