Present: Kristina, Erik, Claudia, Tiril, Thomas and Dag

Plan for spring 2022

Current state of project

  • We have some microfluidic chip designs we can use although none are perfect (see examples below)
  • Protocol for fibronectin coating is established
  • Filling with cells works and cells do adhere.
  • Problems with air bubbles.
  • Finite lifetime of cells. Probably because they lack oxygen and correct CO2 level.

Goal for semester

Make a device that fulfills the following

  • Controls CO2 level
    • CO2 input can be quickly changed
    • CO2 concentration is measured
    • feedback from measurement to CO2 input
  • Cells adhere
  • Cells stay alive and divide until they are confluent
  • Splitting: partial cell release by trypsination and increased flow rate
  • Cells continue to adhere and divide after splitting
  • Possibly perform an additional experimentlike
    • migration assay by entering SDF-1/CXCL12 into a side channel
    • Ca2+ activation by flow, PBS and other changes
