Results

A major achievement of the TiMaScan project is the development of an antibody panel for detection of different subsets of monocytes by flow cytometry. This antibody panel was used to show that in humans, the numbers of different monocyte subsets, including classical, intermediate and non-classical monocytes, differ depending on age and tissue (Figure 1; Damasceno et al., 2019).

Furthermore, by monitoring different subsets of monocytes in peripheral blood following controlled tissue damage (total hip arthroplasty), we showed that changes in numbers of classical monocytes, which followed the same temporal pattern as total monocytes, are different from the changes in numbers of non-classical monocytes (Figure 2; Van den Bossche et al., 2018).

A patent that covers the detection of monocyte subsets to monitor disruption of tissue homeostasis was filed and granted, and has been licensed to Cytognos.
