Cell therapy and organ repair is a significant issue because most human organs and tissues do not regenerate spontaneously. Several categories of stem cells can be used in regenerative medicine including embryonic‚ fetal‚ and adult stem cell. Not all stem cells are of equal interest for clinical applications‚ because they are not able to become different specialized cells. Fetal and adult stem cells are undifferentiated cells‚ which can be found within fetus or in adult tissues or organs. They have

STEM CELLS Where are stem cells sourced from? Stem cells are sourced from three main sources‚ Embryos‚ bone marrow and umbilical cord blood. Each different sources’ Stem Cells are either totipotent‚ pluripotent or multipotent. Refer to Figure 1 Figure 1 Stem Cells can be categorised into their capability of being cultured into a different cell. Embryonic Stem Cells: Are pluripotent cells meaning they can be cultured into most cell types. The Embryonic Cells are sourced from in the internal cell

what a stem cell is. There is a lack of health literacy in our nation. So the public can’t really get into this dialogue because they don’t understand the complexity of stem cells‚ not the faith based approach‚ not the ideological or political‚ but the science behind stem cells.” Stem cells have the unique ability to transform themselves into whatever type of cells that are needed. They can be the cure for cancer‚ repairing tissue and treating diseases. As we discuss this topic of stem cell research

Stem Cell Research Legislation and Related Legal Issues DeVry University The first embryonic stem cells were first isolated from animals in 1981 by Sir Martin Evans. However it wasn’t until 1998 that James Thompson first isolated human embryonic stem cells. Since then continuing research with stem cells has shown to be sensitive issue because of the perception of morality by humans. For this reason stem cell research legislation has been enacted and has been ever changing throughout time. Therefore

SANCTITY OF LIFE We all have different viewpoints when it comes to Embryonic Stem Cell Therapy. Majority of the individuals believes that it violates the sanctity of life because they consider the act of destroying a human blastocyst is equal to killing a human being. Embryos are considered humans from the moment of the union of the gametes; hence‚ it can be relayed as the weakest members of society. It is morally wrong to exploit the weak merely because some benefit can be derived from it

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

Reaction Paper on Stem Cell Ibilola Aridegbe Coun502 Dr. Marcia Wiinamaki 01/27/2009 Human existence begins at conception Abstract The purpose of this research includes a brief overview of information found through Intoduction Stem cell research has brought about heated debate among academics and society as a whole. Especially among Christian circles. Embryonic stem cells are derived from embryos that develop from eggs that have been fertilized in vitro or at an in vitro fertilization clinic

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

the ethical controversies surrounding embryonic stem cell research are profound. Stem cells‚ the cells used by the human body to replenish damaged tissue‚ are found in both embryonic and adult form. At the adult level‚ stem cells can be extracted from bone marrow‚ but the real ethical debate arises when embryonic stem cells are introduced. “Pluripotent” embryonic stem cells are among the only type that can form any of over 200 cell types‚ making it the most useful and versatile. These cells are isolated

Define Stem Cells and give background information on them. Stem cells are a class of undifferentiated cells that are able to differentiate into special cell types. There are two types of Stem Cells: Adult Stem cells and embryonic stem cells. Embryonic stem cells come from embryos that are 3-5 days old. They are often taken from the umbilical cord. They are used more than adult stem cells. Adult stem cells mainly come from bone marrow. Their primary function is to maintain homeostasis by replacing
