Those stem cells, as it turns out, could perhaps one day provide a miraculous medical treatment to regenerate an organ for you, strengthen your immune system or even treat your disease. I’d call that a savings you might want to bank on or at the very least . . . learn more about!
Is it ethical to use stem cells?
Using human embryos for research on embryonic stem cells is high on the ethical schedule in many countries, while adult stem cells are not nearly so high on the scale. Even though the benefit of using human embryonic stem cells is the potential treatment of diseases, their use remains controversial because they originate from early embryos (de Wert & Mummery, 2003).

Stem cells are the body's master cells. All other cells arise from stem cells, including blood cells, nerve cells and others.
Why is there a controversy about using embryonic stem cells?
Embryonic stem cells are obtained from early-stage embryos — a group of cells that forms when a woman's egg is fertilized with a man's sperm in an in vitro fertilization clinic. Because human embryonic stem cells are extracted from human embryos, several questions and issues have been raised about the ethics of embryonic stem cell research.
Why can't researchers use adult stem cells instead?
Adult stem cells may not be able to be manipulated to produce all cell types, which limits how adult stem cells can be used to treat diseases.
What are stem cell lines and why do researchers want to use them?
A stem cell line is a group of cells that all descend from a single original stem cell and are grown in a lab. Cells in a stem cell line keep growing but don't differentiate into specialized cells. Ideally, they remain free of genetic defects and continue to create more stem cells. Clusters of cells can be taken from a stem cell line and frozen for storage or shared with other researchers.
What is stem cell therapy (regenerative medicine) and how does it work?
Stem cell therapy, also known as regenerative medicine, promotes the repair response of diseased, dysfunctional or injured tissue using stem cells or their derivatives. It is the next chapter in organ transplantation and uses cells instead of donor organs, which are limited in supply.
Have stem cells already been used to treat diseases?
Yes. Doctors have performed stem cell transplants, also known as bone marrow transplants. In stem cell transplants, stem cells replace cells damaged by chemotherapy or disease or serve as a way for the donor's immune system to fight some types of cancer and blood-related diseases, such as leukemia, lymphoma, neuroblastoma and multiple myeloma. These transplants use adult stem cells or umbilical cord blood.

What is stem cell research?
Stem cell research is helping scientists understand how an organism develops from a single cell and how healthy cells could be useful in replacing cells that are not working correctly in people and animals.
Why is a stem cell considered an undifferentiated cell?
Scientists call a stem cell an “undifferentiated” cell because it can become any cell. In contrast, a blood cell, for example, is a “differentiated” cell because it has already formed into a specific kind of cell.

Another way that scientists could use stem cells is in developing and testing new drugs.
What is a reprogramed stem cell?
Those reprogramed stem cells are called induced pluripotent stem cells (iPSCs). Throughout the life of the organism, populations of adult stem cells serve as an internal repair system that generates replacements for cells that are lost through normal wear and tear, injury, or disease.
What are the different types of stem cells?
There are several main categories: the “pluripotent” stem cells (embryonic stem cells and induced pluripotent stem cells) and nonembryonic or somatic stem cells (commonly called “adult” stem cells). Pluripotent stem cells have the ability to differentiate into all of the cells of the adult body.

To be useful for transplant purposes, stem cells must be reproducibly made to: Proliferate extensively and generate sufficient quantities of cells for replacing lost or damaged tissues. Differentiate into the desired cell type (s). Survive in the recipient after transplant.
How can stem cells be used in medicine?
To realize the promise of stem cell therapies in diseases, scientists must be able to manipulate stem cells so that they possess the necessary characteristics for successful differentiation, transplantation, and engraftment. Scientists must also develop procedures for the administration of stem cell populations, along with the induction of vascularization (supplying blood vessels), for the regeneration and repair of three-dimensional solid tissues.
What is the role of trophectodermal cells in the placenta?
The trophectodermal cells contribute to the placenta. The inner cell mass will ultimately develop into the specialized cell types, tissues, and organs of the entire body of the organism. Previous work with mouse embryos led to the development of a method in 1998 to derive stem cells from the inner cell mass of preimplantation human embryos ...
How long do stem cells stay quiescent?
These stem cells may remain quiescent (non-dividing) for long periods of time until they are activated by a normal need for more cells to maintain and repair tissues. II.
Why do scientists use stem cells?
Scientists can use stem cells to learn about human biology and for the development of therapeutics. A better understanding of the genetic and molecular signals that regulate cell division, specialization, and differentiation in stem cells can yield information about how diseases arise and suggest new strategies for therapy. Scientists can use iPSCs made from a patient and differentiate those iPSCs to create “organoids” (small models of organs) or tissue chips for studying diseased cells and testing drugs, with personalized results.

Scientists generally agree that a stem cell should be able to do both of the following: Self-renew: divide into another stem cell, which means making an identical copy of itself ; and. Differentiate: change into a variety of other cell types. One theory of ageing suggests that between the ages of 30 and 50, our stem cells reach a turning point ...
How long after conception do embryonic stem cells grow?
1. The embryonic stem cells are harvested 5-7 days after conception.#N#Adult stem cells do not provide the same benefits as embryonic ones from a therapeutic standpoint. They fall short in their viability to treat genetic diseases. That’s because the same disease found in the adult body can be present in their stem cells. When the harvesting takes place, it occurs during the first week after conception. At this stage, the embryo has not yet developed to a stage where a personal identity can be assigned to it, nor can it live outside of a specialized environment. It is essentially a mass of cells.
How do embryonic stem cells form?
Human embryonic stem cells come from a transference of cells from a preimplantation-stage embryo in a laboratory culture dish. It is mixed with culture medium, allowing the cells to divide, and then spread over the surface of this dish. These cells can then develop into all three derivatives of the primary germ layers, making it possible for them to eventually turn into one of the over 200 different cell types that are found in the human body.
