Recently, one study solely injected BMSC-EVs into the vein to promote rotator cuff repair (Huang et al., 2020). However, it seemed that the effect augmented with BMSCs dissipated by 4 weeks (Degen et al., 2016). The rotator cuff is a critical structure within the shoulder that provides stability and strength to the joint. By using a 405 nm blue light source at a distance, the carrier is converted to the gel state by irradiation for 10–20 s. After delivering TPSC-EVs, tendon repair is promoted by suppressing inflammation and apoptosis and regulating ECM balance (Zhang et al., 2020b). Rotator cuff tears (Fig. Watts, A. E., Millar, N. L., Platt, J., Kitson, S. M., Akbar, M., Rech, R., et al. In this review, we summarize the advances of stem cells and stem cell-derived EVs in rotator cuff repair and highlight the underlying mechanism of stem cells and stem cell-derived EVs and biomaterial delivery systems. Cai, C., Wang, W., Liang, J., Li, Y., Lu, M., Cui, W., et al.
Rodeo, MD, HSS Sports Medicine Institute, Hospital for Special Surgery and Weill Medical College of Cornell University, New York, NY, USA, evaluate the basic science and clinical evidence for the most commonly used biologic agents for treating common shoulder pathologies such as rotator cuff tears, shoulder OA, and tendinopathy. 1177/0363546520908847. If you live in the Denver, Vail and Aspen, Colorado communities and would like additional resources on stem cell therapy for the shoulder, or would like to determine if you are an ideal candidate for this alternative to shoulder replacement, please contact the orthopedic office of Dr. Matthew Provencher for full treatment details. Commonly, an implantable delivery system is composed of tissue engineering scaffold biomaterials, which should have a three-dimensional structure that allows for cell attachment, growth, and proliferation. 1186/s13018-020-01631-8. Critique of Techniques Used in Rotator Cuff Regeneration. Note: Content may be edited for style and length. Haleem, A., Gohal, C., Leroux, T., Henry, P., Alolabi, B., and Khan, M. Primary Arthroscopic Repair of Massive Rotator Cuff Tears Results in Significant Improvements with Low Rate of Re-Tear. Zone 1 (tendon area) mainly consists of collagen I fibers together with a small amount of decorin. As autologous stem cells, USCs exhibit low immunogenicity, which may cause a low rejection response during treatment. Huegel J, Kim DH, Cirone JM, Pardes AM, Morris TR, Nuss CA, et al.
Wang, M., Yang, Y., Yang, D., Luo, F., Liang, W., Guo, S., et al. These synthetic polymers can be electrospun into nano- and microfibrous scaffolds, which mimic aligned collagen fibers in tendon tissue and promote tenogenic differentiation (Vuornos et al., 2016; Laranjeira et al., 2017; Calejo et al., 2019; El Khatib et al., 2020). Additionally, injection of ADSCs into the musculotendinous junction area of the subscapularis can improve muscle function by electromyographic evaluation and decrease fatty infiltration of the muscle, and it tends to enhance the load-to-failure in chronic rotator cuff tears (Oh et al., 2014). Dr. Provencher often begins osteoarthritis treatment with non-surgical measures such as rest, modified activities, medications, cortisone injections and physical therapy. Several studies have demonstrated the promising results of engineered EVs in tendon repair and regeneration. Multipotential Differentiation of Human Urine-Derived Stem Cells: Potential for Therapeutic Applications in Urology. Moreover, CS is a natural polymer and a major ECM component that has the ability to reduce inflammation by diminishing NF-κB activation and nuclear translocation (Vallières and Du Souich, 2010). Mater 16 (6), 664–670. It is estimated that the prevalence of shoulder problems in primary care is 2.
Preclinical Cell and Gene Therapy. Intraoperative and In Vitro Classification of Subacromial Bursal Tissue. Gulotta LV, Kovacevic D, Ehteshami JR, Dagher E, Packer JD, Rodeo SA. Decellularized matrices have been explored for their regenerative effects on tendon repair; however, tissue resources should be considered. Therefore, UCB-MSCs can be prepared early before treatment, and the function of stem cells is not affected by the age of patients or disease.
MSCs are thought to mediate therapeutic functions in a paracrine manner in addition to their multipotent differentiation capacity and direct intercellular interactions. Islam A, Bohl MS, Tsai AG, Younesi M, Gillespie R, Akkus O. Biomechanical evaluation of a novel suturing scheme for grafting load-bearing collagen scaffolds for rotator cuff repair. Carr AJ, Murphy R, Dakin SG, Rombach I, Wheway K, Watkins B, et al. The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest. Vesicles 9 (1), 1735249. The stem cell procedure is quick, easy, and has no recovery down time! The Effectiveness of the Pilates Method: Reducing the Degree of Non-Structural Scoliosis, and Improving Flexibility and Pain in Female College Students. Additionally, gene-modified stem cells can inhibit inflammation during the healing process. The healing process involves both intrinsic and extrinsic healing processes (Longo et al., 2011).
Both aggrecan and mineral components are present in the extracellular matrix composition. "Clinical studies demonstrate that PRP injections are more effective than steroid injections in the treatment of tennis elbow and can guide practitioners to recommend more effective treatment options for patients with this condition. Comparison of Molecular Profiles of Human Mesenchymal Stem Cells Derived from Bone Marrow, Umbilical Cord Blood, Placenta and Adipose Tissue. 2011a) showed that BMSCs transfected to overexpress Scx promoted the formation of fibrocartilage at the tendon insertion and improved biomechanical strength at 4 weeks for rats who underwent unilateral detachment and repair of the supraspinatus tendon. In our review, natural polymers are most widely used in stem cell therapies for rotator cuff injuries (Gulotta et al., 2010; Gulotta et al., 2011a; Degen et al., 2016; Liu et al., 2019). Early tendon remodeling plays a vital role in tendon regeneration. Collectively, these nano-sized particles with a lipid bilayer, naturally released by cells, are called extracellular vesicles (EVs) (Théry et al., 2018). Medical screening, review of relevant imaging, and physical examination are key to deciding the best treatment approach to address your pain and joint disease or injury. Kim YS, Sung CH, Chung SH, Kwak SJ, Koh YG. The Risk of Achilles Tendon Rupture in the Patients with Achilles Tendinopathy: Healthcare Database Analysis in the United States. A clinical and magnetic resonance imaging study. The untreated BMSCs increased the early formation of fibrocartilage and collagen orientation as well as biomechanical strength at 2 weeks.
"Orthopedic surgeons must be well informed when discussing biologic agents with patients, " added Dr. "It is paramount that orthopedic surgeons provide leadership in this area and work toward developing practice guidelines and policies for the use of biologic agents. Hegedus, E. J., Cook, C., Brennan, M., Wyland, D., Garrison, J. C., and Driesner, D. Vascularity and Tendon Pathology in the Rotator Cuff: A Review of Literature and Implications for Rehabilitation and Surgery. These muscles play a critical role in both movement and dynamic stabilization during the locomotion of the shoulder joint (Lin et al., 2018). The scar tissue lacks the gradient of mineral distribution, and the diameter of collagen III fibers is smaller than that of collagen I fibers (Hexter et al., 2017). Studies that adopted a human model reported a significant improvement in scores (Table 2) such as the VAS, Constant-Murley score, UCLA, and shoulder external rotation [6, 7, 13, 22].
It was found that the prevalence of sonographic full-thickness rotator cuff tears was 10. Calejo, I., Costa-Almeida, R., Reis, R. L., and Gomes, M. E. (2019). Española Cirugía Ortopédica Traumatol. Owing to the tear of enthesis (Zones 3 and 4) in rotator cuff injuries, it was meaningful to transfer osteogenic and chondrogenic genes to enhance tendon–bone healing.
