“Stem cell research can revolutionize medicine, more than anything since antibiotics.” This statement was said by former president of the United States of America, Ronald Reagan. Mr. Reagan in this statement was saying that stem cells are the future of medicine and can change how the medical field may approach a problem. Stem cells are cells that have the potential to develop into different kinds of cells. Stem cells have an internal repair system. They can also replenish other cells. There are…

avoid contamination must be followed. Further, the data collected for table 1 was made by approximating the developmental stage of the chick embryos instead of using the Hamburger and Hamilton table, this left us with data that was unreliable and we were unable to use because the factors we used to data the chicks such as size, are largely impacted by genetics and not good markers for developmental staging. We would need to repeat this experiment and use a larger sample size in order to…

Embryonic stem cells are very controversial in the scientific community and as well as the medical community for many reasons. “Stem cells are cells that can be any cell that the human body needs to be”,(Rowlery,usnews.com). For example, a stem cell can be a skin cell, a liver cell and or a bone cell. The reason why embryonic stem cells are extremely controversies is because the cells come from human embryos. To obtain theses types of cells a mother need to have an abortion, and doctors and…

The operations of cloning have brought out an abundance of fundamental milestones laying concrete on rearing onto the likelihood for an acceptance of therapeutic cloning. There exists a manifold quantity for the, “applications of this technology in nonhuman animal models will undoubtedly contribute in a major way to vaccine development and the unraveling of teratological and genetic problems in human development as well as impacting wildlife conservation efforts” (Wolf, Meng, Ely, & Stouffer,…

Gurdon was born on October 2nd 1933, in Dippehall United kingdom. He is an English developmental biologist. He was awarded a Nobel Prize in 2012 for his research on how mature cells can be reprogrammed to become pluripotent. Sir Gordon in his research wanted to show the capacity nuclei taken from intestinal epithelium cell of feeding tadpole…

TITLE PAGE EXECTUTIVE SUMMARY CONTENTS PAGE INTRODUCTION CASE STUDY REPORT BODY BIOPRINING- Design concepts- Bioprinting is the three-dimensional printing of biological tissue and organs through the layering of living cells. While this area of manufacturing is still in the experimental stage and is currently used primarily in scientific study rather than applied science, the possibility of creating functional replacement…

2.1. Artificial Insemination (AI) : Development of techniques for successful. .freezing of spermatozoa has progressively evolved over the. . Past 60 years (Kucuk et al., 2014). At the starting of 20th century Ivanov started studying on artificial insemination (AI) of sheep’s, where Ivanov’s .studies on extenders and reproduction resulted in the development and the practical application of AI in farm animals, reviewed by (Bohlooli et al., 2012). AI provides. .many advantages to farmers and…

Clonality is homogeneity in the genotype of cells originating from a specific linage. One cell like the other, expressing the same set of genes to carryout functions that they have to do as a tissue; a causality of cells having a common ancestor or a progenitor cell which can be sourced at one point in time of development of an organism. This expansion of one cell into various clones occurs via a process called clonal expansion. The process is not different in cancer cells, there is one cell…

Stems Cells The use of stems cells has caused immense controversy among humanity over the years. There is a very thin line between the use of stem cells for science purposes and the morality of using stem cells, even for the reasons of science. The argument surrounding the use of stem cells, like any argument, has two sides to the argument. There are those who are in favor of the use of stems, and there are those are against the use of stem cells with arguments that support both opinions; I…

totipotency, pluripotency and multipotency (Pei, Xu, Zhuang, Tse, & Esteban, 2010). Figure 1: Developmental potential of stem cells. Totipotent cells are cells that have the potential to produce the whole organism, which, in essence, is the zygote. As the cells develop, the developmental potential decreases as specificity increases (pluripotent-multipotent-unipotent). With cellular reprogramming, developmental potential can be…
