With the ability to become virtually any cell in the body, ES cells captured the popular imagination as a powerful tool to battle neurodegenerative diseases like Parkinson’s disease. The development was heralded by some as the means to one day curing the most intractable degenerative diseases - at the same time it also triggered a robust social debate about the destruction of a human embryo. With a steady supply of mouse ES cells, scientists could study development and disease.Īnother breakthrough came in 1998 when James Thomson at the University of Wisconsin-Madison employed a similar technique to grow human ES cells in the lab. In effect, he described adult stem cells which renew themselves and serve as a means to repair and maintain tissues like the breast, brain, and bone marrow.įor the next 70 years, scientists made progress in understanding how stem cells worked, but they couldn’t fully study them until 1981 when Gail Martin at the University of California, San Francisco and Martin Evans at the University of Cambridge plucked a cell from a mouse embryo and coaxed it to grow in a petri dish. Russian biologist Alexander Maximow theorized in 1909 that a set of “stem cells” in bone marrow could differentiate into red and white blood cells. Boveri’s description comprises the essential characteristics of an embryonic stem (ES) cell. Twenty years later, fellow German Theodor Boveri refined that term to describe roundworm embryo cells capable of making copies of themselves (self-renewal) and specializing (differentiating) into any other cell. In 1868, German biologist Ernst Haeckel coined the term “ stem cell” to describe a fertilized egg. Ever since, scientists have been trying to understand how a single cell could contain and direct such unlimited potential. A Cell With Unlimited PotentialĪfter nearly 200 years of peering through ever more powerful microscopes, scientists in the mid-19th century pieced together the implications of what they saw: cells were the building blocks of all life, and the human body developed from a single cell - a fertilized egg. An “induced” stem cell, created from an existing cell, harnesses that flexibility and offers the opportunity to study and perhaps develop new treatments for neurological diseases. A stem cell retains that potential and when prodded correctly can become anything from a heart cell to a brain cell. It can also disqualify you from participation in a registered clinical trial.Every person starts life as a single cell with unlimited potential. Undergoing an unproven stem cell treatment may interfere with proven and potentially beneficial therapies or treatment plans recommended by your general practitioner or specialist. Unproven stem cell treatments may also involve significant financial costs, including treatment and follow-up costs, as well as the cost of emergency medical care in the event that something goes wrong. The risks include infection and growth of specialised tissue in the wrong place (ectopic tissue formation). However, an unproven autologous stem cell treatment may be unsafe, posing serious risks to your health. As the cells come from the same person, there is a lower chance of reaction and rejection of the cells by the patient's immune system. These cells may be treated, processed or purified after removal. Where one or more criteria are not met, including advertising to consumers, regulation by TGA will apply.Īre there any approved facilities for storing stem cells in Australia?Īutologous cells are those that are removed from and applied to the same person. manufactured by that medical or dental practitioner, or by a person or persons under the professional supervision of that medical or dental practitioner in a hospital (except storage and testing), for that patient who must be a patient of that hospital.collected from a patient who is under the clinical care of a medical or dental practitioner registered under a law of a State or an internal Territory.Under this provision stem cell treatments may not be subject to regulation by TGA if they meet all of the following criteria: Some products that would otherwise be considered biologicals are excluded from TGA regulation (through the Therapeutic Goods (Excluded Goods) Determination 2018). However, the TGA does not regulate medical practice. This includes human stem cell treatments. In Australia, the Therapeutic Goods Administration (TGA) is responsible for the regulation of products for therapeutic use including human cells and tissues (termed 'biologicals').
