Stem cells are being used currently for medical treatments. Look at bone marrow transplants that are used to treat leukemia utilizing adult stem cells. Scientists are actively looking at stem cells to treat diseases such as cancer, Parkinson's disease, and spinal cord injuries.
There are actually many publicly traded companies involved in stem cell research. WallStreetNewsNetwork.com has turned up over 20 stem cell stocks, half of which are currently profitable.
For example, Aastrom Biosciences Inc. is involved in the development of patient-specific products for the repair or regeneration of human tissues, using its own proprietary adult stem cell technology. Because it is a development stage company, the earning have been negative, and the price/sales ratio has been very high (over 250). It currently sells for 2.25 per share and the symbol is ASTM.
StemCells Inc. is involved in the development of stem cell therapeutics to treat damage to or degeneration of major organ systems such as the central nervous system, liver and pancreas. This company also has negative earnings and very low revenues. It sell for about 3.90 per share and the stock symbol is STEM.
Other stem cell stocks can be found at the StemCellsStocks.com website.
As always, I am not recommending these stocks as a buy, hold , sell, or short. Just providing general information on them.
