  1. Microfluidic perfusion culture for controlling the stem cell microenvironment

    … signaling. Especially in conventional static culture, the content of the cell culture media changes constantly over time as cells interact with and modify their surroundings. This thesis explores the use of microfluidic perfusion as a tool for modulating diffusible cell-cell signaling in mESC …

    … are presently utilized to maintain long-term perfusion culture. However, this increases the risk of introducing external contaminants into the cell culture and the analyzed analytes. Sensors used in in-line probe-based approaches must withstand harsh clean-in-place and sterilization-in-place …

  4. The Biological Impact of High Throughput Continuous Bioprocessing

    Micro scale, high throughput perfusion technology is under-developed and not widely utilised in academic or industrial settings for the development of CHO based mAb bioprocesses. Work within this thesis highlights the design and characterisation of a sedimentation method of cell retention and its …
