Contreras-Zarate MJ et al. developed and characterized novel heterogeneous and clinically relevant human brain metastasis breast cancer PDXs (BM-PDXs) to study mechanisms of brain metastatic colonization, with the added benefit of a slower progression rate that makes them suitable for preclinical testing of drugs in therapeutic settings. [20]
The cancer stem cell model asserts that within a population of tumour cells, there is only a small subset of cells that are tumourigenic (able to form tumours). These cells are termed cancer stem cells (CSCs), and are marked by the ability to both self-renew and differentiate into non-tumourigenic progeny. The CSC model posits that the ...
CNS metastasis is the spread and proliferation of cancer cells from their original tumour to form secondary tumours in portions of the central nervous system. [ 1 ] The process of tumour cells invading distant tissue is complex and obscure, but modern technology has permitted an enhanced detection of metastasis .
Breast cancer metastatic mouse models are experimental approaches in which mice are genetically manipulated to develop a mammary tumor leading to distant focal lesions of mammary epithelium created by metastasis. Mammary cancers in mice can be caused by genetic mutations that have been identified in human cancer. This means models can be ...
Common sites of metastasis for breast cancer. Metastatic breast cancer, also referred to as metastases, advanced breast cancer, secondary tumors, secondaries or stage IV breast cancer, is a stage of breast cancer where the breast cancer cells have spread to distant sites beyond the axillary lymph nodes. There is no cure for metastatic breast ...
Metastasis is the most common cause of brain cancer, as primary tumors that originate in the brain are less common. [4] The most common sites of primary cancer which metastasize to the brain are lung, breast, colon, kidney, and skin cancer. Brain metastases can occur months or even years after the original or primary cancer is treated.
The organ tropism of patient-derived CTC has been investigated in a mouse model. [88] CTCs isolated from breast cancer patients and expanded in vitro showed they could generate bone, lung, ovary and brain metastases in mice, partially reflecting the secondary lesions as found in the corresponding patients. Remarkably, one CTC line—isolated ...
