Adult Stem Cells vs. Embryonic Stem Cells. Search this site.
Adult stem cells are undifferentiated cells found throughout the body that divide to replenish dying cells and regenerate damaged tissues. Research into adult stem cells has been fueled by their abilities to divide or self-renew indefinitely and generate all the cell types of the organ from which they originate — potentially regenerating the entire organ from a few cells. Unlike embryonic stem cells, the use of adult stem cells in research and therapy is not controversial because the production of adult stem cells does not require the destruction of an embryo.
Dev Reprod ; 21 1 : 1 - The use of human mesenchymal stem cells hMSCs in cell-based therapy has attracted extensive interest in the field of regenerative medicine, and it shows applications to numerous incurable diseases. Different cell types are discussed in terms of their advantages and disadvantages, with focus on the characteristics of hMSCs.
Stem cell research takes two primary forms: adult stem cells and embryonic stem cells. Each cell line that is harvested offers the opportunity to develop new treatments that may help to stop a plethora of diseases that affect humanity. One of the primary advantages of stem cell research is the availability of cell lines and that they can be obtained ethically. Adult stem cells can be harvested from healthy individuals by accessing their bone marrow and other tissue sources.
Skip to content. In conclusion, the development of stem cell research is important. There are clearly more advantages than disadvantages but this should not mean that the disadvantages are insignificant.
Jump to navigation. Human embryonic and adult stem cells each have advantages and disadvantages regarding potential use for cell-based regenerative therapies. One major difference between adult and embryonic stem cells is their different abilities in the number and type of differentiated cell types they can become.
Adult stem cells can be found in tissues in the body, including, marrow, skin, brain, skeletal muscle and liver cells. An adult stem cell is an undifferentiated cell that can replicate itself and repair a damaged tissue. Having said this, scientists believe that adult stem cells can play a significant role in the science of medicine.
Most cells in the body are differentiated cells. These cells can only serve a specific purpose in a particular organ. For example, red blood cells are specifically designed to carry oxygen through the blood. All humans start out as only one cell.
Debates over the ethics of embryonic stem cell research have divided scientists, politicians, and religious groups for years. However, promising developments in other areas of stem cell research have led to solutions that help bypass these ethical barriers and win more support from those against embryonic stem cell research; the newer methods don't require the destruction of blastocysts. Many parties continue to have strong opinions that trigger ongoing debates about stem cell research, and the following pros and cons provide a snapshot of some the points on each side of the issue.
July, Three years ago, research teams in the United States and Japan reported that they had reprogrammed adult human cells to form pluripotent stem cells—cells capable of differentiating into all cell types. Scientists were elated. Researchers working with the cells still must countenance certain ethical concerns, and they may also face newly discovered scientific hurdles. At Hopkins, such issues have prompted a change in the committee that was formerly charged with overseeing human embryonic stem cell research.
