It has been called the age of stem cells, the seemingly magic root cells of life that can be used to generate almost every other type of cell, possibly opening a door to a new world of regenerative therapy. Hardly a day goes by that some new stem cell development isn't announced, and yet actual treatments involving stem cell technology are still very limited. Much has yet to be learned.

The idea behind stem cells has in fact been around for a very long time. Ever since the invention of the microscope and the development of cell theory, scientists have known that somehow the complex collection of specialized cells that make up the human body have their origin in a single fertilized egg. It was clear that, somewhere during the earliest stages of the developmental process, cells were being systematically transformed into specialized heart cells or nerve cells or liver cells or blood cells. The term "stem cell" was used as early as the late 1800s, before anything was really known about particular stem cells, but, by the early 1900s, it was recognized that different blood cells were all parented by a particular stem cell. By the early 1960s, there was a better understanding of the operation of bone marrow cells and the production of blood cells, which eventually led to today's bone marrow transplants, the transplanting of adult stem cells for the treatment of leukemia and other blood related diseases.

As the technology to grow and work with human cells increased in the late 20th century, human stem cell research took off. Soon the first human embryonic stem cell lines were introduced, which scientists were able to use to fully establish the remarkable abilities of stem cells, suggesting their possible use in generating replacement cells for a broad range of tissues and organs.

Earned a bachelor's degree in physics from the University of Pittsburgh before deciding to switch gears and pursue a career in the financial field. I went on to earn an MBA, also at the University of Pittsburgh. I worked for nearly three decades in the investment business, including nearly two decades with Charles Schwab & Co. While at Schwab, I worked both as a broker and as a trading supervisor. While at Schwab, I wrote the daily pre-market opening update for the entire MidAtlantic region. This task was given to me because of my vast knowledge of and years of experience in researching all markets - stocks, bonds, currencies, commodities and international markets. After leaving Schwab, I became a fulltime investment writer. Currently I am the editor of the paid Growth Stock Advisor newsletter for Investors Alley.
