Stem cell controversy

Research into and the potential uses of stem cells The discovery of stem cells was a significant scientific breakthrough. They were first discovered in mice in 1981 and then in humans 17 years later in 1998. Stem cells have the potential to revolutionise modern medicine. They have the potential to offer cures for diseases, treating injuries that can’t be helped currently and dramatically change how drugs are developed. These possibilities have huge impactions to New Zealand as we have thousands…

Stem cells are cells that have the ability to self-renew and differentiate to become a myriad of different cell types. They serve as an internal repair system, with the purpose of replenishing or damaged cells. They can be found in various microenvironments within the tissues called stem cell niches cells, some examples of these include include the brain, bone marrow, blood vessels, skin, teeth, heart, amniotic fluid, umbilical cord, etc. Typically, there are only a small number of stem cells in…

Used Today Cloning is the artificial reproduction of a genetically identical copy of an organism. A clone is produced when DNA is extracted from the cell of the original organism, or “donor,” and inserted into an egg of the same species. The egg cell has had its nucleus previously removed and therefore it reads and duplicates the DNA of the donor cell. Since the first successful clone of an adult organism, Dolly the sheep, scientists have been experimenting with cloning others, such as mice,…

Genetic Engineering, Cloning, and Stem Cell Research Research over the last few decades has enabled scientists to identify the genes that compose the human body. Although this is a fascinating branch of scientific research, the numerous uses of genetic engineering carry with them many ethical questions. Some of the possible uses of gene manipulation listed by Boss (2013) include: cloning to produce or replace children or to create children with special qualities, manipulation of genes in order…

Askins 9/21/16 The Potential Use of Stem Cells To Treat Burn Victims ABSTRACT Extensive burns are devastating and if there is a way that we could use what our body already produces to help rebuild, wouldn’t that be wonderful? Stem cells allow us to regenerate a product that is just as good as the original. However, there are ethical issues with this treatment. INTRODUCTION A little bit of background on stem cells; they are defined as an undifferentiated cell of a multicellular organism that…

(NGC) which are the early forms of TENGs. NGCs are used in non-critical, small-diameter sensory nerve gaps of 3 cm or less. NGCs localize Schwann cell migration allowing the accumulation of trophic factors. Their small diameter allows for the diffusion of nutrients into nonvascularized areas, and the short length allows for complete permeation of Schwann Cells. In cases where nerve gap is less than 1 cm, results are better than those seen in autografts. But, neurons aren 't singularly linear…

Regenerative Capabilities of Dental Stem Cells Introduction – state hypothesis or problem and its scope (<1 page) Regenerative medicine aims to restore or establish normal function by replacing or regenerating human cells, tissue, or organs (Dunnill). Cell-based therapies are integral in regenerative medicine for the inherent ability of stem cells (SCs) to differentiate into specific cell types (Sedgley & Botero). SCs can be isolated during embryogenesis (embryonic SCs), or in postnatal…

Stem cell based treatment of neurodegenerative diseases The world of stem cells is extraordinary as they can differentiate into different types of cells and they come in different types of stages. stem cells can help with further treatments and research for cures. Embryonic stem cells which are the first stage of a stem cell are only around for a few days whilst in the embryo, then comes the adult cells in particularly mesenchymal stem cells that can be found in bone marrow or other particular…

large rise in stem cells research which has led to evidence of their remarkable potential. However, the use of stem cell in particular embryonic stem cells still remains a very controversial topic. Stem cells are undifferentiated cells that have the ability to divide and differentiate into many different kinds of cells. According to the national institute of health (2015), when a stem cell divides, each new cell has the potential to either…

Spine injuries and problems can affect the young and old alike. Be it trauma or issues associated with advancing age, these conditions can have a deep impact on the quality of life for the patient. A minimally invasive surgery can be termed as an endoscopic procedure that utilizes specialized cameras and instruments which can be introduced into the body through small incisions (usually less than 2 cm). As far as spinal surgeries are concerned, these incisions are typically made in the in the…
