Cloning Should Have Limits - Cloning Should Have Limits "Mary had a little lamb, it fleece was slightly gray. It did not have a father, just some borrowed DNA" (Pence xv, par. 1). According to the article ("Cloning Milestones"), Dr. Hans Spemann visualized cloning back, in 1938 (121). Historical events from 1938 to 2005, provides evidence, that cloning is no longer a vision. Cloning is today's reality. The medical evolution related to the technology of cloning has generated ethical, moral and religious debates for decades....   [tags: Cloning DNA Ethics Stem Cell Research] 1515 words

Panacea - Panacea Panacea- n. a cure for all ills, a universal remedy [Webster’s 724]. Embryonic stem cell research has been one of the most heavily and intensely debated topics in the past five to ten years. Although it is not literally a cure for all sicknesses, it holds the key to the most exciting medical advances in the last 100 years. The controversy surrounding stem cell research is such a huge deal because of the moral dilemma surrounding it. There is no doubt that everybody would like to have cures for ailments ranging from paralysis to Alzheimer’s but they must be willing to side with science for the betterment of mankind....   [tags: Stem Cell Research] 1515 words

Extremely Useful and Harzard of Stem Cells - ... Adult stem cells, adversely, are multipotent stem cells that derive from developed body tissues. They are grown less and slower in comparison to embryonic stem cells. Stem cells' distinctive quality of being able to reproduce themselves and essentially forming into any type of body cell they desire (differentiation) makes these cells both extremely useful and extremely hazardous. Despite their immense uses, stem cells are increasingly controversial due to all of their possible contributions to life....   [tags: adult, embryonic, reproduce, cell] 596 words

Role in Inducing and Maintaining the Pluripotency of Mice Embryonic Stem Cells - Several members of the zinc finger family of proteins are key components in the transcriptional network maintaining pluripotency in embryonic stem cells. The mouse zinc finger protein 322a (Zfp322a) is expressed in embryonic stem cells and the ICM. Thus Ma et al. 2014 hypothesized that Zfp322a functions as a transcription factor in mice. Ma et al. (2014) discovered that Zfp322a is an irreplaceable transcription factor which enhances the reprogramming ability of OKSM (Oct4,  Klf4, Sox2, and c-Myc) and can replace Sox2 in OKSM in the generation of induced pluripotent stem cells (iPSCs)....   [tags: zinc finger, mouse stem cells ]

Embryonic Stem Cells and Adult Stem Cells - Embryonic stem cells are a different class of stem cells. ‘Stem cells’ are primitive cells with the capacity to divide and give rise to more identical stem cells or to specialize and form specific cells of somatic tissues. However, two types of stem cell can be distinguished: embryonic stem cells (ES): can only be derived from pre‐implantation embryos and have a proven ability to form cells of all adult tissues (termed ‘pluripotent’). ‘Adult’ stem cells, which are found in a variety of tissues in the fetus and after birth and are, under normal conditions, more specialized, which is revered to as “multipotent.” The embryonic stem cells can assist with tissue replacement and repair....   [tags: genetic engineering and health] 909 words

Conditions such as degenerative disk disease could be effectively treated without the need for long term medications to decrease the chance of host rejection, spinal surgeries, and would greatly improve the quality of life of the individual by continuing mesenchymal stem cell research....   [tags: treatments, bone marrow transplant, therapies]

Hematopoietic Stem Cells - ... Osteoblasts are bone- forming cells that line the bone-surface. HSCSs are present in close association with osteoblasts (Gong, 1978). First evidence indicating osteoblast as HSC niche came from the study of Taichman and Emerson in 1994. They found that human osteoblast can support hematopoiesis in vitro (Taichman and Emerson, 1994). Subsequently, two independent studies revealed that increase in the number of osteoblasts results in the expansion of number of HSCs. Elevation in the number of osteoblasts was achieved genetically by either the conditional ablation of a BMP receptor type 1a (BMPr 1a) or by the activation of parathyroid hormone-related protein receptor (PPR)(Calvi et al., 200...   [tags: nervous system in the HSC niche] 734 words

Studies have shown that stem cells reduced some effects associated with Parkinson’s. A study taking human cord blood cells and using them on mice affected with Alzheimer’s showed the stem cells migrating to the affected parts of the brain and reducing the beta amyloids. The effectiveness of this study on mice has led to trials with humans also.

These stem cells are of extreme potency because they can self-renew in culture while maintaining the capability to become virtually any cell type (Zhu and Huangfu, 2013). While there are many ethical concerns regarding embryonic stem cells, induced pluripotent stem cells arise from adult somatic cells that can be reprogrammed to enter the pluripotent state and have similar characteristics of embryonic stem cells such as having normal karyotypes, expression of telomerase activity, cell surface markers and genes, as well a...   [tags: the potential to change medicine]

Stem Cells - What is a stem cell. Stem cells have the ability to divide for indefinite periods in culture and to give rise to specialized cells. They are best described in the context of normal human development. Human development begins when a sperm fertilizes an egg and creates a single cell that has the potential to form an entire organism. This fertilized egg is totipotent, meaning that its potential is total. In the first hours after fertilization, this cell divides into identical totipotent cells. This means that either one of these cells, if placed into a woman's uterus, has the potential to develop into a fetus....   [tags: essays research papers] 2840 words
