Tipping the Scales: Stem Cells May Help Prevent Obesity and More.

Scientists have found that the alteration of stem cell cilia can have a positive effect on weight loss.

 

In a recently published study from the Queen Mary University of London, scientists discovered a connection between the length of cilia [hair-like projections for cell movement] on stem cells and their proclivity towards differentiating into fat cells.  By restricting the elongation of stem cell cilia, the researchers were able to impede on the formation of new fat cells.

Male Infertility Research Identifies Sperm-Producing Stem Cells.

A new method of identifying sperm-producing stem cells could lead to stem cell treatments for male sterility.

In a recent study conducted by the University Of Texas Southwestern Medical Center, scientists have discovered a rare line of stem cells involved in regulating spermatogenesis [the production of sperm cells].  Furthermore, these stem cells are resistant to chemotherapy and radiotherapy, which are toxic to the male germline and common causes for male infertility.

Acute Stroke Treatment Utilizing the Patient’s Own Stem Cells

Autologous stem cell therapy has shown significant signs of recovery in acute stroke patients.

In a pilot study conducted by the Imperial College Healthcare NHS Trust, five patients received transplants of their own [autologous] stem cells directly into their brains only seven days after a severe stroke. Although the trial was designed primarily to assess the safety of such a procedure, the patients showed significant signs of recovery considering the typical lethality of the strokes.

Of Mice and Men: Human Stem Cells Utilized in Animal Model Treatment of MS Symptoms

Advancements in a breakthrough stem cell study may provide new treatment options for MS patients.

A team of researchers led by Professor Jeanne Loring of the Scripps Research Institute have advanced a potential treatment option for autoimmune diseases similar to multiple sclerosis by utilizing human stem cells to reregulate the immune system. In an animal model paralyzed by MS symptoms, the scientists differentiated human stem cells into early stage neural cells that, when transplanted into the spinal cords of the compromised mice, secreted proteins that halted the autoimmune attack and enabled the mice to walk and run again.

Leg Injuries Healed With Patient’s Stem Cell Therapy.

A new stem cell therapy allows patients to regrow leg muscle after traumatic injuries.

A research team led by Stephen Badylak at the University of Pittsburgh has used the patient’s own stem cells to help them recover from injuries in which over 50% of their leg muscle was lost. First, they implanted a biological scaffold into the wound.  Then, the patients underwent aggressive physical therapy, which directed the recruitment of stem cells to the site of injury to rebuild properly aligned muscle tissue. By the end of the treatment, patients exhibited muscle regrowth and at least a 20% increase in leg strength. Continue reading

Human Lungs Successfully Grown in Lab via Stem Cells

Scientists may have found a solution for immune rejection of lung transplants.

Researchers from the University of Texas Medical Branch have successfully grown human lungs in vitro [in a lab] by utilizing stem cells.  The team of scientists, led by Dr. Michael Riddle, used a donated lung to engineer a scaffold outlining the lung’s architecture.  Then, they seeded the scaffold with stem cells from the donor’s complementary lung to create a complete, functional, and healthy lung.  Continue reading

Growing Organs With Your Own Stem Cells

A research team led by Doctor Alexander Seifalian at University College London is currently creating custom lab-grown organs and body parts for patients utilizing autologous [the patient’s own] stem cells.  The scientists have engineered a polymer material that they mold into the shape of an organ in need, infuse with the patient’s stem cells, and then transplant back onto the patient’s body.   Continue reading

Dental Stem Cells Fill In For Root Canal Therapy

A new alternative procedure to root canal therapy utilizes stem cells to restore the root canal back to health.

Doctors at the All India Institute of Medical Sciences have developed a novel stem cell therapy called “SealBio” to replace traditional root canal treatments.  SealBio eliminates the need to clean, shape, and fill the tooth with artificial sealer cement by inducing the stem cells of the root to regenerate adult tissue as a natural biological seal. Over time, this technique can even restore the root canal back to health.       Continue reading

Type 1 Diabetes Treatment Utilizes Stem Cells to Regenerate Pancreatic Beta Cells

Stem cells have been differentiated into pancreatic beta cells, providing a potential treatment for Type 1 Diabetes.

Researchers from the Gladstone Institutes have developed a potential treatment for Type 1 diabetes by differentiating stem cells into insulin-producing pancreatic beta cells.  These new cells, when transplanted into animal models, lowered abnormally high glucose levels down to a more healthy level in just one week. Continue reading

Blindness Treatment Utilizes Stem Cells to Partially Restore Vision.

The use of adult stem cells can potentially treat a wide range of visual impairments.

Researchers from the Institute for Ophthalmology at the University College of London report on a significant advancement in stem cell therapy that can potentially lead to new treatments for blindness.  Adult stem cells were manipulated into rod cells and then injected into blind animal models, partially restoring the vision of the animals.  Continue reading
