 Growing Teeth with Stem Cells                       (a.k.a. Taking a Bite Out of Implants)

Posted by taylor@stemsave.com on Mar 14, 2018 12:00:00 PM

Researchers at Tufts University School of Dental Medicine are creating bioengineered teeth from dental stem cells, with the ultimate goal of replacing dental implants. The innovative approach utilizes a hydrogel that has been developed to encapsulate dental stem cells enabling them to differentiate and grow into buds that can be implanted to grow into healthy teeth. In a pre-clinical model, the procedure involves using the hydrogel to provide a scaffold for the stem cells to grow in vitro, followed by the implantation of the scaffold in vivo, where the stem cells developed into whole tooth structures.

Treating Muscular Dystrophy with Stem Cells

Posted by taylor@stemsave.com on Dec 13, 2017 4:45:00 PM

UCLA researchers have developed a potential stem cell based treatment for Duchenne Muscular Dystrophy (DMD). This degenerative muscular disorder - caused by a genetic mutation in a protein essential for skeletal muscle function - primarily affects young men and boys, degenerating skeletal muscle to the point where it eventually wastes away. This severe degeneration of skeletal muscle results in almost a complete lack of voluntary movement. The UCLA team used the gene editing technology, CRISPR, to repair the mutated gene for the protein in stem cells obtained from the subjects and reintroduced the re-programmed muscle cells back into the subjects. In an animal model, the re-programmed cells successfully produced the dystrophin protein, reversing the degeneration of the skeletal muscle. The team has also conducted a second set of biological markers to ensure complete differentiation into adult muscle cells.

Stem Cells Reverse MS in Breakthrough Clinical Trial

Posted by taylor@stemsave.com on Dec 1, 2017 12:30:00 PM

A team of researchers at the Hadassah Medical Center in Israel has developed a unique method of applying a patient’s own stem cells to restore mobility following progressive multiple sclerosis (MS). MS is an autoimmune disorder in which the body attacks its own neurons and affects millions of people worldwide. Severely progressive MS leads to complete loss of limb function, memory problems, seizures, and even systemic organ failure. This groundbreaking, double-blind, Phase II clinical trial successfully administered autologous (the patient’s own) mesenchymal stem cells, which were cultured and expanded to clinically significant numbers, and then applied directly into the spinal fluid. The treatment simultaneously addressed the two problems of MS - inflammatory immune response and the destruction of the outer coating of neurons that allows for quick signal transduction thereby engendering a significant increase in efficacy.

Stem Cell Wound Treatment Enters Phase II Clinical Trials

Posted by taylor@stemsave.com on Oct 19, 2017 5:00:00 PM

Sanford Health is heading into the second phase of clinical trials involving autologous (the patient’s own) stem cells to treat non-healing wounds and ulcers on the body. The trial will be recruiting patients 18 and older to continue testing the efficacy of stem cells in treating wounds that would not heal due to a person’s preexisting conditions. People with weakened immune systems could also benefit from this treatment, given that it would prevent the enormous risk of infection that non-healing wounds pose. Additionally, the treatment could even be applied to heal wounds from surgeries, expediting recovery time dramatically.

Dental Stem Cells for Bone Regeneration - Clinical Trial Underway

Posted by taylor@stemsave.com on Oct 10, 2017 4:45:00 PM

The team at Central Hospital in Nancy, France is conducting research utilizing dental stem cells to regrow and restore bone density. The trial aims to direct dental mesenchymal stem cells to differentiate into engineered osteoblasts, as well as promoting angiogenesis, which is necessary given that bones typically lack sufficient vascularization to make efficient repairs. The benefit of using autologous [the patient’s own] stem cells makes this an effective treatment option that does not pose a risk of rejection. By directing stem cells to promote bone mineralization and endothelial growth, as well as creating vascularization to promote healing, stem cells can be applied to a variety of bone trauma and deficiencies.

Bone-afide Stem Cells

Posted by taylor@stemsave.com on Sep 29, 2017 4:45:00 PM

Researchers at University of Glasgow have developed a new “nanokicking” technology, which directs mesenchymal stem cells to precisely differentiate into a bone material for use in fracture repairs and bone grafting. By subjecting the stem cells to ‘nanokicking’ – precise, nanoscale vibrations, while the cells are in a collagen gel, these cells can more effectively transform into bone cells capable of replenishing damaged or depleted bone mass. Current bone grafts obtained from patients themselves nearly never yield enough bone material to be clinically relevant for severe injuries, and donor bone grafts have a high risk of rejection hence, autologous stem cell grafts represent an optimal treatment option for patients suffering from any type of bone trauma or deficiency. With bone being the second most grafted tissue [behind blood], ‘nanokicking’ the patient’s own stem cells would significantly impact patient outcomes following reconstructive, maxillofacial and orthopedic surgeries.

Eradicating Leukemia with Stem Cells

Posted by taylor@stemsave.com on Aug 14, 2017 5:00:00 PM

A fourteen-year-old cancer patient has gone into full remission after partaking in the clinical trial of a stem cell therapy conducted at the Children’s Hospital of Philadelphia. The recently approved FDA treatment, also known as chimeric antigen receptor T-cell [CAR T cell] therapy, works by obtaining autologous (the patient’s own) immune stem cells, genetically altering and expanding them to recognize a specific molecule on the surface of cancer cells and become targeted cancer killers. In this case, it was used to treat acute lymphocytic leukemia (ALL) originating in the B cells.

Treating a Devastating Skin Disorder with Stem Cells

Posted by taylor@stemsave.com on Jul 6, 2017 1:45:00 PM

Researchers at the University of Minnesota, world leaders in the treatment of Epidermolysis Bullosa (EB), have developed a stem cell treatment [utilizing mesenchymal stem cells – MSCs] to treat the disorder. This devastating condition involves problems with connective tissue, making skin blister and tear with the slightest contact; severe cases impact internal organ tissues as well. Affecting 1 in every 20,000 children, the disorder can lead to severe infections and be fatal. The team at the University utilized a treatment involving complete renewal of the immune system through chemotherapy and a bone marrow transplant, followed by the administration of mesenchymal stem cells to regenerate the skin tissue.

Texas Legislators Give Boost to Stem Cell Treatments

Posted by taylor@stemsave.com on Jun 22, 2017 1:00:00 PM

The Texas legislature has just passed House Bill 810, allowing chronically or terminally ill patients access to adult stem cell treatments that are currently in clinical trials but are not yet approved by the FDA. Hence, potentially successful treatments may now be accessed by patients who have exhausted all other measures of treatment, but whose time will have run out by the time these treatments receive approval.

Premature Babies Build Lungs with Stem Cells

Posted by taylor@stemsave.com on Jun 6, 2017 1:30:00 PM

Dr. Bernard Thébaud at the Ottawa Hospital in Canada has been researching the application of mesenchymal stem cells to treat bronchopulmonary dysplasia, a disorder found in nearly half of the infants born before 28 weeks’ gestation. Given that the lungs are the last organs to develop, premature babies suffer from a variety of respiratory ailments, and this deficiency leads to problems with the brain and eyesight as well. Showing promising results in reduction of inflammation and tissue repair in mice subjects, Dr. Thébaud's team has been given a grant to begin clinical trials with 10 to 15 prematurely born patients. The trials are expected to commence within the next two years.
