CD44 and neoplasm: The transcriptomic profiling of human breast tumours and mouse stroma cells revealed that RG7356 induced a significant immune-stimulatory effect by binding to CD44+ tumour cells, resulting in the secretion of chemoattractants that are essential for immune cell recruitment (i.e., macrophages) to the tumour site, finally leading to antibody-dependent cellular phagocytosis (ADCP) of the cancerous cells by macrophages [208].
