Stem cell controversy

During this lab observations of the external and internal structures of seastars were examined through dissection. Most notably, seastars are creatures that are deuterostomes. First of all, deuterostomes are organisms within Echinodermata and Chordate phylum that developed anus first. The egg for echinoderms have a little quantity of yolk that allows the egg to divide in its first and second cleavage stage into four equal blastomeres; this is also known as holoblastic cleavage. Although, if the…

Embryonic stem cell research. Google this term and you will find that there are as many articles on the ethics of embryonic stem cell research (ESCR) as there are on the actual biomedical field of study. The moral claims for and against the use of embryos in scientific research often deal with “personhood”. Opponents of ESCR mistakenly equate ‘human life’ and ‘personhood’. I will dive into the semantics of these terms in the following paragraph. Opponents of ESCR also suggest that embryos are…

Even though some philosophers think human embryos are like stem cells due to the lack of rational nature, they have the full potential and ability to have a rational nature. If human embryos don't have a rational nature neither do stem cells. If one decides to destroy a human embryo, then its potential is interrupted. Compared to stem cells, human embryos have a probability to become an adult which gives it a chance to reason and make choices for itself in the future. With this argument, human…

deep discussion about stem cells he must understand some of the key terms involved in stem cell research. The first term is totipotent. Totipotent cells are the cells of the zygote. These cells are able to develop into any type of cell inside or outside the body. An example of cells that are considered outside the body is the placenta. The ability for totipotent cells to develop into cells outside the body is what separates it from pluripotent cells. Pluripotent cells also have the ability…

needed breakthrough.” This medical discovery is better known as stem cell research, more specifically, the study of stem cells for medical applications. Stem cells are a special category of cells that are able to differentiate into specialized cell types, but also retain the ability to renew themselves through cell division. However, most of the controversy surrounding stem cell research is based on where stem cells are derived from. Stem cells normally come from two main sources, three to five…

have arisen over time. It is therefore, important to look further at the ethical and economic issues that have triggered slower acceptance of gene therapy. Danquah, Michael K. and Ram I. Mahato. “Emerging Trends in Cell and Gene Therapy.” Springer…

Nuclear Chemistry: The Magnetic Resonance Imaging The evolution of medicine is quite interesting. It first started out with spirits, omens, and other mythical beliefs. Then, the discovery of science has allowed for more practical ways to examine and heal a body. First the simple tools came into play, then the advanced technology. As the years keep progressing, more and more discoveries are being made. One example of this is magnetic resonance imaging (MRI). Nuclear chemistry has allowed for…

replacement organs. “These stem cells-or the specialized cells derived from them will be genetic match to the patient. Therefore, the promise of SCNT is that the patient 's body would accept these cells after transplantation.”(The Value of Therapeutic Cloning.) Cloning is a process in which genetically identical copies of biological matter are created through nonsexual means. Clones are made up of organisms that are exact genetic copies. Every piece of their DNA is identical. Cells, genes,…

engineer tumor cells in the laboratory, then test various drugs to see which can stop them from growing.” It supports this argument because it mentions that the CRISPR-Cas9 technology can operate the genome by testing different drugs to see which can stop the growth of cancer. Furthermore, it does not only provide a set of readily programme tools, but can also infer that this technology has already transformed to check about the cancer research as it is easier to examine the tumor cells in the…

Capillus 202 Review - Any Hair Restoration Benefit? Does Cost More for 202 Laser Diodes! Capillus 202 is another laser based device that claims to reverse thinning hair and re-grow lost hair. It is marketed in the manufacturer’s primary website and in known retail website(s). I could find a good number of details about this device where it claims to offer several other benefits when it comes to hair restoration. My task here is to put this information together and say if the product is worth…
