Our flow-based platforms mimic vascular conditions, allowing the study of cellular interactions in dynamic, human-relevant environments.
By combining controlled flow, human cells, real-time imaging, and AI analysis, they enable precise investigation of immune behavior, vascular interactions, and tissue interfaces.
The platform includes two complementary flow systems to cover different levels of biological complexity.

Single-chamber flow system


A single-chamber micro-physiological flow platform.
The blood cells, derived from human blood, either as isolated leukocytes or as whole blood, are perfused through a vessel-like channel using a pump system. The flow rate is adjusted to replicate physiological conditions found in blood vessels.
Dual-chamber flow system


A next-generation dual-chamber platform to study organoids and complex physiological interactions under flow.
Here, a semi-permeable membrane separates the neural tissue compartment from the vascular layer modelling the blood-brain barrier. The platform is designed to be adaptable to a range of 2D tissues and organoid types, enabling the investigation of cell-cell interactions under controlled flow conditions in the vascular chamber which has direct physical contact with the static organoid compartment.

We leverage artificial intelligence (AI) to enhance the analysis of complex cellular behaviors, enabling more accurate and efficient data interpretation. Our AI is applied through proprietary software solutions, developed and continuously refined by our scientists, ensuring accurate and meaningful interpretation of cellular dynamics. Together, these tools represent a shift from manual methods to advanced, label-free AI-driven leukocyte tracking, delivering greater efficiency, consistency and insight.
Precise quantification of leukocytes
Detailed analysis of cell migration, transmigration and locomotion
AI Softwares
Developed by MesenFlow, these software packages were established through deep convolutional neural network algorithm to detect and classify cell transmigration. The algorithm is based on operation blocks that allow the AI to learn patterns it observes within similar cells. High accuracy counts are achieved by extensive data pre-processing, formatting, and post-processing to create a pipeline that integrates well within our current workflow.

Profile of human peripheral blood leukocytes (PBLs) trafficking in human umbilical vein endothelial cells (HUVECs) under flow.
PBLs were flowed over activated HUVECs for 5 minutes (area marked in grey). Captured PBLs were individually tracked, and their positions marked at set intervals. PBLs captured from free flow became rapidly activated by rolling on the luminal surface, changing phase from white to grey (Capture) before transmigrating into the ablumen (Transmigration).
