Spatially, in the short-term models, around 90% of KCs contained tumour material at the tumour margin, while only approximately 60% and 30% did between 50 to 500 μm and more than 500 μm away from the tumour margin, respectively (Fig. 2d), and tumour material (tdT) in KCs was colocalized with LAMP1+ phagolysosomes (Fig. 2e). This evidence concerns the gene LAMP1 and neoplasm.
