Cytogenetic changes
WebCytogenetics involves testing samples of tissue, blood, or bone marrow in a laboratory to look for changes in chromosomes, including broken, missing, rearranged, or extra chromosomes. Changes in certain chromosomes may be a sign of a genetic disease or condition or some types of cancer. WebTraditionally, routine screening of PSC lines for the identification of genetic changes has been performed mainly by cytogenetic and molecular methods that are capable of detecting numerical and ...
