Bone Regeneration Made Possible With Stem Cells

Epibone creates precisely measured scaffolding for stem cells to recreate damaged bone.

The New York-based startup Epibone intends to begin human testing on a procedure that will utilize stem cells to regenerate living bone tissue.  The researchers, originally from Columbia University, will apply autologous [the patient’s own] stem cells to nanofiber scaffolding of the desired size and shape and direct the stem cells to differentiate into a physical and genetic replica of the patient’s own bone.

Gel-Like Polymers May Improve Stem Cell-Based Therapies.

Scientists are developing a polymeric gel to protect stem cells from trauma during transplant injections.

Complex chemical polymers are currently being developed by scientists at Stanford University to protect and support the proliferation of stem cells during spinal cord transplantation procedures.  The gels are designed to provide padding for the cells during injection, while also varying in viscosity and the biochemical signals contained within to offer stem cells an optimal environment for differentiation.

Osteoarthritis Stem Cell Treatment in Clinical Trial

The transplantation of stem cells into areas affected by osteoarthritis allow lost cartilage tissue to regenerate.

In recent clinical trials, researchers at the National University of Ireland Galway have successfully utilized adult stem cells to treat patients with osteoarthritis.  The treatment involves recovering the patients’ own [autologous] stem cells and then injecting the stem cells into cartilage to stimulate the regeneration of lost tissue.

Stem Cells Make a Dentin Tooth Decay.

Researchers have utilized low-intensity lasers to regenerate lost dentin in damaged teeth.

Researchers at the National Institute for Dental and Craniofacial Research have developed a method of utilizing autologous [the patient’s own] dental stem cells to regenerate damaged or decayed teeth.  In an animal model, as well as human cells in vitro [in a lab], the scientists treated the damaged teeth with low-intensity lasers, which prompted the stem cells located in the dental pulp to differentiate and grow into new, healthy dentin tissue.

Treating Arthritis with Stem Cells

damaged knee and mesenchymal stem cells

Arthritis affects 44 million individuals in the US resulting in the need for approximately 700,000 knee-replacement and 100,000 hip replacement surgeries every year. Researchers at Stanford University have developed a technique to track the effectiveness of mesenchymal stem cells [the type of stem cells found in teeth] in repairing arthritic joints. Mesenchymal stem cells are capable of differentiating into bone and cartilage, as well as muscle, fat and tendon.  The researchers expect to adapt the study for clinical trials in humans this fall.
