“Cytoskeleton Remodeling in Mesenchymal Cell Migration”

Your project:

Mesenchymal cell migration is characterized by the polarization of the cell body with the formation of membrane protrusions, such as lamellipodia and filopodia, the formation of focalized cell-matrix interaction followed by the retraction of cell rear by active cellular contraction.

It has been long observed that cells can assume different body orientation and shape during mesenchymal-type migration having either a highly polarized shape (fibroblast and neutrophils) or more round/oval-like shape (keratinocytes). From a theoretical point of view, it has been proposed that this is due to the regulation of the balance between pushing and pulling cytoskeleton elements.

This project aims to experimentally demonstrate the validity of the model with the investigation of the contribution of microtubules, actin fibers and intermediate filaments in regulating cell shape. The project will be in close collaboration with the Institute for Theoretical Soft Matter and Biophysics headed by Prof. Gompper at Forschungszentrum Jülich.

We are currently seeking a highly motivated student (f/m) for master thesis project on

“Mechanobiological Characterization of Retinal Pigment Epithelium Collectives”

Your project:

Epithelia structure and functions are not defined by biochemical processes alone but are also highly dependent on their physical characteristics. These have been shown to be emerging proprieties of cell collectives, not predictable from single cell biomechanics. The ECM underlying epithelia is a pivotal player in both signaling of biochemical information to the cells and in controlling mechanical properties.

Retinal pigment epithelium (RPE) is localized at the base of the retinal neuroepithelium and it is critical for its metabolic support and function as light detector. As in all epithelia, RPE cells tightly adhere to the underlying basement membrane (BM), which is the proximal part of the thicker ECM layer called Bruch’s membrane (BrM). The planned project combines hydrogel systems to mimic BrM interactions with the RPE and investigation of how this affects the cell monolayer mechanics. Mechanobiology techniques such as traction force microscopy and monolayer stress microscopy will be combined with hydrogels surface nanopatterning techniques to systematically understand BrM contribution of RPE mechanics.

30% of all pregnancies are lost during the early implantation phase. To increase the success rates of assisted reproductive technologies, a better understanding of the cellular mechanisms of this initial pregnancy phase is required. The project will focus on mechanical aspects of embryo implantation and the interaction between maternal and embryonic epithelia - i.e. the invading trophoblast and the barrier-forming uterine epithelium - via cell-cell contacts and their hormonal regulation

Job Description:

The successful candidate will

  • perform co-culture experiments with endometrial and trophoblast cell lines as well as with primary cells in an in vitro system for the investigation of endometrial receptivity
  • assess co-cultures by means of confocal and traction force microscopy
  • analyze mechanical cues of trophoblast-endometrial interaction.

Qualifications:

We are looking for a candidate with expertise in

  • histology
  • microscopical techniques
  • image analysis
  • cell culture methods

and with a background in cell biology and / or biophysics.


It is expected that the successful candidate is highly motivated to independently pursue the project as part of a PhD thesis.

Keratin intermediate filaments are major constituents of the epithelial cytoskeleton. Their organizing function of cellular space is important for diverse epithelial functions requiring a high degree of keratin network plasticity. We have recently proposed that a continuous cycle of keratin filament assembly and disassembly facilitates rapid and precise adaptation to the different functional requirements.

The successful candidate will (i) further refine methods and tools for monitoring and manipulating the keratin cycle and its modulators, (ii) focus on identifying and characterizing the molecular motors involved in keratin movement and tension generation within the keratin network, and (iii) examine modulators of the keratin cycle that are identified in genetic screens.

We are looking for a candidate with experience in molecular biology, microscopical techniques and image analysis. The candidate should have a strong background in cell biology. It is expected that the successful candidate is highly motivated to independently pursue the DFG-funded project as a basis for a PhD thesis.

Arrhythmogenic cardiomyopathy (AC) is an inherited heart disease for which no pathomechanism-based therapy exists. AC may lead to sudden cardiac death and chronic heart failure. The desmoglein 2 gene (DSG2) is one of the most frequently mutated genes in AC. DSG2 codes for a calcium dependent transmebrane prtoein that localizes to desmosomal cell-cell adhesions. In the heart, desmoglein 2 proteins (Dsg2) are part of a complex electromechanic coupling structure known as the intercalated disc. Even though DSG2 point mutations were identified in patient pedigrees and have been shown to give rise to an AC-like phenotype in mice, only little is known about the compromised properties of mutated Dsg2.

The successful PhD candidate will establish and refine biochemical and microscopical methods to investigate the biosynthesis, transport and degradation of mutated Dsg2. Functional characterization of the mutated proteins will be performed in cell culture systems and will be validated in existing AC model mice.

We are looking for a candidate with experience in molecular biology, microscopical techniques and protein trafficking. The candidate should have a strong background in cell biology. It is expected that the successful candidate is highly motivated to independently pursue the project as part of a PhD thesis.
