Is there any success operation from stem cell therapy?

Stem cell treatment has achieved positive results in more than 45% of patients, says trial. Patients saw improvement in less than 6 months, which compares quite well to back surgery which usually involves very long recovery times. The popularity of stem cell treatments has increased significantly, thanks to their high efficacy and recorded success rates of up to 80%. It is a modern type of regenerative medical treatment that uses a unique biological component called stem cells.

The most common applications of this treatment include chronic diseases, musculoskeletal injuries or even heart and lung diseases. New studies are continually emerging that investigate and support the effectiveness of this treatment. These daughter cells become new stem cells or specialized cells (differentiation) with a more specific function, such as blood cells, brain cells, heart muscle cells, or bone cells. No other cell in the body has the natural ability to generate new types of cells.

Stem cells may have the potential to grow into new tissue for use in transplantation 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 the new stem cells. However, scientists do not yet know if the use of altered adult cells will cause adverse effects in humans.

Embryos used in embryonic stem cell research come from eggs that were fertilized in in vitro fertilization clinics, but were never implanted in women's uteri. Stem cells are donated with the informed consent of donors. Stem cells can live and grow in special solutions in test tubes or petri dishes in laboratories. Although research on adult stem cells holds promise, adult stem cells may not be as versatile and long-lasting as embryonic stem cells.

Adult stem cells may not be manipulated to produce all types of cells, limiting how adult stem cells can be used to treat diseases. Adult stem cells are also more likely to contain abnormalities due to environmental hazards, such as toxins, or errors acquired by cells during replication. However, researchers have found that adult stem cells are more adaptable than originally thought. Stem cell therapy, also known as regenerative medicine, promotes the reparative response of diseased, dysfunctional or injured tissues through the use of stem cells or their derivatives.

It is the next chapter in organ transplantation and uses cells instead of donor organs, which have a limited supply. Doctors have performed stem cell transplants, also known as bone marrow transplants. In stem cell transplants, stem cells replace cells damaged by chemotherapy or disease, or serve as a way for the donor's immune system to fight some types of cancer and blood-related diseases, such as leukemia, lymphoma, neuroblastoma, and multiple myeloma. These transplants use adult stem cells or cord blood.

Embryonic stem cells can also trigger an immune response in which the recipient's body attacks stem cells as foreign invaders, or stem cells can simply stop working as expected, with unknown consequences. Researchers continue to study how to avoid these possible complications. Therapeutic cloning, also called somatic cell nuclear transfer, is a technique 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 removed from a donor cell. This donor nucleus is then injected into the egg, replacing 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 donor cells, essentially a clone. Some researchers believe that stem cells derived from therapeutic cloning may offer benefits over those of fertilized eggs because cloned cells are less likely to be rejected once transplanted back to the donor and may allow researchers to see exactly how a cell develops. disease. Researchers have not been able to successfully perform therapeutic cloning with humans despite success in other species.

Researchers hope that stem cells will one day be effective in treating many medical conditions and diseases. However, treatments with unproven stem cells can be unsafe, so be aware of all the facts if you are considering treatment. For new drug testing to be accurate, cells must be programmed to acquire the properties of the drug's target cell type. In cases where stem cells have been administered to the eye, blindness has been reported and when they have been administered to the central nervous system by lumbar puncture (spinal tap), adverse outcomes have occurred including severe central nervous system infections and tumors.

The Japanese team found that injecting stem cells isolated from patients' bone marrow helped to regain lost sensation and mobility. The list of diseases for which stem cell treatments have been shown to be beneficial is still very short. All other applications of stem cells have not yet been demonstrated in clinical trials and should be considered highly experimental. In addition, significant improvement in eyesight was reported for patients suffering from macular degeneration following transplantation of induced pluripotent stem cells (iPSC) derived from patients who were induced to differentiate into retinal pigment epithelial cells (.

The use of iPSC in therapy is still considered a high-risk treatment modality, since transplantation of these cells could induce tumor formation. These trials revolve around the engraftment of insulin-producing beta cells into a subcutaneous encapsulation device to protect cells from autoimmunity in patients with type 1 diabetes (40). It is true that these cells symbolize a paradigm shift, as they allow researchers to directly observe and treat relevant patients' cells; however, a number of challenges still need to be addressed before cells derived from iPSCs can be applied in cell therapies. They allow the body's natural therapeutic capacity to regenerate and produce new, healthy cells that will replace diseased or injured cells.

However, it should be noted that evaluating stem cell-based therapies is not an easy task, as cell transplantation is ectopic and can lead to tumor formation and other complications. Stem cells have been successfully isolated from human teeth and studied to test their ability to regenerate dental structures and periodontal tissues. Researchers have discovered ways to target stem cells to become specific types of cells, such as causing embryonic stem cells to become cardiac cells. In addition to fat cells, some clinics give bone marrow stem cells or stem cells from the umbilical cord or placenta, which come from unrelated donors.
