Stem Cells Derived from Tissues Normally Discarded After Surgery

Researchers at the University of São Paulo in Brazil have determined that discarded fallopian tubes, removed during hysterectomy (removal of the uterus) or female sterilization procedures, may be an excellent source of stem cells.

In their study of discarded fallopian tubes, the researchers determined that immature stem cells collected from the tissues could differentiate into a variety of different body tissues. After harvesting the stem cells, the scientists were able to multiply the cell lines and make the stem cells develop into bone, cartilage, fat, and muscle cell lines.

Using human tissues such as fallopian tubes removed during surgeries which would otherwise be discarded provides a welcome alternative to the ethical dilemma related to the use of embryonic stem cells. Further research will be necessary before stem cells derived from discarded human tissue can be used in human medical treatments.

The results of the scientists’ research was published in the June 18 edition of the Journal of Translational Medicine. Scientists who contributed to the research include Tatiana Jazedje, Paulo M. Perin, Carlos E. Czeresnia, Mariangela Maluf, Silvio Halpern, Mariane Secco, Daniela F Bueno, Natassia M. Vieira, Eder Zucconi, and Mayana Zatz.
