Cancer cells are cells that divide continually, forming solid tumors or flooding the blood or lymph with abnormal cells. Cell division is a normal process used by the body for growth and repair. A parent cell divides to form two daughter cells, and these daughter cells are used to build new tissue or to replace cells that have died because of ...
The word leukemia, which means 'white blood', is derived from the characteristic high white blood cell count that presents in most affected people before treatment. The high number of white blood cells is apparent when a blood sample is viewed under a microscope, with the extra white blood cells frequently being immature or dysfunctional. The ...
Live-cell imaging is the study of living cells using time-lapse microscopy. It is used by scientists to obtain a better understanding of biological function through the study of cellular dynamics. [1] Live-cell imaging was pioneered in the first decade of the 21st century.
A new microscope developed by researchers at the University of Washington can help surgeons figure out whether tissue samples still contain cancerous cells.
Based on the structure of a micronucleus, or the function of a cell, it seems to provide support in the central apparatus within the cell. Micronuclei are under investigation and research regarding whether or not they can be used to predict future cancer risks. It seems that they are easy to analyze compared to chromosome aberrations.
The process involves the extraction of sample cells or tissues for examination to determine the presence or extent of a disease. The tissue is then fixed, dehydrated, embedded, sectioned, stained and mounted [1] before it is generally examined under a microscope by a pathologist; it may also be analyzed chemically.
Cancer is a group of diseases that involve abnormal increases in the number of cells, with the potential to invade or spread to other parts of the body. [1] Not all tumors or lumps are cancerous; benign tumors are not classified as being cancer because they do not spread to other parts of the body. [ 1 ]
An illustration depicting primary tumor (in the form of tumor microenvironment) and the circulating tumor cells. A circulating tumor cell (CTC) is a cancer cell from a primary tumor that has shed into the blood of the circulatory system, or the lymph of the lymphatic system. [1]
