  • Mesenchymal Stem Cells in Combination with Hyaluronic Acid
    www.nature.com/scientificreports OPEN Mesenchymal Stem Cells in Combination with Hyaluronic Acid for Articular Cartilage Defects Received: 1 August 2017 Lang Li1, Xin Duan1, Zhaoxin Fan2, Long Chen1,3, Fei Xing1, Zhao Xu4, Qiang Chen2,5 & Accepted: 19 April 2018 Zhou Xiang1 Published: xx xx xxxx Mesenchymal stem cells (MSCs) and hyaluronic acid (HA) have been found in previous studies to have great potential for medical use. This study aimed to investigate the therapeutic efects of bone marrow mesenchymal stem cells (BMSCs) combined with HA on articular cartilage repair in canines. Twenty-four healthy canines (48 knee-joints), male or female with weight ranging from 5 to 6 kg, were operated on to induce cartilage defect model and divided into 3 groups randomly which received diferent treatments: BMSCs plus HA (BMSCs-HA), HA alone, and saline. Twenty-eight weeks after treatment, all canines were sacrifced and analyzed by gross appearance, magnetic resonance imaging (MRI), hematoxylin-eosin (HE) staining, Masson staining, toluidine blue staining, type II collagen immunohistochemistry, gross grading scale and histological scores. MSCs plus HA regenerated more cartilage-like tissue than did HA alone or saline. According to the macroscopic evaluation and histological assessment score, treatment with MSCs plus HA also lead to signifcant improvement in cartilage defects compared to those in the other 2 treatment groups (P < 0.05). These fndings suggested that allogeneic BMSCs plus HA rather than HA alone was efective in promoting the formation of cartilage-like tissue for repairing cartilage defect in canines. Articular cartilage is composed of chondrocyte and extracellular matrix and has an important role in joint move- ment including lubrication, shock absorption and conduction.

  • Autologous Matrix-Induced Chondrogenesis and Generational Development of Autologous Chondrocyte Implantation
    Autologous Matrix-Induced Chondrogenesis and Generational Development of Autologous Chondrocyte Implantation Hajo Thermann, MD, PhD,* Christoph Becher, MD,† Francesca Vannini, MD, PhD,‡ and Sandro Giannini, MD‡ The treatment of osteochondral defects of the talus is still controversial. Matrix-guided treatment options for covering of the defect with a scaffold have gained increasing popularity. Cellular-based autologous chondrocyte implantation (ACI) has undergone a generational development overcoming the surgical drawbacks related to the use of the periosteal flap over time. As ACI is associated with high costs and limited in availability, autologous matrix-induced chondrogenesis, a single-step procedure combining microfracturing of the subchondral bone to release bone marrow mesenchymal stem cells in combination with the coverage of an acellular matrix, has gained increasing popularity. The purposes of this report are to present the arthroscopic approach of the matrix-guided autologous matrix-induced chondrogenesis technique and generational development of ACI in the treatment of chondral and osteochon- dral defects of the talus.

Methods: A total of 30 patients who underwent MF and 20 who received DeNovo NT for JACI-BMAC treatment between 2006 and 2014 were included. Additionally, 17 MF patients received supplemental BMAC treatment. Retrospective chart review was performed and functional outcomes were assessed pre- and postoperatively using the Foot and Ankle Outcome Score and Visual Analog pain scale. Postoperative magnetic resonance images were reviewed and evaluated using a modified Magnetic Resonance Observation of Cartilage Tissue (MOCART) score. Average follow-up for functional outcomes was 30.9 months (range, 12-79 months). Radiographically, average follow-up was 28.1 months (range, 12-97 months). Results: Both the MF and JACI-BMAC showed significant pre- to postoperative improvements in all Foot and Ankle Outcome Score subscales.

  • Synthetic Cartilage Implants for Joint Pain
    Corporate Medical Policy Synthetic Cartilage Implants for Joint Pain File Name: synthetic_cartilage_implants_for_joint_pain Origination: 1/2018 Last CAP Review: 2/2021 Next CAP Review: 2/2022 Last Review: 2/2021 Description of Procedure or Service ARTICULAR CARTILAGE DAMAGE Articular cartilage damage may present as focal lesions or as more diffuse osteoarthritis (OA). Cartilage is a biological hydrogel that is comprised mostly of water with collagen and glycosaminoglycans and does not typically heal on its own. OA or focal articular cartilage lesions can be associated with substantial pain, loss of function, and disability. OA is most frequently observed in the knees, hips, interphalangeal joints, first carpometacarpal joints, first metatarsophalangeal (MTP) joint, and apophyseal (facet) joints of the lower cervical and lower lumbar spine. OA less commonly affects the elbow, wrist, shoulder, and ankle. Knee OA is the most common cause of lower-limb disability in adults over age 50. OA of the MTP joint with loss of motion (hallux rigidus) can also be severely disabling due to pain in the “toe-off” position of gait. An epidemiologic study found that OA of the first MTP joint may be present in as many as 1 in 40 people over the age of 50. Treatment Treatment may include débridement, abrasion techniques, osteochondral autografting, and autologous chondrocyte implantation. Débridement involves the removal of the synovial membrane, osteophytes, loose articular debris, and diseased cartilage and is capable of producing symptomatic relief. Subchondral abrasion techniques attempt to restore the articular surface by inducing the growth of fibrocartilage into the chondral defect. Diffuse OA of the knee, hip, shoulder, or ankle may be treated with joint replacement.

  • 16 Cartilage
    Cartilage Cartilage serves as a rigid yet lightweight and flexible supporting tissue. It forms the framework for the respiratory passages to prevent their collapse, provides smooth "bearings" at joints, and forms a cushion between the vertebrae, acting as a shock absorber for the spine. Cartilage is important in determining the size and shape of bones and provides the growing areas in many bones. Its capacity for rapid growth while maintaining stiffness makes cartilage suitable for the embryonic skeleton. About 75% of the water in cartilage is bound to proteoglycans, and these compounds are important in the transport of fluids, electrolytes, and nutrients throughout the cartilage matrix. Although adapted to provide support, cartilage contains only the usual elements of connective tissue cells, fibers, and ground substance. It is the ground substance that gives cartilage its firm consistency and ability to withstand compression and shearing forces. Collagen and elastic fibers embedded in the ground substance impart tensile strength and elasticity. Together, the fibers and ground substance form the matrix of cartilage. Cartilage differs from other connective tissues in that it lacks nerves, blood and lymphatic vessels and is nourished entirely by diffusion of materials from blood vessels in adjacent tissues. Although relatively rigid, the cartilage matrix has high water content and is freely permeable, even to fairly large particles. Classification of cartilage into hyaline, elastic, and fibrous types is based on differences in the abundance and type of fibers in the matrix. Hyaline Cartilage Hyaline cartilage is the most common type of cartilage and forms the costal cartilages, articular cartilages of joints, and cartilages of the nose, larynx, trachea, and bronchi.

  • Musculo-Skeletal System
    Musculo-Skeletal System (Trunk, Limbs, and Head) somite: ectoderm dermatome General Statements: myotome Bilaterally, paraxial mesoderm become sclerotome neural crest somites and somitomeres. (Somitomeres develop ros- intermediate tral to the notochord in the head. They are like somites, but mesoderm neural tube smaller and less distinctly organized.) The mesoderm somatic mesoderm comprising each somite differentiates into three notochord regions: endoderm aorta — dermatome (lateral) which migrates to form dermis of the skin coelom — sclerotome (medial) forms most of the splanchnic mesoderm axial skeleton (vertebrae, ribs, and base of the skull). Mesoderm Regions — myotome (middle) forms skeletal mus- culature. Individual adult muscles are produced by merger of adjacent myotomes. Note: Nerves make early connections with adjacent myotomes and dermatomes, establishing a segmental innervation pattern. As myotome/dermatome cells migrate to assume adult positions, the segmental nerve supply must follow along to maintain its connection to the innervation target. (Recurrent laryngeal & phrenic nerves travel long distances because their targets migrated far away.) Skin. Consists of dermis and epidermis. Epidermis, including hair follicles & glands, is derived from ectoderm. Neural crest cells migrate into epidermis and become melanocytes. (Other neural crest cells become tactile disc receptors.) Dermis arises from mesoderm (dermatomes of somites). Each dermatome forms a continu- ous area of skin innervated by one spinal nerve. Because adjacent dermatomes overlap, a locus of adult skin is formed by 2 or 3 dermatomes, and innervated by 2 or 3 spinal nerves. Muscle. Muscles develop from mesoderm, except for muscles of the iris which arise from optic cup ectoderm. Cardiac and smooth muscles originate from splanchnic mesoderm.

Under the auspices of the World Association of Veterinary Anatomists (W.A.V.A.), the International Committee on Veterinary Anatomical Nomenclature (I.C.V.A.N.) appointed in Giessen, 1965, a Subcommittee on Histology and Embryology which started a working relation with the Subcommittee on Histology of the former International Anatomical Nomenclature Committee. In Mexico City, 1971, this Subcommittee presented a document entitled Nomina Histologica Veterinaria: A Working Draft as a basis for the continued work of the newly-appointed Subcommittee on Histological Nomenclature. This resulted in the editing of the Nomina Histologica Veterinaria: A Working Draft II (Toulouse, 1974), followed by preparations for publication of a Nomina Histologica Veterinaria.
