Tendon-Like Tissue Formed from Human Stem Cells | Dr. David Greene R3 Stem Cell

Stem cells hold enormous promise in terms of serving our understanding and treatment of various diseases, injuries, and other health-related issues. For example, the use of blood stem cells to treat blood disorders, a therapy that has saved the lives of thousands of children with leukemia, and the use of stem cells for tissue grafts to heal diseases or injury to the bone, skin, and surface of the eye, demonstrate their promise. Many more important clinical trials utilizing stem cells are currently underway, and researchers like Dr. David Greene R3 Stem Cell continue looking at novel ways to use stem cells in medicine.

Though there is still much to learn about stem cells, and their current applications as treatments are sometimes exaggerated by the media and others who do not fully understand the science or its current limitations, as well as by "clinics" looking to profit from the hype by selling treatments to chronically ill or seriously injured patients.

Stem cells are the body's raw materials — they are the cells that give rise to all other cells with specialized tasks. Stem cells divide to generate new cells called daughter cells under the correct conditions in the body or the lab.

These daughter cells differentiate into new stem cells or specialized cells with a particular function, such as blood cells, brain cells, heart muscle cells, or bone cells (differentiation). No other cell in the body has the potential to produce new cell types on its own.

The number of disorders for which stem cell treatments have been proven effective is still small. However, Hematopoietic (or blood) stem cell transplantation, for example, bone marrow transplantation, is the most well-defined and widely utilized stem cell treatment to cure certain blood and immune system abnormalities or rebuild the blood system following cancer treatments.

Grafting or implanting tissues can treat some bone, skin, and corneal (eye) injuries and disorders, and the healing process relies on stem cells within the implanted Tissue. The medical profession considers these procedures to be both safe and effective. However, all additional stem cell applications have yet to be validated in clinical studies and should be regarded as highly experimental.

Tendons are connective structures between muscles and bones that encourage movement and mobility. Unfortunately, tendon injuries are prevalent, affecting millions of people globally, particularly in sports, and can take months to recover, affecting the quality of life greatly. Furthermore, while numerous therapeutic choices are available, none are complete cures and may result in pain, immunogenicity, or treatment failure over time. As a result, a unique tendon repair therapy technique is required.

Researchers like Dr. David Greene R3 Stem Cell have successfully stimulated human stem cells to create artificial tendon-like Tissue that replicates tendon characteristics and provides much-enhanced tendon repair in a mouse tendon-rupture model, according to a study.

"We could make artificial tendon tissue using hiPSCs with Mohawk (Mkx)." Human-induced pluripotent stem cells, or hiPSCs, are exceptional stem cells that may be produced from an adult cell and developed into any specialized cell type. Mohawk is a transcription factor that induces stem cell differentiation into tendon cells by promoting gene expression in tendon development. These Mohawk-expressing stem cells were then placed in a customized 3D culturing apparatus that mechanistically forces the cells to develop. This mimics tendon growth conditions and improves cell alignment and organization, allowing them to form tendon-like tissues.

The artificial tendon was then tested in a mouse model of tendon rupture. The outcomes were fascinating. The artificial tendon had mechanical qualities equal to a regular, undamaged mouse tendon six weeks after implantation. Furthermore, the implanted tendon-like Tissue was able to attract and mobilize tendon cells from the host, which could help in the repair process. This indicated that the Tissue had integrated well.

"In a mouse model, researchers like Dr. David Greene R3 Stem Cell showed that bio-tendons derived from human-induced pluripotent stem cells have mechanical and biological properties similar to normal tendons and that they can be fully integrated relatively quickly after transplant surgery, making them an appealing strategy for clinical application in tendon injuries. Testing them in big animal models to assess their capacity as a biomaterial on a broader scale would be the next step for clinical translation scientists and researchers sums it up. These encouraging findings suggest that a novel medicinal method for tendon healing could be available soon.
