Current Advanced Therapies Based on Human Mesenchymal Stem Cells

The most commonly applied in the treatment of joint, disk, and spinal injuries are the bone marrow-derived and fat cell or adipose-derived stem cells collected by bone marrow extraction and a mini-liposuction respectively. These collection procedures usually take around 15 minutes and are performed in a sterile environment. Platelet-rich plasma is also collected from the patient’s blood, which is a concentrated mix of serum and platelet.
It was also confirmed that EPO could inhibit MSC migration under oxidative stress and stimulate MSC regeneration through local accumulation . Yi et al. obtained transgenic rabbit BMSCs by transfection with a recombinant adenovirus vector carrying human metalloproteinase tissue inhibitor -1, and implanted them into the rabbit IDD model. Compared with the normal BMSC transplantation group, the degree of IDD in the TBT group was significantly improved, the content of ECM was significantly increased, and the hTIMP-1 mRNA and protein expression levels were higher than those in the stem cell normal group. Experiments in vivo also indirectly reflected the fact that cell transplantation in combination with loaded genes or drugs may have better therapeutic effects . BMSCs are non-hematopoietic stem cells in the bone marrow that possess self-renewal ability, multiple differentiation potential, and certain homing ability, and can enhance the survival and regeneration of IVD cells and prevent further deterioration of IDD . BMSCs can repair degenerated IVD tissues by promoting cell proliferation and enhancing production of COL I, proteoglycans, and other ECM components.

Regenera Activa and hair transplant surgery are established treatments for hair loss, each with its own approach and benefits. Regenera Active involves the extraction and implantation of progenitor cells, whereas hair transplant surgery extracts and implants hair follicles. Furthermore, the autologous micro-grafts and injection sites are hardly detectable with a Regenera Activa treatment, versus a hair transplant which requires shaving of the donor area, with the follicular implants obviously visible. Regenera Activa is a clinically proven treatment option for hair thinning and hair loss on the scalp.
This genetic machinery can be turned off with stem cell treatment and halt the progressive damage to the joint surface. At six months from arthroscopic rotator cuff repair, the stem cell treated group had 100% of the cuffs intact on ultrasonic evaluation compared to only 67% of the non-­stem cell group. At 10 years, 87% of the stem cell treated cuffs were intact, compared to only 44% in the non treated group. By adding growth factors to the stem cell injection, your older stem cells will behave more like juvenile stem cells and remain active for longer periods of time. We now have the technology to use your own stem cells to heal many common orthopedic problems faster and better than surgery. With a single treatment we have a better than 80% success rate with problems such as Osteoarthritis of the knee or hip (even bone-on-bone), Rotator cuff, chronic back pain, sports injuries and many other conditions.
Apart from decellularized meniscus matrix scaffolds, other natural source-based scaffolds have also been explored. Ying et al. designed and fabricated a porous silk fibroin scaffold and used it to load BMSCs to repair meniscus injury in rabbits. The porous structure of the scaffold benefits BMSCs adhesion and proliferation as well as facilitates meniscus regeneration. 6 and 12 weeks after implantation, significant positive glycosaminoglycan , collagen I, collagen II, and S100 protein staining were observed around arranged fibrous cartilage-like neo-tissue in the defect area in the experimental group. Hu et al. fabricated a novel sliver nanoparticle using Bauhinia acuminate plant flower extract. The silver nanoparticle can promote the proliferation and osteogenic differentiation of BMSCs as well as accelerate the healing process of the meniscus, which was attributed to its outstanding anti-inflammatory, anti-microbial, and cell chemotaxis properties.

Flow chart of the preparation of the A MECM gel, B KGN-containing PLGA microspheres, and C PCL/MECM-KGN µS scaffold; D Possible mechanism of meniscus regeneration. Enhanced mechanical strength, endogenous stem cells, and sustained releasing KGN contributed to meniscus regeneration in these experiments. These treatments are very expensive and primarily promoted via testimonials and online advertising.
Due to the strict monitoring of the clinical application of stem cell therapy, a low limit cell number with effective therapeutic effect needed to be determined in further studies. From another perspective, the modification and conditioned culture that can increase the chondrogenic-differentiation potential and activity of the isolated stem cells may be a promising solution for this problem. For example, the culture medium containing TGF-β is considered to endow the stem cells with extra meniscus-like tissue regeneration ability and promote proteoglycans production and integrative repair after transplantation .

Because of the complexity of stem cell control systems, there is still much to be learned through observations in vitro. For stem cells to become a popular and widely accessible procedure, tumour risk must be assessed. The second problem is to achieve successful immunological tolerance between stem cells and the patient’s body. For now, one of the best ideas is to use the patient’s own cells and devolve them into their pluripotent stage of development.
The injections themselves are shallow and are well away from the main vessels that we normally worry about when doing other injectable treatments such as traditional dermal fillers. "They're important for patients' safety and the protection of the patient in terms of how they're targeted and recruited, and in terms of their expectations of treatment." Warren Williams has chronic back pain, and heard about high profile stem cell doctor Ralph Bright through an ad on commercial radio. With the patient receiving his or her own cells, the process is exempt from the normal regulations governing cell therapy.
Due to this technique, it can become possible to generate healthy heart muscle cells and later transplant them to patients with heart disease. Although pluripotency can occur naturally only in embryonic stem cells, it  is possible to induce terminally differentiated cells to become pluripotent again. The process of direct reprogramming converts differentiated somatic cells into iPSC lines that can form all cell types of an organism. Reprogramming focuses on the expression of oncogenes such as Myc and Klf4 (Kruppel-like factor 4). This process is enhanced by a downregulation of genes promoting genome stability, such as p53. All these processes can cause potential mutagenic risk and later lead to an increased number of mutations.

This study was supported by LiaoNing Revitalization Talents Program , the Science and Technology Innovation Foundation of Dalian and the open project of Key Laboratory for Micro/Nano Technology and System of Liaoning Province, Dalian University of Technology . The funders had no role in the study design, data collection and analysis, decision to publish, or preparation of the manuscript. Because the IVD has no blood vessels, its internal and external material exchanges can only occur through concentration gradients  of these materials.
The CEPs are horizontal hyaline cartilaginous structures that act as important structures for the IVD to carry out substance exchange and information transfer. The ECM is mainly composed of COL II, fibres, elastin, and large amounts of proteoglycans, especially aggrecan , with negative charge . You will need to refrain from taking nonsteroidal, anti-inflammatory medications for a while as this can affect the healing process of your body. Multiple sclerosis is a disease where the body's immune system attacks its own myelin, which is a protective covering for the central nervous system. Verywell Health uses only high-quality sources, including peer-reviewed studies, to support the facts within our articles.

In some cases, patients with tendinopathy may have an increased risk of tendon rupture, especially among those in the older population (Yasui et al., 2017). Nevertheless, acute shoulder trauma may cause partial or complete tendon tears, which require surgical treatment to repair the continuity of the structure or surgery to reattach the tendon back to its bony insertion. Stem cell transplantation using a suitably matched donor is the only potential cure for MDS.
