The success rate of stem cell therapy varies depending on the condition being treated, but recent studies have shown promising results. For example, in treating certain types of blood cancer, stem cell transplants have a success rate of 60 to 70%. In regenerative medicine, stem cell therapy for joint repair. Autoimmune or inflammatory diseases have recorded success rates of around 80%.
Stem cells are a special type of cell that have two important properties. They can produce more cells like yours. And they can turn into other cells that do different things in a process known as differentiation. Stem cells are found in nearly every tissue in the body. And they are necessary for tissue maintenance, as well as for repair after injury.
No other cell in the body has the natural capacity to generate new types of cells. People who may benefit from stem cell therapy include those with leukemia, Hodgkin's disease, non-Hodgkin lymphoma, and some types of solid tumor cancer. Stem cell therapies may also benefit people who have aplastic anemia, immunodeficiencies, and inherited metabolic conditions. Stem cells may have the potential to grow into new tissue for use in transplants and regenerative medicine.
Researchers continue to advance knowledge about stem cells and their applications in regenerative and transplant medicine. This new technique may allow the use of reprogrammed cells instead of embryonic stem cells and prevent the immune system from rejecting new stem cells. However, scientists do not yet know if using altered adult cells will cause adverse effects. in human beings.
The embryos used in embryonic stem cell research come from eggs that were fertilized in in vitro fertilization clinics, but that were never implanted in women's wombs. Stem cells are donated with the informed consent of the donors. Stem cells can live and grow in special solutions in test tubes or petri dishes in laboratories. While adult stem cell research is promising, adult stem cells may not be as versatile and durable as embryonic stem cells.
Adult stem cells may not be manipulated to produce all types of cells, limiting the way adult stem cells can be used to treat diseases. Stem cell therapy, also known as regenerative medicine, promotes the repair response of diseased, dysfunctional, or injured tissue through the use of stem cells or their derivatives. It's the next chapter in organ transplantation and uses cells instead of donor organs, whose supply is limited. Doctors have performed stem cell transplants, also known as bone marrow transplants, for many decades.
In hematopoietic stem cell transplants, stem cells replace cells damaged by chemotherapy or disease, or serve to help the donor's immune system fight certain types of cancer and blood-related diseases. Leukemia, lymphoma, neuroblastoma, and multiple myeloma are often treated this way. These transplants use adult stem cells or umbilical cord blood. Embryonic stem cells can also trigger an immune response in which the recipient's body attacks stem cells as foreign invaders or, simply, the stem cells can stop working as expected, with unknown consequences.
Researchers are still studying how to avoid these potential complications. Therapeutic cloning, also called somatic cell nuclear transfer, is a way to create versatile stem cells independent of fertilized eggs. In this technique, the nucleus of an unfertilized egg is removed. This nucleus contains the genetic material.
The nucleus is also extracted from a donor cell. This donor nucleus is then injected into the egg to replace the nucleus that was removed, in a process called nuclear transfer. The egg is allowed to divide and soon forms a blastocyst. This process creates a stem cell line that is genetically identical to the donor's cells, in essence, a clone.
Some researchers believe that stem cells derived from therapeutic cloning may offer benefits compared to those from fertilized eggs because cloned cells are less likely to be rejected once transplanted back to the donor. And it can allow researchers to see exactly how a disease develops. Researchers have not been able to successfully perform therapeutic cloning in humans, despite the success achieved in other species. Mayo Clinic does not endorse companies or products.

Stem cell therapy was developed only a few decades ago, but it has demonstrated remarkable success in treating orthopedic injuries. Stem cell-based therapies for all other conditions are still experimental.
The ClinicalTrials, gov website contains the most up-to-date information on clinical trials testing whether stem cell-based therapies are safe and effective in humans. These stem cells are manipulated to specialize in specific types of cells, such as heart muscle cells, blood cells, or nerve cells. If you're a cell biologist, that's the grail, says Jeanne Loring, professor emeritus at the Scripps Research Institute and co-founder of Aspen Neuroscience, a company that plans to treat Parkinson's disease with a dopamine-producing cell transplant. Stem cells, in particular those derived from human umbilical cord stem cells (HUCMSCs), are effective and safe for treating severe COVID-19, and have demonstrated their potential in more than 100 international clinical trials140. Stem cells play a role in suppressing acute phase responses by suppressing excessive activation of macrophages and T cells and initiating the secretion of inflammatory cytokines.
In orthopedic care, stem cells act as a repair mechanism that works against tears, breaks, and other injuries. In preclinical animal models, stem cells modified to express different cytotoxic chemicals steadily reduced tumor size and increased survival153 154. Within the ASC class, hematopoietic stem cells are a specific subset essential for bone marrow transplantation44. Explore the transformative potential of stem cells in the treatment of traumatic brain injury (TBI) and provide information about their role in neurogenesis, neuroprotection and brain repair. However, the larger picture of stem cell therapy, including the use of several types of stem cells, is still developing. This review describes the advances and challenges for the development of stem cell-based therapies, focusing on the use of stem cells in dentistry, in addition to the advances achieved in regenerative treatment modalities in several diseases. A transcription factor known as NF-B controls the diverse functions of NF-b in stem cells and development processes97. Harnessing the potential of stem cells to regenerate is the primary goal of research, particularly in HSCs, to transplant bone marrow and explore their role in immune cell therapies to combat various blood-related ailments 188. That November, James Thomson, from the University of Wisconsin, reported that he had captured stem cells from five embryos and that these cells were alive and multiplying in his laboratory.
This could be the first cell therapy for epilepsy, says Kriegstein, a professor at the University of California, San Francisco, who is also an advisor to Neurona and its co-founder.
