Frequently Asked Questions on Stem Cells
What are autologous adult regenerative cells?
Autologous adult regenerative cells are unique and fascinating types of cells that are part of every multi-cellular organism. They were discovered more than 40 years ago when researchers found that cells derived from bone marrow possessed the unique ability to form various adult tissues. Under the right conditions adult regenerative cells are capable of developing into other specialized types of cells through a process that aids in the regeneration of damaged tissues and organs.
Where do regenerative cells come from?
In adults, regenerative cells are present within various tissues and organ systems, the most common being bone marrow and fat tissues. Other sources include the liver, epidermis, retina, skeletal muscle, intestine, brain, placenta, umbilical cord and dental pulp.
How are stem cells obtained and prepared?
One of the richest sources of adult stem cells is bone marrow, and the hip (pelvis) is one of the best and easiest locations for obtaining bone marrow. In the harvesting procedure the doctor typically removes (aspirates) from the patient’s pelvis. A trained nurse or technician then uses specifically designed equipment to concentrate the stem cells in the bone marrow and provides the cells back to the surgeon for implantation at the site of injury.
Will my body reject the stem cells?
No, since they are collected from your own tissue they do not represent an immunogenic threat. In addition, the possibility of disease transmission from the use of donor material is avoided.
What are the differences between adult stem cells and embryonic cells?
Unlike embryonic cells, adult stem cells are obtained from the patient’s own tissue and therefore do not present any ethical issues with regards to their use in treating human disease. Autologous adult stem cells have been used by clinicians for decades to treat a variety of conditions.
