Treatment of cancer using stem cells youtube

Vaccine-like treatments could one day be used to prevent people from developing cancer, new study has found. Researchers identified and tracked rare immune system cells that could be programmed to keep cancer at bay over a period of many years. For such an approach to work, the memory T-cells would have to be primed by genetic modification to attack the target cancer. But the first step is to single out those cells with the ability to persist for a long time. Prof Bonini’s team studied 10 cancer patients who underwent bone marrow transplants and were infused with T-cells that were tagged so they could be tracked. Small numbers of the cells were still found to be circulating in the patients’ blood streams after 14 years.
The research was described at the annual meeting of the American Association for the Advancement of Science (AAAS) taking place in Washington DC. Researchers at the Memorial Sloan Kettering Cancer Center recently reported that it was possible to repair brain damage caused by radiation therapy for brain cancer by using lab-generated cells derived from human stem cells. Radiation is one of the therapies often used in treating brain cancer patients. However, it can induce significant and irreversible damage to the brain that can lead to deterioration of the quality of life for cancer survivors.
The team developed a new strategy where they could transform human stem cells, in the presence of a cocktail of molecules including growth factors, into cells programmed to repair brain injuries — oligodendrocyte progenitor cells. The lab-generated oligodendrocyte progenitor cells where then implanted in rats that had been previously subjected to brain irradiation, and had therefore suffered de-myelination of neurons and presented cognitive deficits.

Embryonic stem cells have more developmental potential; which means that it would be able to give rise to cells found in all tissues of the body. Therapeutic cloning is a method to produce stem cell lines that were genetic matches for adults and children.
Stem cells are found in limited quantities in every human body, and can be extracted from adult tissue with great effort but without harm.
Altered nuclear transfer makes harvesting stem cells possible without any potential damage to the developing embryo. Tip: To turn text into a link, highlight the text, then click on a page or file from the list above.
Scientists silenced the extra copy of a chromosome that causes Down syndrome in laboratory stem cells, offering the first evidence that it may be possible to correct the genes responsible for the disorder.
While some genetic disorders have been easier to study because a single gene drives them, Down syndrome is more complex, said Robert Nussbaum, chief of genomic medicine at the University of California, San Francisco.
In today’s paper, researchers led by Jeanne Lawrence, a professor of the department of cell and developmental biology at the University of Massachusetts Medical School, used a gene called Xist.

The scientists used skin cells from a Down syndrome patient that had been tricked into reverting into stem cells that, like embryonic ones, can grow into any type of tissue.
Once inserted into the stem cells, scientists switched on Xist using the antibiotic tetracycline, setting off a process that effectively silenced the extra chromosome, Lawrence said.
When the chromosome had been silenced, the cells grew better in the culture, Lawrence said. I'm a postdoc working on the prevention of fibrosis in Crohn's disease, IBD, and intestinal parasite infection.
Hematopoietic tissue houses cells that retain long term and short term regeneration capacities and committed multipotent, oligopotent and unipotent progenitors. Cells can be obtained directly by removal from the hip using a needle and syringe, or from the blood following pre-treatment with cytokines, such as G-CSF (granulocyte colony stimulating factors), that induce cells to be released from the bone marrow compartment.
In patients with various types of cancer and some immune deficiency diseases, the stem cells in the bone marrow malfunction, producing an excessive number of defective or immature blood cells or low blood cell counts. While bone marrow transplants do not provide 100 percent assurance that the disease will not recur, a transplant can increase the likelihood of a cure or at least prolong the period of disease-free survival for many patients.

After radiation therapy, the progenitor cells that would eventually evolve to generate the protective myelin coating surrounding neurons are lost or significantly reduced, and it is currently not possible to restore these cells. This strategy was successfully accomplished with both human embryonic stem cells and induced pluripotent stem cells from the skin. Remarkably, rats treated with these specific human progenitor cells re-acquired their cognitive and motor coordination functions that were lost after exposure to radiation.

The only difference is that instead of removing stem cells, the blastocyst is implanted in a woman. About 4-5 days post fertilization cells are being obtained from the blastocyte; after the cells are being harvested the embryo is ultimately destroyed. About 6,000 babies are born every year with the condition, which is caused by an extra copy of chromosome 21.
The gene creates a regulating piece of RNA that ordinarily quiets the second X chromosome in women.
Then they inserted a copy of Xist into the extra chromosome using technology from Richmond, California-based Sangamo. Other sources for clinical and scientific use include umbilical cord blood, placenta, and mobilized peripheral blood. This protective myelin coating is generated by oligodendrocytes, which are vital for the support, protection, and repair of brain neurons. Jinghua Piao showed that stem cells could be used as a tool to restore destroyed oligodendrocyte progenitor cells.
In terms of safety, the team found that none of the rats developed any kind of inappropriate cell types or brain tumors. Her work has been focused on molecular genetic traits of infectious agents such as viruses and parasites.

In women, the extra RNA makes copies that coat the whole second X chromosome, preventing it from producing proteins.
Stem cells are undifferentiated cells capable of differentiating into different specialized cell types, like the skin, bone, muscle, etc. Always seek the advice of your physician or other qualified health provider with any questions you may have regarding a medical condition. The cells harvested are being cultivated under special laboratory conditions where it can be later used for treating different types of diseases as well as transplantation of vital organs. The scientists wondered if this quieting effect could be used specifically to silence the third copy of chromosome 21.
Never disregard professional medical advice or delay in seeking it because of something you have read on this website. Stem cells can be used to generate an organ or tissue that is a genetic match to the skin cell donor.
