A Research Study On Stem Cell Therapy

With the hopes of curing the patient’s afflictions, these newly grown cells would then be transplanted into the patient. With this approach come major problems such as the formation of tumours, which is caused by the distinguishing trait of stem cells. Because stem cells are able to divide for an unlimited amount of time, it has been found that the cells will not know when to stop dividing and they will continue to divide even after being transplanted into the patient (Herold 48). This form of treatment is counterproductive, as uncontrollable cell division will produce tumours and potentially cause cancer, which is one of the ailments that stem cell research promises to cure.

Many scientists believe that embryonic stem cell (ESC) research is the key to curing diseases such as cancer and HIV. Stem cells are so important to biomedical research because they are primitive cells that are capable of replicating indefinitely producing a multitude of different types of cells. This means that one of these pre-determined cells has to potential of becoming any range of over two hundred tissues with epithelial cells to blood and

Stem cells may be model for benign ACTH producing adenomas like seen in several cancers.

The duo's research, supported by the National Institutes of Health and Cancer Prevention and Research Institute of Texas, further supports an existing theory that cancer is a stem cell disease. Multiple studies have shown that even within the same lesion, not all cancer cells are the same. Researchers also often find cancerous stem cells within a lesion, and many believe these cells are the key to preventing the initiation and relapse of cancer.

The notch pathway is a new avenue in battling melanoma which holds promise in preventing chemoresistance. The notch pathway is an evolutionarily conserved embryonic cell pathway important for cell fate and differentiation.32 Studies have suggested that dysregulated notch signaling can prolong and confer life to cancer stem cells, which are thought to be important in tumor chemoresistance.33 Other studies have shown that notch activation promotes melanoma tumorigenesis and progression.32 Thus, therapeutic benefit of targeting notch signaling includes preventing tumor angiogenesis, cancer stem cell depletion, and cell death.34 The notch receptor family consists of four transmembrane receptors (Notch 1-4).35 Recent research on melanoma cells

Cancer is one of the top life-threatening diseases, accounting for an estimated one in four human deaths in all age groups. Cancer remains one of the leading causes of mortality and morbidity throughout the world. Despite improved treatment models, many tumors remain unresponsive to traditional therapy. The major obstacle to the development of effective cancer therapy is believed to be the absence of sufficient specificity. Since the discovery of the tumor-oriented homing capacity of stem cells (SCs), the application of specific anticancer gene-engineered SCs has held great potential for cancer therapies.

Stem cell therapy, also known as regenerative medication, has been an increasingly utilized therapy in recent years. The cells added to the body interact with the surrounding body, making the regenerative process available to begin the healing process of the cells at the site (R. (2014)). These therapies are used to heal common sport injuries such as a knee injury, diseases, arthritis, and many other crippling effects that may occur in the human body (R. (2014)). Many of the stem cells that are used from the therapies can come from bone marrow, fat,and blood from the patient or even cells from more controversial areas such human embryos. Stem cell therapy has shown a lot of promising effects, not only outshining the effects of prescription medicine given out to patients from doctors, but it has also shown that the therapy has long term effects than a steroid would have had.

For years individuals have fought through the deadly disease we all know to be cancer. Malignant tumors, are group of diseases involving abnormal cell growth with the potential to invade and/or spread to other parts of the human body. There are over 100 kinds of cancers and diseases in this world. Scientists has enlightened the world with a new discovery of treatment for certain diseases by using stem cells. Embryonic stem cells can become all cell types of the body because they are pluripotent. Embryonic stem cells are known to be pluripotent stem cells, which derived from the inner cell mass of a blastocyst, an early stage preimplantation embryo. Human embryos reaches to the blastocyst stage. The Blastocyst stage is known to be 4 to 5 days post fertilization, which can consist of 50 to150 cells or more. Which can make a difference in the life of many based off of 150 cells. Adult stem cells are thought to be limited to differentiating into different kinds of cell types of their tissue of origin. Stems cells are not known to cure all diseases directly. They can help you with your recovery, also

A major goal of cardiac stem cell therapy is to transplant enough cells into the myocardium at the site of injury or infarction to maximize restoration of function. Several different approaches currently are being used to deliver stem cells. The intracoronary infusion involves the infusion of cells into a coronary artery, usually during a brief coronary occlusion produced by inflating a balloon at the tip of the catheter. This method of delivery offers several advantages: (1) it results in a much more uniform distribution of cells within the infarcted region, (2) it does not require specialized training or the purchase of specialized equipment, and (3) it is technically easier, more practical and widespread

Genomic heterogeneity in tumors of different patients, it becomes increasingly evident that the diversity of cell types in tumor cell populations also likely plays a key role in drug susceptibility. I.e. subsets of tumor cell with distinct States of differentiation or with properties of "stem cells" may have distinctive sensitivity to drugs.(36, 37) In vitro studies have shown that this cellular heterogeneity can influence the response to treatment with anti-cancer agents.

Embryonic stem cell research has led to medical benefits to aid in curing diseases and many cancer cases that have grown in today’s society. Tissues throughout the body have a specific single layer of cells that can regenerate daughter cells. These daughter cells, or embryonic cells, have the capabilities to regenerate and build tissues or organs. These cells can aid in a lifelong regeneration process for tissues throughout the body. In vitro studies have shown that these cells can be placed in a specific area where there is large amounts of tissue damage due to injury or disease and completely rebuild this tissue into a completely new, fully functioning tissue. (Weissman, 2005, p. 1). However, people will argue the fact that embryonic stem cells have not been cleared to work in the human body. This is true that Weisman has only found it to work in mice and in genetically made organs, tissues, and muscle. Facts have shown that

In the past, stem cells transplants have been used in the treatment of genetic disorders such as leukemia and lymphoma. When this treatment is adopted, in this case the transplanted bone marrow is used to repair the ailing bone marrow. In such a situation, the bone marrow is asked to perform a different task, which is to repair another organ, which scientifically is an anatomical mismatch. Despite these setbacks, scientists continued to undertake research in this study and found out that stem cells can be used to cure diseases that in the past were termed as

Stem cells offer much hope for medical advancement because of their ability to grow into almost any kind of cell. Stem cells are crucial to develop organisms. They are non-specialized cells which have the remarkable potential to develop into many different cell types in the body during early life and growth. Because stem cell are a non-specialized cell can develop into any cell it wants within the organism it inhabits without limit to replenish other cells as long as the person or animal is still alive. Which mean under experimental condition, they can be induced to become tissue or organ- specific cell with special function? In some organs such as the gut and the bone marrow, stem cell regularly divide to repair and replace worn out or damaged tissues.

While radio- and/ or chemotherapeutic treatments are effective tools in treating certain cancers, a small population of cancer stem cells (CSC) can evade therapy which could be the reason for tumor recurrence and high rate of mortality. These CSC have the ability to bring the existence of new tumors and these are frequently found as multi-drug resistance (MDR) (Kawasaki et al., 2008). Chemotherapeutic drugs theoretically target the metastatic sites but current treatments do not exert significant therapeutic benefits in all cases (Soengas and Lowe 2003). Thus care should be taken to develop an alternative therapeutic strategy. Plant derived anticancer drugs are being considered more effective and safer for the patients, and do not have

The most important potential application of human stem cells is the generation of cells and tissues that could be used for cell-based therapies. Today, the demand for donated organs and tissues to replace ailing or destroyed tissue usually outweighs the available supply. Stem cells, directed to differentiate into specific cell types, offer the possibility of a renewable source of replacement cells and tissues to treat many diseases and damaged
