Stem Cell Therapy as Major Advancement in Medical Realm
Due to the emerging and re-emerging of different diseases, stem cell research has offered new and more efficient ways of curing diseases. Stem cell research has great contribution in medical advancement although its potential is not fully expressed in humans. Traditional medical procedures combined with numerous researches on stem cells has given scientists and medical practitioners an improved and more advanced option to treat patients with cardiovascular diseases, brain diseases, blood diseases as well as to regenerate organs and tissues.

Stem cells are immature unspecialized cells that are capable of dividing continuously to give rise to specialized cell types. These can be manipulated to create specialized tissues that could be used to treat damaged cells, tissues or organs. Stem cell can be classified by its ability to differentiate into various cell types: totipotent which can generate all the cells and tissues that make up an embryo, pluripotent that has potential to become almost all of tissues in embryo except supporting cells and tissues and lastly, multipotent which is capable of giving rise to cells with particular function. These are either embryonic or adult stem cells. Embryonic stem cells can be isolated from three-to-five day old embryo while the adult stem cells can be derived from brain, muscle, bone marrow, where stem cells are most abundant and others (Ness, 2004).
Scientists have gone long way to validate stem cells’ effectiveness through different researches and interventions. However, most of these interventions are tested first in animals before in humans to ensure safety.
Researchers from Massachusetts General Hospital were able to create blood vessels in laboratory mice through human stem cells as reported in PNAS Early Edition issued last July 2013. The newly formed blood vessel were as good as the natural one and lasted for 280 days.
