What is organ-on-a-chip technology?
Organ-on-a-chip is a technology combining cells and tissues grown inside microfluidic chips with the aim of recapitulating physiological processes of human organs. The applications of organ-on-a-chip range from disease modeling and drug testing to personalized medicine and the development of cell and gene therapies. There are a diverse array of organ-on-a-chip devices available and Axion’s innovative platforms can noninvasively monitor cells in microfluidic systems allowing the study of complex physiological processes.

Purpose: To study self-assembly of individual spheroids in a microfluidic chip under perfusion.
HeLa cells cultured in a μ-Slide Spheroid Perfusion (Ibidi) were monitored using the Omni platform.
Result: HeLa cells started to aggregate and self-assemble into spheroids during the first 20 hours post-culturing. Perfusion in a microfluidic device can ensures optimal nutrition during long-term spheroid cultures.
Purpose: To examine chemotactic migration of human neutrophils through a microscopic maze. Neutrophil chemotaxis is a critical immune response to detect and move toward damaged tissue or infections.
Human neutrophils were added to the microfluidic maze containing LTB4 chemoattractant. The cells were imaged using the Lux platform.
Result: The neutrophils migrated through the microscopic channels towards the LTB4 chemoattractant.
Purpose: To demonstrate synaptic connectivity between different neuronal subtypes. Brain-on-a-chip models can shed light on the interaction between different brain regions.
Cortical and hippocampal neurons were cultured in separate chambers of the DuaLink MEA (Netri) and recorded on the Maestro MEA platform over 21 days.
Results: Cultures increased synchronous firing between chambers as new synapses formed over time.
Purpose: To monitor growth and activity in neurites. Understanding the growth and function of neural projections could aid in the development neuroregenerative medicine.
Cortical neurons were cultured in one chamber of the DuaLink MEA (Netri) and recorded on the Maestro MEA platform.
Results: As new neurite projections covered the empty chamber, increasing activity was observed. This activity was synchronous to the activity in the cortical chamber.
