Added for You - Stem Cells: The Fountain of Youth
Looking for that ideal home is like shopping for any basic necessities or big luxury items---you have to remember to first look around, compare costs, terms, savings, or to negotiate for the best deal. This is when a home buyer guide can help you know what to do to make the process smooth and uncomplicated and what to look out for to save you from frustrations or delays in getting that house you want.One good advice in the home buyer guide is: Figure out how much cash you can and are willing to pour into acquiring a home. Arriving at a decision to buy a home will involve a significant amount of investment not only in money but also of your time. The cash
How are stem cells obtained?
Cell cultures are grown in the laboratory by transferring the inner cell mass of about 30 cells into a culture dish which has a nutrient broth. The cells quickly multiply and fill the dish. They are then transferred to other culture dishes and the process goes on for months.

Not too long ago, I walked into a room where some of the country's top oncologists were preparing to launch a new cancer-fighting drug. The occasion was the group's rehearsal before a big presentation to the Federal Drug Administration. Given that these men and women are some of the best and brightest in their field, I thought the rehearsal would be a breeze. So, I sat down, pen poised to make a few notes so I could help them fine-tune their presentations and be ready for the onslaught of media that was sure to follow.What a letdown. Five articulate, highly educated, well-dressed presenters, armed with shiny animated slideshows, droned on and on and on and o

What are stem cells?
The question should be phrased in terms of embryonic stem cells because that is what we are talking about here.
A human embryo is obtained when a woman’s egg is fertilized by a man’s sperm. This occurs in the human body but it can also be done in a laboratory. The procedure is often used in cases of infertility.
I have three grandchildren formed in this way. Their mother donated eggs, their father donated sperm, and the technicians watched the fertilization take place under a microscope. The fertilized eggs were placed in the mother and she gave birth to triplets.
If embryos formed in this way are not placed in the mother they can be and are used for medical research. Often extra fertilized eggs are produced during this process. Scientist would like to harvest these extra eggs rather than discard them. They could then use them to obtain stem cells.
Stem cells are never obtained from fertilized eggs that reside in a woman’s body.
The embryos obtained after they are a few days old are in the form of a mass of cells called a blastocyst; the embryo of about 150 cells. The blastocyst consists of a sphere made up of an outer layer of cells (the trophectoderm), a fluid-filled cavity (the blastocoel), and a cluster of cells on the interior (the inner cell mass).

The world of real estate is growing by leaps and bounds. This has also led to the development of new and improved innovative buying methods in terms of making an investment. The real-estate investment industry is increasingly seeing the rise of numerous investment groups or clubs. These are essential a collection of like-minded investors who pool together resources to make a real estate investment.Though this is a new concept, it is becoming a popular choice. This is because of the numerous associated benefits that you can get. One of the basic advantages is that you meet investors from around the world who have the same thoughts on a particular project as y

If you are financially minded but unfamiliar with what a reinsurance job might entail we’ve compiled four reasons why companies carry out reinsurance and the two main different types of reinsurance.Four Reasons for ReinsuranceRisk Transfer – you only have to look at the amount of money an insurance company would have to pay out if your house was damaged in a natural disaster to realise how there is the potential for them to have huge costs. By reinsuring themselves with other insurers they are able to spread the risk so that no matter how many of their policy are claimed upon they have the ability to pay out.Inco

If you are considering attending law school then your law school essay, along with of course your LSAT score and your undergraduate record, is going to go a long way in deciding which schools will consider accepting you and how much scholarship money they will be prepared to offer you.Many schools assign different standards of important to the various requirements. Your LSAT score and GPA have a big impact, law school essays are definitely taken into account. What's more than that, your law school essay can really make or break your admission acceptance, and if it is strong on can't even overcome weaker academic achievements.It is not unheard of tha

Once the cells are obtained they can be frozen and shipped to other laboratories.
What other potential stem cell sources are there?
Adult stem cells are a potential source. They can be used to reproduce cell of their type. That is, while embryonic stem cells can differentiate into any type of cell, adult stem cells can only reproduce cells of their type. If they are muscle cells, they can be used to reproduce only muscle cells. However, recent work has indicated that some adult stem cells may be able to differentiate into other cell types.
Why are we and special groups interested in stem cells?
Because stem cells can differentiate, that is, can be used to reproduce other cell types, they have tremendous potential for solving many human health problems.
Some groups do not want scientist to take human embryos for research in any way whatsoever. Because of this, President Bush restricted stem cell research to existing stem cell sources. Other governments have stayed out of the research arena and stem cells are collected at the whims of the scientist.
Scientists argue that excess stem cells are produced in fertility clinics and that they should be used to benefit mankind.
So, what do you think?
What are the goals of stem cell research?
First, scientists want to understand differentiation. We all know that the human embryo creates all the cell types in the human body. Scientists want to know how and when genes turn on and off to create a particular cell type. Abnormal cell divisions cause birth defects and cancer. Scientists want to know what signals a change in the process of cell development. This could lead to cures for cancer and birth defects.
Stem cells could be used to test new drugs rather than human guinea pigs and animals. Damage to the stem cells would eliminate the drug before it could do damage in the market place, as so many drugs
