Cell Survival Sample Clauses

Cell Survival. A cell is said to have retained its reproductive integrity if it is capable of sustained proliferation, that is, if it can grow into a macroscopic colony of 60 cells or more. A survivor that has retained its reproductive integrity is said to be clonogenic. Some cells also die by apoptosis without attempted division. For differentiated cells that do not proliferate, such as nerve muscle or secretory cells, huge doses of radiation are needed to cause them to be unable to function. Go to your Workbook and answer questions 3 – 7 to record your understanding of this section Key Points:   Most body cells reproduce through division and form 2 cells.  Red blood cells do not have a nucleus and can not divide but are manufactured in the bone marrow.  Cells ‘die’ only when they attempt to divide.  Radiation damage to cells is more extensive if it occurs during cell division.  As cell division is more rapid in young children and unborn than in adults so they are considered more at risk from effects of radiation.  Cancerous tumours have rapidly dividing cells and are more likely to be damaged by radiation than normal tissue.  Direct damage causes direct ionization in the molecule  Indirect damage occurs as a result of formation of ‘free radicals’ within the cell.  Some free radicals are formed when water within a cell is ionized.  Free radicals can attack and alter DNA which can lead to cancer.  Chronic exposure: exposure due to low radiation doses over a long period of time - high chance of cell recovery or repair  Acute exposure: exposure to high a radiation dose over a short period of time - cells have less time to recover and lower probability of cell repair  Mechanism of cell repair is an important concept for radiation therapy.
