The cell theory‚ or cell doctrine‚ states that all organisms are composed of similar units of organization‚ called cells. The concept was formally articulated in 1839 by Schleiden & Schwann and has remained as the foundation of modern biology. The idea predates other great paradigms of biology including Darwin’s theory of evolution (1859)‚ Mendel’s laws of inheritance (1865)‚ and the establishment of comparative biochemistry (1940).

Regenerative medicine Regenerative medicine is the process of replacing or regenerating human cells‚ tissues or organs to restore or establish normal function. It can be used for many things by many different techniques. It can benefit many different people in many different ways. Regenerative medicine replaces/repairs tissues that the body cannot repair on its own. This includes things such as organs like kidneys; if one needs to be removed we may be able to replace/repair it. Regenerative

are the general differences between private and public cord blood banks? Most private facilities provide an opportunity for donors to store their cord blood. This is in the hope that if‚ in the future‚ a member of their family becomes sick with a stem cell treatable disease‚ there might be a perfectly matched unit available to them. Other private banks collect cord blood in case that child develops a condition that could be treated with their own cord blood. For this service they charge an up-front

There are researchers‚ scientists‚ and doctors discovering ways to benefit the terminally ill and‚ in many cases‚ even cures for those people with the use of stem cells. Even though this may sound as though it would produce only a positive outcome‚ it is also a debatable subject. The majority of the vote against this research is due to moral issues.

This pales in comparison to China‚ Europe and the U.S.‚ which each report 100‚000 clients on average. The global market for stem cell therapies is expected to be $20 billion (Rs 92‚593 crore) by 2010. The current stem cell therapy market in India is approximately $540 million and it is expected to grow rapidly. This shows the scope in the market for stem cell banking. India is one of

If the cornea is scratched‚ healthy cells quickly heal the scratch before it gets an infection. If the damage is serious‚ the person can receive a cornea transplant. Also‚ scientists have discovered a new way to repair the cornea by using stem cells. 3. A cornea transplant is when a section of a damaged cornea is removed and replaced with a healthy cornea from a donor. Only about 20% of the

Amyotrophic lateral sclerosis‚ usually referred to as ALS or Lou Gehrig’s disease‚ is a condition that continually deteriorates motor neurons in the brain and spinal cord. Motor neurons are nerve cells that control muscle movements. When these nerves fail‚ the muscles they are supposed to communicate with don’t receive the full messages that are being carried from the brain or spinal cord‚ causing the muscles to stop working properly. Early symptoms of this disease include cramping or twitching of

I know that you are a little scared because you do not quit understand but luckily you have a friend like me who is going to shed some light on what I have learned on this subject. Now I know that you have not taken a science class since high school so I will break it down for you as much as I can. Stem cells have the capability to grow into different kind of cells while in the body either early or during the growth. What is so special about these cells arte that they
