Introduction to Biology: SCI115 11/08/2015 The article “Therapeutic Cloning, and stem cell Research” by Gena Smith is about how we can extract stem cells from replicated human embryos and use them for medical and therapeutic purposes. The stems cells are perfect because they are what the article calls “master cells” which with the help of science, can be manipulated to become anything from brain cells to kidney cells. The article also revolves around the amount of controversy over the issue of cloning

rejuvenation in previously irreparable organs. The process begins by taking adult stem cells from a damaged organ or tissue sample, and combining them with an organic structure so the cells may replicate the organ or tissue that they originated from. Each cell has its own chemical make-up which will predetermine its eventual fate – thus a stem cell from a liver will begin the foundations for a new liver, whilst skin stem cells will grow to produce more skin. Regenerative medicine is key to the advancement

Stem cells are undifferentiated biological cells that can differentiate into specialized cells and can divide (through mitosis) to produce more stem cells. They are found in multicellular organisms. In mammals, there are two broad types of stem cells: embryonic stem cells, which are isolated from the inner cell mass of blastocysts, and adult stem cells, which are found in various tissues. In adult organisms, stem cells and progenitor cells act as a repair system for the body, replenishing adult tissues

News science and environment August 5 , 2013 The world's first lab-grown burger has been cooked and eaten at a news conference in London. Scientists took cells from a cow and, at an institute in the Netherlands, turned them into strips of muscle that they combined to make a patty. One food expert said it was "close to meat, but not that juicy" and another said it tasted like a real burger. Researchers say the technology could be a sustainable way of meeting what they say is a growing

Egg Makes Sure That Sperm Don't Get Too Old The article primary’s claim is that the result is an important step towards future stem cell therapy (science daily). I. Observe and Generalize: • I would like to learn more on how men are fertile throughout life. I would like to find out the how this is a contrast to women? II. Hypothesis: • The subject and/or hypothesis of this claim, is that the fertilizing sperm can get help from the egg to rejuvenate (science daily). III. Experiment

source of stem cells, considered to be the master cells of the body. Under the right conditions, these immature, “undecided” cells can be transformed to virtually any type of cell in the human body. For nearly two decades, these cells have been used in transplant medicine to treat more than 80 serious diseases, including leukemia and other blood disorders and cancers. Scientists at leading universities in the U.S. are exploring a growing list of other potential uses for cord blood stem cells. One of

increases the likely hood of multiple blastocysts merging to become one organism. Moreover, developments in cellular research stem cell research, and cross species transplants has brought the possibility of human-nonhuman into the forefront of scientific research for which we are ill prepared. There are three dilemmas that are shaping public policy, and constraining scientific research. These dilemmas are political, ethical, and moral. As we work to answer these dilemmas, we also stumble to maintain

office has requested a think tank team of criminologists to review the research documents of new technology computer-aided microscopic rare gene molecules. The team of criminologists will consider the legal or not legal aspects of the doctor’s request for a patent, along with the viability of current transplant procedures. The scenario states the doctor has invented a computer – aided organism as key to bridge the new cells to human organs in the host receiver. This is a new concept of using microscopic

STEM CELL RESEARCH AND THERAPYAND ITS IMPACTS ON SOCIETY Abstract There are several types of stem cells being used in stem cell research and therapy today. They are embryonic, adult and induced pluripotent stem cells. Each will be discussed further. This topic has stirred much moral, ethical and political debate as whether cells from fetuses should be used in this research. This impacts governmental policies on laws and funding. Another issue that must be analyzed is the economics and who
