Beschreibung

Hematopoietic stem and progenitor cells (HSPCs) are responsible for the continuous formation of blood and immune cells. Their metabolism changes in response to environmental and disease-related signals and may reveal new therapeutic targets.

This Master’s thesis is part of a PhD research project developing a human-relevant microfluidic in vitro platform for HSPC culture. The system combines a lab-on-a-chip device, three-dimensional hydrogel-based cell culture, controlled perfusion, inflammatory stimulation, and microscale nuclear magnetic resonance spectroscopy (µNMR).

The long-term objective of the platform is to investigate metabolic responses during disease, identify potential therapeutic targets, and support the testing of new drugs in a controlled human in vitro model.

The goal of the Master’s thesis is to establish and optimize the culture of HSPCs within the microfluidic chip and to characterize the effects of perfusion and inflammatory stimulation on cell viability, cellular state, and metabolism.

A particular focus will be placed on improving the on-chip culture conditions through engineering-based optimization of fluid flow, nutrient transport, and hydrogel properties. The optimized platform will subsequently be used to perform an LPS stimulation experiment and analyze extracellular metabolic changes using µNMR spectroscopy.

Main tasks:
- Establishment of hydrogel matrix in the microfluidic chip
- Optimization of perfusion conditions
- Investigation of flow, shear stress, nutrient transport, and metabolite removal
- Computational simulation and flow optimization
- Characterization of the hydrogel matrix
- Establishment and performance of LPS treatment experiments
- µNMR measurements of cell culture samples
- Processing and analysis of NMR spectra
- Correlation of metabolic changes with cellular responses

The exact focus can be adapted to the student’s background and interests, with a stronger emphasis on experimental cell culture, microfluidic engineering, simulation, biomaterials, or metabolic analysis.
