Abstract

Lung cancer is one of the most incident neoplasms in the world, representing the main cause of mortality for cancer. Many epidemiologic studies have suggested that physical activity may reduce the risk of lung cancer, other works evaluate the effectiveness of the use of the physical activity in the suppression, remission and reduction of the recurrence of tumors. The aim of this study was to evaluate the effects of aerobic and anaerobic physical activity in the development and the progression of lung cancer. Lung tumors were induced with a dose of 3mg of urethane/kg, in 67 male Balb – C type mice, divided in three groups: group 1_24 mice treated with urethane and without physical activity; group 2_25 mice with urethane and subjected to aerobic swimming free exercise; group 3_18 mice with urethane, subjected to anaerobic swimming exercise with gradual loading 5-20% of body weight. All the animals were sacrificed after 20 weeks, and lung lesions were analyzed. The median number of lesions (nodules and hyperplasia) was 3.0 for group 1, 2.0 for group 2 and 1.5-3 (p=0.052). When comparing only the presence or absence of lesion, there was a decrease in the number of lesions in group 3 as compared with group 1 (p=0.03) but not in relation to group 2. There were no metastases or other changes in other organs. The anaerobic physical activity, but not aerobic, diminishes the incidence of experimental lung tumors.

Stem cell

From Wikipedia, the free encyclopediaJump to navigationJump to searchHuman embryonic stem cells
A: Cell colonies that are not yet differentiated.
B: Nerve cell

Stem cells are cells of the body (somatic cells) which can divide and become differentiated.[1]

When an organism grows, stem cells specialize, and take specific functions. For instance, mature tissues like skinmusclebloodbonelivernerves, all have different types of cells. Because stem cells are not yet differentiated, they can change to become some kind of specialized cells. Organisms also use stem cells to replace damaged cells.

Stem cells are found in most, if not all, plants and animals. They divide and differentiate into a range of cell types.Research in the stem cell field grew out of findings in the 1960s.[2][3]

The two broad types of mammalian stem cells are embryonic stem cells, and adult stem cells, which are found in adult tissues. In a developing embryo, stem cells can differentiate into all of the specialised embryonic tissues. In adult organisms, stem cells act as a repair system for the body, replenishing specialized cells, but also maintain the normal turnover of bloodskin, and intestinal tissues.

Stem cells can be grown in tissue culture. In culture, they can be transformed into specialised cells, such as those of muscles or nerves. Highly plastic adult stem cells can be taken from a variety of sources, including umbilical cord blood and bone marrow. They are now used in medical therapies, and researchers expect that stem cells will be used in many future therapies.[4]

Embryonic stem cells[change | change source]

Human embryonic stem cell colony

Embryonic stem cells (ES cells) are stem cells taken from the inner cell mass of the early stage embryo called a blastocyst. Human embryos reach the blastocyst stage 4-5 days after fertilization. At that time, they are made up of between 50 and 150 cells.

The stem cells’ state, and what the daughter cells turn into, is influenced by signals from other cells in the embryo.

Adult stem cells[change | change source]

Adult stem cells exist throughout body after embryonic development has completed. They are found inside different types of tissue and remain in a non-dividing state until disease or tissue injury. They have changed permanently into specialised cells and have lost the ability to divide and specialise further. An advantage of adult stem cells is that it provides a lesser probability of rejection. A disadvantage would be that there is a limited availability to get them.

Plant stem cells[change | change source]

Plant stem cells are unspecialised, and can develop into any type of plant cell. They become specialised into cells of roots, leaves or flowers. The stem cells are found in meristem, at root and stem apices. They make it possible for growth to continue.

Cloning plants[change | change source]

These are plants which have been grown from cuttings (therefore the same plant). They are dipped in hormone rooting powder to develop bigger root systems. They turn into tissues (eg. xylem and phloem) and organs (eg. roots, leaves and flowers), therefore becoming a completely new plant.

Cloning plants is a cheap way of producing a new plant.

Stem cells in medicine[change | change source]

Some cancers may be treated by stem cells. Leukemia, a cancer of white blood cells (WBC) is an example.

There are two stages to this process:

  • Chemotherapy and radiotherapy to kill cancerous white blood cells and stop the production of more. However, this may leave the patient with a severely compromised immune system with a risk of infection.
  • A transplant of bone marrow containing healthy stem cells (to produce normal WBC).
