Hypothesis and development of tumor pre-metastatic nich / 国际外科学杂志

Tumor invasion and metastasis are regarded as main reasons for the failure of therpy and the reason of patients death.The mechnism of tumor metastasis is still uncertain.The pre-metastatic niche hypothesis provides us with new ideas to discover the mechnism.Numerous materials are involved in the formation of the pre-metastatic niche according to this hypothesis,including bone marrow-derived cells,microvesicles,exosomes,CD44,and so on.A further research on this hypothesis helps to deeply understand the nature of metastasis and leads clinical doctors to explore novel targets for clinical diagnoses and therapies.
