Stem Cell Research and its Implications LAS 432 Perry Furgason Shannon Johnson Kelly Hanson Kimberly Houser 10/05/2014 Introduction Stem cells are unspecialized cells that have the ability through cell division to become specialized cells. These cells possess regenerative properties for longer periods of time than other cells. And‚ in certain conditions can be induced to become tissue or organ specific cells. By seeking to understand their regenerative process‚ scientists can treat

fertilized egg cell divides millions of times to form the approximately six billion cells that make up the human body. These types of cells (4 to 7 day old embryo) are called embryonic stem cells that are unspecialized and have the ability to renew themselves and give rise to specialized cell types (they have not yet developed into cells that perform a specific function). A stem cell is uncommitted and remains that way‚ until it receives a signal to develop into a specialized cell‚ unlike a heart

Stem Cell Research Once an egg cell is fertilized‚ it will undergo division and become an embryo. As an embryo‚ stem cells that are able to becoming many types of cells in the human body. Scientist research by getting embryos in two ways. A couple’s sperm and eggs are fertilized on a experimental dish where the egg develops into embryos‚ which after are implanted in the female. The second way in which scientists get embryos is therapeutic cloning. This technique merges a cell with a donor egg. The

From the article we can know that both Roman Catholic and Islam have different opinions but their aim is the same‚ which is‚ improve human health. Also both of them agreed that the early stages of the biological development of the embryo are regarded as a human. Abdulaziz Sachedina from University of Virginia who represent view

We have learned so much information about animal’s genes and what can be done with them. However‚ with this new information brings new questions and arguments. So far‚ scientists have successfully cloned a sheep‚ a monkey‚ a bull‚ and are working on an endangered breed of ox‚ of course cloning animals and conducting research on those animals does

Introduction Human embryonic stem cells (hES cells) are currently discussed not only by the biologists by whom they were discovered but also by the medical profession‚ media‚ ethicists‚ governments and politicians. There are several reasons for this. On the one hand‚ these ‘super cells’ have a major clinical potential in tissue repair‚ with their proponents believing that they represent the future relief or cure of a wide range of common disabilities; replacement of defective cells in a patient by transplantation

ABSTRACT Stem cells have offered much hope by promising to greatly extend the numbers and range of patients who could benefit from transplants‚ and to provide cell replacement therapy to treat debilitating diseases such as diabetes‚ Parkinson ’s and Huntington ’s disease. The issue of stem cell research is politically charged‚ prompting biologists to begin engaging in ethical debates‚ Stem cell research offers great promise for understanding basic mechanisms of human development and differentiation
Premium Stem cell Cellular differentiation Developmental biology
difference between embryonic stem cells and adult stem cells is that an embryonic stem cell is not fully developed and with no specific cell tissues. Embryonic stem cells are found in the inner cells mass of the early embryo. The very first embryonic stem cells are totipotent (can be able to create all kinds of cells) but the rest after that are pluripotent which means that it can create many different types of cells such as white blood cells‚ nerve cells‚ and neurons. Adult stem cells are less flexible than
