Which type of tissue would have a higher mitotic index, normal tissue or cancerous tissue? Explain. niamh_somers https://padlet.com/niamh_somers/6qa2ah3674fo/wish/134025644 2016-10-29 07:50:53 UTC https://padlet.com/niamh_somers/6qa2ah3674fo/wish/134025644 Different types of normal tissues in the human body have different mitotic indices. From the following list, which normal tissues would you expect to have the highest mitotic index: muscle, skin, kidney, or lung? Explain your answer. niamh_somers https://padlet.com/niamh_somers/6qa2ah3674fo/wish/134025655 2016-10-29 07:51:15 UTC https://padlet.com/niamh_somers/6qa2ah3674fo/wish/134025655 Abdul https://padlet.com/niamh_somers/6qa2ah3674fo/wish/134067591 Different organs have different cell division rates, however cancerous organs will always have a higher division rate]]> 2016-10-30 06:52:05 UTC https://padlet.com/niamh_somers/6qa2ah3674fo/wish/134067591 ani, alex and moaz https://padlet.com/niamh_somers/6qa2ah3674fo/wish/134067597 The cancerous lung cells have more cells dividing, whereas cancerous stomach cells have less cells dividing]]> 2016-10-30 06:52:25 UTC https://padlet.com/niamh_somers/6qa2ah3674fo/wish/134067597 Saoud https://padlet.com/niamh_somers/6qa2ah3674fo/wish/134067614
No matter how high the ratio for healthy cells would be, the cancerous ratio would always be higher. There are different acceptable ratios for different types of cells so a certain healthy ratio should be used as reference to deduce if the ratio shows a cancerous cell or not.]]> 2016-10-30 06:53:11 UTC https://padlet.com/niamh_somers/6qa2ah3674fo/wish/134067614 Maira & Eliana https://padlet.com/niamh_somers/6qa2ah3674fo/wish/134067618 Cancer cells have a higher ratio of cell division than normal cells.

However, a high ratio of cells undergoing mitosis does not always mean the cells are cancerous, as some parts of the body would require cells to undergo more rounds of mitosis than others depending on that part of the body's function. An example would be skin cells that have to regenerate faster when compared to pancreatic cells.

The main thing that distinguishes cancer cells from normal cells is uncontrolled growth. Healthy cells will reproduce only when the body needs them to do so. Cancer cells have escaped from the body's normal control systems and continue to reproduce over and over, populating an area of the body with too many cells, which are often of the wrong type for the location they are in. Because of their rapid rate of reproduction, many cancer cells do not mature and differentiate properly, so they are essentially useless to the body.


In normal cells, cells reproduction is often density dependent. This means that crowding suppresses cell division. Cancer cells are rarely affected by density, retaining their ability to divide even under crowded conditions.
