BLASTEMA THEORYThe theory was developed in 1838 by Johannes Murell, which demonstrates that a cancer is made up of a cells and not lymph. Cancer cells did not arise from normal cells; it arose from budding of elements blastema between normal tissues.
BLASTEMABlastema is a mass of undifferentiated cells which is capable of growth differentiation. It also refers to any zone of embryonic tissue that is still differentiating and growing into a particular organ. The term is usually applied to the tissue that develops into kidney and gonads.
DIFFERENTIATIONIn Embryology, differentiation refers to the process in embryonic development during which unspecialized cells or tissues become specialized for particular functions. In the concept of oncology, differentiation is the degree of similarity of tumour cells to the structure of the organ from which the tumour arose. Tumours are classified as well, moderately, or poorly differentiated; well-differentiated tumours appear similar to the cells of the organ in which they arose; poorly differentiated tumours do not. Such classification is often of prognostic significance and determines the grade of the tumour. Well differentiated tumours are low grade, poorly differentiated tumours are high grade.
CONCLUSION:Cancer is made up of cells and not lymphatic fluid. This theory emphasizes the beginning or onset of cancer in correlation of concept of cell development.
