Immune Cell Tumor Infiltration
With the recent development of spatial analysis algorithms, it is now possible to further quantify immune cell relationships in terms of cell infiltrations at tumor/stroma margins. Concentric rings placed inside the Tumor-Stroma border at pre-determined distances, allow the quantification of immune cells within defined bands inside a tumor. This approach can help confirm the mechanism of action of therapies that are designed to increase the infiltration of immune cells into tumor from surrounding tissue.

Once we receive your slides or images for evaluation, we develop a customised algorithm to address the specific question of interest. For example, to evaluate therapeutic effect on immune cell tumor infiltration from the stroma we first automatically define tumor and stroma regions of interest (ROI) across the whole tissue section. IHC stained immune cells are then quantified within each ROI before application of proximity regions at the tumor/stroma border to specifically quantify those cells infiltrating into the tumor. Example analysis and data is shown in the images to the right. We analyse each section in a consistent, detailed way to generate data which is fully representative of the staining and cellular distribution present in your tissue samples.
