Stem Cell Biology and Embryology – Exploring the Basic Principles

Stem Cell Therapy

Stem Cell Therapy (SC) is a relatively new medical therapy that focuses on the use of adult stem cells for the treatment of human diseases. These cells have the unique capacity to survive in an adult body and to reproduce after surgery, even in a stationary position. In fact, some stem cell types are so well suited to an adult body that they can actually outlive the person who gave them birth! However, for transplanting into an elderly person’s body, the doctor must make sure that these cells will give rise to a healthy adult human life.


the cloning of stem cells

Today, many medical disorders can be cured with the administration of stem cells from an adult donor. This is especially possible since these cells can be injected directly into a patient, newly harvested, or previously implanted, newly created, or otherwise grown from embryos. There have been many exciting advances in stem cell biology over the past several years, which have made possible the cloning of stem cells and the successful use of these cells in transplants. Cloning allows scientists to produce many healthy embryos to replace those destroyed in the process of a transplant. In addition, some stem cells are also able be used to treat cancer and immune system issues.


new cells to treat various illnesses or injuries

When stem cells are used in transplants, doctors preserve the embryos used in the procedure and then use these new cells to treat various illnesses or injuries. Stem cell transplants are very successful; however, there are always certain complications that can arise. For instance, there are two different classes of stem cells – embryonic and adult. The issue arises when doctors try to introduce embryos into a patient whose parents would prefer not to have their children used for this procedure. How can you find out whether you can have your children used for transplants, and what should you do if you discover that your parents would not want their offspring?


The study of Chimeras

There are many techniques for studying the different cell types and the different ways that they are used. It is also important to understand the difference between regular human cells, such as white blood cells, and specialized cell types such as Chimeras, and which are used in transplants. The study of Chimeras begins with studying the way that chimeras are created by animals.


A Chimera researcher

A Chimera researcher will look at the way that the animals create Chimeras. This can be done through induced reproduction or simply studying the methods of creation through more than one organism. Once the investigator has determined how animals create Chimeras, the next step will be to look at how the chimeras are produced in humans. This can be accomplished through tissue engineering, which consists of injecting stem cell biologists with DNA from one person and somatic cells from another person. After the DNA is introduced into the other person’s somatic cells, the DNA is copied exactly and is passed on to the next generation.


developing better living conditions for future humans

The next step involves harvesting Chimeras from humans and testing them for disease resistance and repairing defects. Then the embryos are returned to the embryo’s cell culture facility where a specific protocol is followed. If the Chimeras pass all of the standards set forth by the tissue engineer, then the embryos are released into the research lab and begin to develop into healthy adults. Stem cell researchers use the research findings to help develop medicines and cures for disease; it is a way to developing better living conditions for future humans.
