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

Stem cells‚ often called the building blocks of the human body‚ are positioned within the body’s blood‚ tissues‚ organs‚ and immune system. Once they are transplanted‚ they have the capability to either reconstruct or restore a patient’s damaged cells which could enhance the patient’s health; and in some cases can conclusively save a person’s life. The umbilical cord is used as a basic lifeline from the mother to the baby throughout the pregnancy. If stem cells from the umbilical cord are collected

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

Medical Issues- Stem Cells Click on The Nature of Stem Cells to answer the following questions. 1.) Compare a stem cell and a specialized cell. Specialized cells carry out specific functions. These specialized cells are called differentiated cells. On the other hand‚ a stem cell is undifferentiated. Its role in the body is not yet determined. A stem cell can give rise to multiple cell types‚ including many stem cells. 2.) Describe a blastocyst. The blastocyst looks like a lopsided hollow ball

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

2013 Stem Cells A Better Future for Tomorrow The field of human genetics has been a “hot topic” since the 1950’s when James Watson and Francis Crick first discovered the basic structure of DNA (“Human Genetics”). Stem cells are found in humans and animals that have distinctive properties. They are the building blocks of life simply put. They have the ability to divide and reproduce themselves for a long period at a time. Stem cell research is a very controversial topic‚ and for a good reason

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

First‚ where do stem cells come from‚ and what properties do they exhibit that make them stem cells? Human embryonic stem cells come from an embryo that develops from an egg. These eggs were originally collected for reproductive purposes. The eggs are fertilized in vitro‚ and the embryo is donated for research. The donation only happens after the eggs are no longer needed. The donor is informed of the intended use‚ and consent has been given. These stem cells are found when the embryo is between
