Do stem cell regulators need regulation?


Twenty percent of people living with Congestive Heart Failure die within twelve months of diagnosis. Research clinics across the nation believe stem cells could offer a solution in the future. Unfortunately, for every research clinic striving for the greater good, there are companies falsely offering cures for financial benefits. These faulty clinics call for extreme regulation in the field of regenerative medicine and, therefore, inhibit stem cell research. The Food and Drug Administration prolong the process of approving regenerative research due to invalid stem cell companies. Though the FDA protects patients with new regulations, the administration also delays the advancements of proper clinical trials. The Food and Drug Administration’s deficiencies prove that regenerative medicine needs a new method of regulation that ensures safety for patients as well as progress in stem cell research.
Regenerative medicine aims to recreate living, functional tissue to repair the human body. Whether fighting a deadly disease, treating a genetic disorder, or combating a painful deformity, regenerative medicine depends on the future of stem cells. These undifferentiated cells hold the ability to mold into nearly any other cell. With mild medical manipulation, scientists hope stem cells will cure many diseases and deformities by replacing the damaged cells. Though regulation for any medical process is necessary, can too much regulation prevent advancement?
In 2010, the Food and Drug Administration won the right to regulate stem cell therapy. Since their legal success, the FDA has only approved one regenerative medicine company, Hemacord. Hemacord provides patients stem cells from umbilical cords, peripheral blood cells, and bone marrow to treat blood related diseases. In other words, the FDA approved bone marrow transplants. Scientists first conducted bone marrow transplants in the 1960’s and have successfully treated diseases such as leukemia since. Will we have to wait nearly fifty years for the FDA to approve every new regenerative procedure?
With the rate that medical science discovers new potential cures, waiting for FDA approval seems counterproductive. Yes, every new process needs regulation to ensure purity and safety, but shouldn’t there be a faster way to regulate new treatments? Science deemed bone marrow transplants effective long before the FDA gave their seal of approval. The FDA claims patients should not undergo any stem cell therapy that does not have approval because the treatments do not exist. Yet, just because a clinical trial does not have FDA approval, as a treatment does not mean the trials are ineffective.
The idea that stem cell therapy acts as a drug gave the FDA the right to regulate regenerative companies. However, the medical community and drug industry continue to argue over whether or not the alteration of stem cells defines the procedures as drugs. The FDA claimed that a stem cell could only have “minimal manipulation” before considered a drug. Unfortunately, “minimal manipulation” lacks a concrete definition. The broad term causes mass amounts of arguments as doctors and scientists perceive minimal manipulation differently than the FDA. Therefore, whose definition do we trust: the FDA or the scientists that created these procedures? The gap of knowledge between medical stem cell specialists and the FDA currently prohibits further regenerative medicine advancements. The FDA should have control only when a sound definition of “minimal manipulation” arises. Until then, clinical stem cell trials should not take the fall for the FDA’s lack of understanding.
This lack of understanding may derive from the Food and Drug Administration’s lack of focus on the positive progress of stem cells. The FDA’s recent media celebrity revolves around their battle to shut down all companies promoting illegal stem cell therapies. These companies target terminally ill patients and offer them untested stem cell treatments with the promise of a cure. One company promised a treatment for an eleven-year-old boy’s cerebral palsy. Tested by Duke University research lab, the stem cells provided to the boy were either defective or dead. Upon further investigation, the doctor providing the stem cells and promoting false treatment lost his license years before moving to Ecuador to sell sham stem cells. Regrettably, many more companies offering similar false treatments remain. These clinics advertise treatments to incurable diseases and claim FDA approval. According to Duke University’s scientific stem cell officer Joanne Kurtzberg, applying defective or dead stem cells into another human can be fatal, causing a stroke or brain inflammation. Therefore, FDA intervention is imperative. However, the FDA does little to differentiate the clinics aiming for economic gains and regenerative companies that intend to cure the world’s largest problems. The negative media coverage of these clinics hinders the reputation of regenerative medicine. With control over stem cell clinics, the FDA should not only abolish faulty companies, but also promote successful procedures as well.
Recently, the Department of Neurosciences of City of Hope discovered a groundbreaking new correlation between stem cells and inoperable brain tumors. Doctors diagnose nearly 23,000 Americans a year with glioblastomas, an extremely aggressive malignant brain tumor. With an average survival rate of 15 months, over half of the patients die soon after diagnosis. Miraculously, City of Hope’s Dr. Karen Aboody provides a clinical trial that strives to treat these once terminal tumors. Before this trial, doctors considered chemotherapy dangerous and ineffective on glioblastomas. Backed by the National Cancer Institute, Aboody’s trial injects chemically manipulated stem cells into a patient’s brain, which then attach to the tumor. The patient then takes a specific drug that reacts with the enzymes in the stem cells, providing an effective form of chemotherapy on the cancer. This trial is far from FDA approval, but has shown positive results thus far. While two patients undergoing treatment lived seven months longer than originally expected, one man still lives today, three years after treatment.

Aboody’s trial targets similar patients as faulty stem cell companies, terminally ill patients with nothing to lose. Furthermore, Aboody’s treatment does not yet have FDA approval and still needs far more testing before considered a proven cure. So, how do patients differentiate between positive trials like the City of Hope’s and falsely advertised stem cell companies? First of all, everyone should heavily research any clinical trial before agreeing to a medical procedure. However, many of these patients hold an unstable emotional state due to their fatal diagnosis and will try anything, regardless of the dangerous side effects. As the FDA works tirelessly to shut down harmful clinics, regenerative medicine needs another form of regulation that encourages the work of pioneering stem cell research.
The field of medicine is growing at a faster rate than ever as scientists seek to find cures for the world’s most troublesome diseases and disorders. Currently, thousands of medical clinics provide trials that offer hope in the future of curing cancer, heart disease, diabetes, genetic disorders, and more. While every medical procedure must be heavily monitored and proven before offered to patients, the field of regenerative field of medicine must create a faster and more successful method of regulation. Until the knowledge gap between scientists and regulators diminishes, the Food and Drug Administration should not hold sole power over stem cell research. The regenerative medical field encompasses the potential to attain great accomplishments through stem cell research. In a generation plagued by cancers and incurable disease, do we have time to delay prospective solutions?
