Sickle cell disease and the hope of stem cell therapies; ethics in the treatment sickle cell. The past half century has been an era of rapid discoveries: from the humble beginnings of molecular biology‚ discovery of the structure of DNA‚ research on recombinant DNA‚ the discovery of the human embryonic stem cell (ESC)‚ the completion of the Human Genome Projects‚ mammalian cloning and the discovery of ntESCs (nuclear transfer ESCs) by somatic cell nuclear transfer and the ethical sigh of relief

CELL INJURY: CAUSES OF CELL INJURY‚ MECHANISMS OF REVERSIBLE AND IRREVERSIBLE CELL INJURY. CELL INJURY. Causes of cell injury range from gross mechanical external causes to mild endogenous causes as genetic lack of enzymes etc. Virtually all forms of tissue injuries start with molecular or structural alterations in cells. Under normal conditions‚ the cells are in: ❖ homeostastatic „steady“ state Normal cell is confined to relatively narrow range of functions and structure by

HeLa Cells are Important to Science Henrietta Lacks‚ a poor black woman in the 1950’s‚ unknowingly had samples taken from her cervical cancer specimen and changed science from that point on. Due to the continuous self-reproduction of the cells‚ HeLa cells are the most important cell line ever discovered by scientists to date! Popsci.com gave five reasons of why HeLa cells are so important to society. Popsci.com explained‚ “1. Before HeLa cells‚ scientists spent more time trying to keep cells alive

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

In 1968 he made a revolutionary discoverie. He discovered the type II restriction enzyme‚ witch had major impacts in 2 fields of science. Gene cloning‚ and DNA fragmentation. Gene cloning is what it sounds like; cloning genes. He essentially made a discovery that allowed the first gene to be cloned. The second field that was impacted by this discovery was DNA fragmentation. DNA fragmentation is most commonly used in testing men’s sperm to see how fertile they

Portfolio The Cell and Cell Theory [pic] The cell The word cell comes from the Latin word “cellula”‚ which means a small room. The cell is the smallest unit of a living organism‚ also known as “the building block of life”. Every living organism is consisted of a cell. There are bacteria (unicellular organisms)‚ and multicellular organisms. There are different types of cells‚ prokaryotic and eukaryotic cells. All cells come from preexisting cells. “Every cell is self-maintaining;

Your genes are not your destiny. In the latest mega-study‚ researchers at King’s College London‚ followed over 13‚000 pairs of twins over a period of 12 years and came up with a genetic and environmental hotspot map showing that the weighting given to genetics versus environment in one’s development is strongly influenced by one’s geographic location. At first blush‚ these findings sound fairly obvious. After all‚ isn’t the whole point of nature versus nurture to show that environment plays as
