Chondrocytes are the exclusive cells residing in cartilage and maintain the functionality of cartilage tissue. Series of biocomponents such as different growth factors, cytokines, and transcriptional factors regulate the mesenchymal stem cells (MSCs) differentiation to chondrocytes. The number of chondrocytes and dedifferentiation are the key limitations in subsequent clinical application of the chondrocytes. Different culture methods are being developed to overcome such issues. Using tissue engineering and cell based approaches, chondrocytes offer prominent therapeutic option specifically in orthopedics for cartilage repair and to treat ailments such as tracheal defects, facial reconstruction, and urinary incontinence. Matrix-assisted autologous chondrocyte transplantation/implantation is an improved version of traditional autologous chondrocyte transplantation (ACT) method. An increasing number of studies show the clinical significance of this technique for the chondral lesions treatment.

Module 2 : Anatomy – the Skeleton
Module 2 : Anatomy – The Skeleton In this module you will learn: The functions of the skeletal system The types of bones in the human body The effects of exercise on your bones What happens to the bones as we get older When studying to become a fitness instructor or personal trainer, you will learn all about the anatomy of the human body. Studying the skeleton is one of the foundations of your trade, you will need to know how the body is structured, the names of each bone, types of bones, importance of bone and joint health, detail of the spine and different terms of movement. Without stating the obvious, each of your clients has their own skeleton and you must be fully aware of how this works. This is for many reasons; you are a teacher and must be fully aware of how to prevent injuries, avoid unnecessary stress on the bones and, if qualified, help the client prevent or heal bone and joint related conditions or medical problems. 2.1 Understanding the Skeletal System The skeleton is comprised of 206 different bones that provide 5 main functions: Support mechanism for muscle and tissue Protection for organs Movement with bones, muscles, and joints Storing minerals and blood cells Growth Skeletal System 2.2 Bones are Formed by Ossification Some bones (such as the flat bones of your skull) in the body are formed in a similar stage to connective tissue. The process is known as direct or intramembranous ossification. Other bones are made up of cartilaginous matter, this is developed from future bone in the embryo which then dissolves and is replaced with other bone cells.

Studies on Brain and Spinal Cord Tumors
Studies on Brain and Spinal Cord Tumors Chapter 1 Osteochondroma of the Spine Iraj Lotfinia Professor of Neurosurgery, Tabriz Universsity of medical science, Tabriz, Iran. Fax: 00984113340830; Email: [email protected] Abstract Osteochondroma (OC) is the most common benign tumor of the bones, and it remains the most common precursor for secondary chondrosarcoma, which often occurs in the long bones’ metaphyseal areas. Rarely, it is also found in the spine. This tumor comprises a cartilage capped bone projection and is observed in both solitary and multiple forms. In many cases, the lesion can be definitively diagnosed according to radiological characteristics, but the rarity of these lesions in the spine, gradual onset of symptoms, and the frequent lack of observation of lesions in plain radiography may delay the diagnosis or cause misdiagnosis. These lesions are be- nign and do not risk the patient’s life; however, they rarely may be found to be a malignant degeneration that transformed into chondrosarcoma. When the lesion has led to clinical symptoms or has faced the patient with cosmetic challenges, or when definitive diagnosis is unknown, treatment is required. The primary treatment is the surgical removal of the lesion. Timely diagnosis and complete resection of the le- sion using surgery lead to complete recovery and prevent recurrence. 1. Introduction According to the World Health Organization’s (WHO’s) definition in 2002, osteocar- tilaginous exostosis are benign bone neoplasms covered by a cartilaginous cap created at the outer surface of the bone by endochondral ossification [1]. Osteochondroma (OC) is the most common benign primary tumor of the bone.

Human infrapatellar fat pad-sourced mesenchymal stem cells (IFP-MSC) are an arthroscopically accessible source of mesenchymal stem cells (MSC) for the repair of articular cartilage defects. Human IFP-MSC exists physiologically under a low oxygen tension (i.e., 1–5%) Edited by: microenvironment.

Bone Cartilage Dense Fibrous CT (Tendons & Nonelastic Ligaments) Dense Elastic CT (Elastic Ligaments)
Chapter 6 Content Review Questions 1-8 1. The skeletal system consists of what connective tissues? Bone Cartilage Dense fibrous CT (tendons & nonelastic ligaments) Dense elastic CT (elastic ligaments) List the functions of these tissues. Bone: supports the body, protects internal organs, provides levers on which muscles act, store minerals, and produce blood cells. Cartilage provides a model for bone formation and growth, provides a smooth cushion between adjacent bones, and provides firm, flexible support. Tendons attach muscles to bones and ligaments attach bone to bone. 2. Name the major types of fibers and molecules found in the extracellular matrix of the skeletal system. Collagen Proteoglycans Hydroxyapatite Water Minerals How do they contribute to the functions of tendons, ligaments, cartilage and bones? The collagen fibers of tendons and ligaments make these structures very tough, like ropes or cables. Collagen makes cartilage tough, whereas the water-filled proteoglycans make it smooth and resistant. As a result, cartilage is relatively rigid, but springs back to its original shape if it is bent or slightly compressed, and it is an excellent shock absorber. The extracellular matrix of bone contains collagen and minerals, including calcium and phosphate. Collagen is a tough, ropelike protein, which lends flexible strength to the bone. The mineral component gives the bone compression (weight-bearing) strength. Most of the mineral in the bone is in the form of hydroxyapatite. 3. Define the terms diaphysis, epiphysis, epiphyseal plate, medullary cavity, articular cartilage, periosteum, and endosteum. Diaphysis – the central shaft of a long bone. Epiphysis – the ends of a long bone. Epiphyseal plate – the site of growth in bone length, found between each epiphysis and diaphysis of a long bone and composed of cartilage.

The Histology of Epiphyseal Union in Mammals
J. Anat. (1975), 120, 1, pp. 1-25 With 49 figures Printed in Great Britain The histology of epiphyseal union in mammals R. WHEELER HAINES* Visiting Professor, Department of Anatomy, Royal Free Hospital School of Medicine, London (Accepted 11 November 1974) INTRODUCTION Epiphyseal union may be defined as beginning with the completion of the first mineralized bridge between epiphyseal and diaphyseal bone and ending with the complete disappearance of the cartilaginous epiphyseal plate and its replacement by bone and marrow. The phases have been described by Sidhom & Derry (1931) and many others from radiographs, but histological material showing union in progress is rare, probably because of the rapidity with which union, once begun, comes to completion (Stephenson, 1924; Dawson, 1929). Dawson (1925, 1929) described the histology of 'lapsed union' in rats, where the larger epiphyses at the 'growing ends' of the long bones remain un-united through- out life. He and Becks et al. (1948) also discussed the early and complete type of union found at the distal end of the humerus in the rat. Here a single narrow per- foration pierced the cartilaginous plate near the olecranon fossa and later spread to destroy the whole plate. Lassila (1928) described a different type of union in the metatarsus of the calf, with multiple perforations of the plate. Apart from a few notes on human material (Haines & Mohiuddin, 1960, 1968), nothing else seems to have been published on the histology of union in mammals. In this paper more abundant material from dog and man is presented and will serve as a basis for discussion of the main features of the different types of union.
