biopsy and histopathological evaluation of the tissue and blood and bone marrow tests. In biopsy, a piece of the suspected tissue is cut into thin sections and stained with hematoxylin and eosin (H&E) and examined under microscope (histopathological studies) to see rapidly dividingcancer cellsby ...
Hexaminolevulinate (HAL) induced Protoporphyrin IX (PpIX) fluorescence is commonly used to differentiate cancer cells from normal cells in vivo, as for instance in blue light cystoscopy for bladder cancer diagnosis. A detailed approach is here provided to use this diagnostic principle ex vivo in a...
As abovementioned, a liquid biopsy does not only rely on the evaluation of CTCs. The secretion of proteins from tumor cells has been investigated through label-free quantitative proteomics approaches on plasma samples. Tumoral secretomes are highly abundant in plasma since cancer cells are much more...
Suhanya Duraiswamy, in Bioprinting, 2023 2.2 Co-culture or two cell-type cancer models Co-culture or chimera models are characterized by the integration of two distinct cell types. These models are typically created by combining non-tumorigenic cells with cancer cells, enhancing complexity for ...
Colorectal cancer, disease characterized by uncontrolled growth of cells within the large intestine (colon) or rectum. Colon cancer (or bowel cancer) and rectal cancer are sometimes referred to separately. Colorectal cancer develops slowly but can spread
Nowadays, liquid biopsy has received enormous attention as it has emerged as a minimally invasive approach for detecting cancer at an early stage [12]. Liquid biopsies mainly include cell-free DNA (cfDNA), circulating tumor cells (CTCs) and exosomes. In addition to the above-mentioned, sputum,...
Currently, circulating tumor cells (CTCs), circulating tumor DNA (ctDNA) and exosomes have become the three main branches of liquid biopsy [15,16]. Compared with CTCs and ctDNA, exosomes have shown greater advantages in liquid biopsy. First, the presence of large amounts of exosomes (~ ...
Tumour cells are able to shed macromolecules into the bloodstream, both from primary and metastatic sites. Assays capable of sampling, isolating and testing analytes from a biological fluid are referred to as a liquid biopsy. Liquid biopsy is minimally invasive and easily repeatable. Various biologic...
Liquid biopsy is less invasive than tumour biopsy, but, to date, no liquid biopsy biomarkers have been clinically approved for RCC diagnosis. Circulating tumour cells (CTCs) seem less suitable than extracellular vesicles (EVs) for cancer detection in SRMs, owing to low epithelial cell adhesion mol...
