- cancer setting marrow regeneration contributes
Regeneration is in biology, regrowth of damaged or destroyed tissue or body part. Cancer is a term for diseases in which abnormal cells divide without control and can invade nearby tissues. Cancer cells can also spread to other parts of the body through the blood and lymph systems. There are several main types of cancer. Carcinoma is a cancer that begins in the skin or in tissues that line or cover internal organs. Sarcoma is a cancer that begins in bone, cartilage, fat, muscle, blood vessels, or other connective or supportive tissue. Leukemia is a cancer that starts in blood-forming tissue such as the bone marrow, and causes large numbers of abnormal blood cells to be produced and enter the blood. Lymphoma and multiple myeloma are cancers that begin in the cells of the immune system. Central nervous system cancers are cancers that begin in the tissues of the brain and spinal cord. Also called malignancy.
Preview- It`s been discovered that, some patients who undergo bone marrow transplant later develop secondary cancers because of the high doses of radiation and chemotherapy they receive to prepare them for the procedure, said Mariusz Ratajczak, M.D., Ph.D., director of the Stem Cell Developmental Biology Program at the University of Louisville James Graham Brown Cancer Center and a member of the journal`s editorial board. Transplanted cells which are derived initially from the bone marrow can include a population of stem cells which can on one hand do nice things and contribute to regeneration, and conversely if something goes wrong, these cells can also contribute to cancer development, of course in very rare cases, Ratajczak said. This study has very nicely shown that that possibility exists, and it actually describes a new, novel mechanism. Bone marrow is the soft, sponge-like tissue in the center of most bones. It produces white blood cells, red blood cells, and platelets. Cell is the individual unit that makes up the tissues of the body. All living things are made up of one or more cells. Chemotherapy, treatment with drugs that kill cancer cells. Radiation, energy released in the form of particle or electromagnetic waves. Common sources of radiation include radon gas, cosmic rays from outer space, medical x-rays, and energy given off by a radioisotope (unstable form of a chemical element that releases radiation as it breaks down and becomes more stable). Stem cell is a cell from which other types of cells develop. For example, blood cells develop from blood-forming stem cells.
- One can recognize, bone marrow stem cells attracted to the site of a malignant growth frequently take on the outward appearance of the cancerous cells around them, University of Florida scientists report in a paper would be reported in the recent issue of Stem Cells. But whether that enables them to fuel cancer`s ability to develop and then spread, as some researchers suspect, is not entirely clear. Malignant, cancerous. Malignant cells can invade and destroy nearby tissue and spread to other parts of the body.
- One can assume that, a form of specialized muscle cells surrounding capillaries, called a pericyte, has been discovered to play a role in initiating angiogenesis, or blood vessel growth, according to researchers at Tufts University School of Medicine (TUSM) and the Massachusetts Institute of Technology (MIT). The study, published in Journal of Physics: Condensed Matter, suggests that these cells use mechanical forces to initiate sprouting of new blood vessels, a new discovery in the angiogenesis field. Previously, scientists have focused on the chemical signals that initiate angiogenesis and have developed drugs, known as angiogenesis inhibitors, to impede these signals in cancerous tumors and in blinding diseases, such as age-related macular degeneration. Chemical is a substance made up of elements, such as hydrogen or sodium. Medicine, refers to the practices and procedures used for the prevention, treatment, or relief of symptoms of a diseases or abnormal conditions. This term may also refer to a legal drug used for the same purpose. Blood is a tissue with red blood cells, white blood cells, platelets, and other substances suspended in fluid called plasma. Blood takes oxygen and nutrients to the tissues, and carries away wastes. Angiogenesis, blood vessel formation. Tumor angiogenesis is the growth of new blood vessels that tumors need to grow. This process is caused by the release of chemicals by the tumor and by host cells near the tumor. Blood vessel is a tube through which the blood circulates in the body. Blood vessels include a network of arteries, arterioles, capillaries, venules, and veins. Age-related macular degeneration is a condition in which there is a slow breakdown of cells in the center of the retina (the light-sensitive layers of nerve tissue at the back of the eye). This blocks vision in the center of the eye and can cause problems with activities such as reading and driving. Age-related macular degeneration is most often seen in people who are over the age of 50. Also called AMD, ARMD, and macular degeneration. Macular degeneration is a condition in which there is a slow breakdown of cells in the center of the retina (the light-sensitive layers of nerve tissue at the back of the eye). This blocks vision in the center of the eye and can cause problems with activities such as reading and driving. Macular degeneration is most often seen in people who are over the age of 50. Also called age-related macular degeneration, AMD, and ARMD.
