Environmental cell biology? Never heard of it? That's not bad at all. There are only a handful of environmental cell biology research groups in the world. Environmental cell biology is a multidisciplinary field that combines medicine, biology, chemistry, physics and ecology to better understand the interactions between cells and their environment. The most important aspects here are: cellular reactions to environmental factors, cell communication and the interaction between environmental influences and cellular health/disease. 

Environmental...

In addition to genetic information (genome, epigenome), the environment is the second important factor on which the function and developmental fate of a cell depends. In the Environmental Cell Biology group, we investigate cellular effects that are triggered in response to changing environmental conditions. In multicellular organisms, such as humans, we distinguish between external influencing factors outside (macro-environment; chemical: pollutants; physical: climatic changes, radiation; biological: pathogens), and internal influencing factors within the human body (micro-environment). While the influence of the macro-environment is usually conceivable, the cell micro-environment can also change, for example triggered by diseases or other physiological reactions of the body (stress, endocrine and (neuro)immunological reactions, microbiome).

...Cell Biology

Every biological process in the human body, no matter how complex, begins with the individual cell, which is why basic research in cell biology is the key to understanding pathogenesis in vivo, but also to developing suitable disease models in vitro. In our research group, we use technology from the space sciences not only to investigate the effects of weightlessness (microgravity) on human cells, but also to study mechanodynamic disease models (e.g. to investigate cancer metastasis), to optimize in vitro cell cultures and to understand and harness developmental biological processes in the field of self-organizing tissue engineering. Understanding how and why cells react to changing environmental factors could also open the door to new and improved treatments for diseases.

 

What we are working on:
  • Novel therapeutic approaches against cancer (microgravity, natural substances, photodynamic therapy, hyperthermia, ...)
  • Strategies against multi-resistant super germs
  • Cell technology (in vitro models, replacement for animal experiments)
What we want to understand:
  • How cells perceive their environment and how they react to changes in environmental factors
  • Cellular and molecular processes in diseases (e.g. metastasis)
  • Cell biology under extreme conditions (space medicine/biology)

Monocytes

  • Only proliferating, leukemic monocytes respond to the mechanical influences of the RPM (Marchal et al., 2025)

Spheroids: adhesion and anti-adhesion

  • Not all human cells form spheroids when cultured on the RPM. We demonstrated that the balance of adhesion proteins, anti-adhesion proteins and cell-cell junctions determines the formation of spheroids on the RPM (Melnik et al., 2023)

Effects of regolith dust inhalation

Using a physiological in vitro airway model, we investigate the effects of lunar and Martian dust particles on our airways.

Metastasis in a cell culture flask

Formation of tumor spheroids

  • RPM-induced formation of tumor spheroids is a two-step process: detachment of adherent cells by shear forces, followed by aggregation of the detached cells by preventing their sedimentation (Cortés-Sánchez et al., 2023)

CurCUMA project

We are investigating the molecular mechanism of action of curcumin variants using a metastasis model with breast cancer cells.

We could demonstrate that only proliferating, leukemic monocytes respond to RPM with a two-step response. Our article on this topic was published today in Scientific Reports.

28.10.2025

After five years of involvement in the Topic Advisory Panel and recently as a member of the Section Board, Marcus Krüger has been appointed Section Editor-in-Chief (Cancer Biology) for the journal Biology.

10.10.2025

José Luis Cortés Sánchez presented one of our studies on breast cancer as a poster at the 3rd Young Scientist Cancer Congress of the Charité Comprehensive Cancer Center: Molecular Phenotypes of Triple-Negative Breast Cancer Cell Lines in Simulated Microgravity Platforms
