There are many reasons for the selective absorption of the PS by tumour cells, including the dense vacuolisation of tumour tissue, which increases the surface area for PS uptake [100], the increased permeability of cancer cell membranes and the presence of increased Low Density Lipoproteins (LDL) receptors, which increases PS uptake via the endocytosis of LDL-PS complexes [101]. Here, LDLR is linked to neoplasm.
