Connectomics of the Lacuno-Canalicular Network in Bone
The Small World of Osteocytes: Connectomics of the Lacuno-Canalicular Network in Bone Philip Kollmannsberger1,2,*, Michael Kerschnitzki1,3, Felix Repp1, Wolfgang Wagermaier1, Richard Weinkamer1, Peter Fratzl1 1Max Planck Institute of Colloids and Interfaces, Department of Biomaterials, Potsdam, Germany 2ETH Zurich, Laboratory of Applied Mechanobiology, Department of Health Sciences and Technology, Zurich, Switzerland 3Weizmann Institute of Science, Dept. of Structural Biology, Rehovot, Israel * current address: Center for Computational and Theoretical Biology, University of Würzburg, Würzburg, Germany Abstract Osteocytes and their cell processes reside in a large, interconnected network of voids pervading the mineralized bone matrix of most vertebrates. This osteocyte lacuno-canalicular network (OLCN) is believed to play important roles in mechanosensing, mineral homeostasis, and for the mechanical properties of bone. While the extracellular matrix structure of bone is extensively studied on ultrastructural and macroscopic scales, there is a lack of quantitative knowledge on how the cellular network is organized. Using a recently introduced imaging and quantification approach, we analyze the OLCN in different bone types from mouse and sheep that exhibit different degrees of structural organization not only of the cell network but also of the fibrous matrix deposited by the cells. We define a number of robust, quantitative measures that are derived from the theory of complex networks. These measures enable us to gain insights into how efficient the network is organized with regard to intercellular transport and communication. Our analysis shows that the cell network in regularly organized, slow-growing bone tissue from sheep is less connected, but more efficiently organized compared to irregular and fast-growing bone tissue from mice. -

FROST, M.D. INTRODUCTION Thc osteocyte differs trom the rest of thc somatic cells in that it resides in a lacuna with walls made of bone. With the exception of halo volume peculiarities," the bone enveloping an osteocyte is impervious to organic and inorganic ions and molecules. If no special provision for diffusion of nutrients existed, osteocytes would promptly dic.^ A diffusion pathway is provided thc osteocytes in thc system of canaliculae which -onnect osteocyte lacunae to vascular channels. This is the pathway through which he average osteocyte obtains anabolic substances and excretes catabolic substances. \ u. Jt ( Figure 1 "•oo X.

Skeletal System
Skeletal System Overview • The skeletal system composed of bones, cartilages, joints, and ligaments, accounts for about 20% of the body mass (i.e., about 30 pounds in a 160-pound person). o Bones make up most of the skeleton o Cartilages occur only in isolated areas, such as the nose, parts of ribs, and the joints o Ligaments connect bones and reinforce joints, allowing required movements while restricting motions in other directions. o Joints are the junctions between bones which provide for the mobility of the skeleton Skeletal Cartilages • Human skeleton initially made up of cartilages and fibrous membranes; most are soon replaced with bone • In adults, the few areas where cartilage remains are mainly where flexible skeletal tissue is needed. • Cartilage tissue consists mainly of water—approximately 80%; high water content allows cartilage to be resilient (i.e., spring back to its original shape after being compressed). • Cartilage contains no nerves or blood vessels. • Perichondrium (“around the cartilage”) is dense irregular connective tissue; surrounds the cartilage and acts like a girdle to resist outward expansion when cartilage is compressed. o Perichondrium contains the blood vessels from which nutrients diffuse through the matrix to reach the cartilage cells. This mode of nutrient delivery limits cartilage thickness. • Three types of Cartilage Tissue in body o All three have cells called chondrocytes encased in small cavities (called lacunae) within an extracellular matrix containing a jellylike ground substance and fibers. o Skeletal cartilages contain representatives from all three types. Hyaline cartilages • Looks like frosted glass • Most abundant skeletal cartilages • Their chondrocytes appear spherical • Only fiber type in their matrix is fine collagen (undetectable microscopically) • Skeletal hyaline cartilages include: o Articular Cartilages —cover ends of most bones at movable joints o Costal cartilages —connect ribs to sternum o Respiratory cartilages —form skeleton of the larynx (voicebox) and reinforce other respiratory passages. -
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. -

Cartilage Development and Maturation In Vitro and In Vivo Johnathan Ng Submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy in the Graduate School of Arts and Sciences Columbia University 2017 © 2017 Johnathan Ng All rights reserved Abstract Cartilage Development and Maturation In Vitro and In Vivo Johnathan Ng The articular cartilage has a limited capacity to regenerate. Cartilage lesions often result in degeneration, leading to osteoarthritis. Current treatments are mostly palliative and reparative, and fail to restore cartilage function in the long term due to the replacement of hyaline cartilage with fibrocartilage. Although a stem-cell based approach towards regenerating the articular cartilage is attractive, cartilage generated from human mesenchymal stem cells (hMSCs) often lack the function, organization and stability of the native cartilage. Thus, there is a need to develop effective methods to engineer physiologic cartilage tissues from hMSCs in vitro and assess their outcomes in vivo. This dissertation focused on three coordinated aims: establish a simple in vivo model for studying the maturation of osteochondral tissues by showing that subcutaneous implantation in a mouse recapitulates native endochondral ossification (Aim 1), (ii) develop a robust method for engineering physiologic cartilage discs from self-assembling hMSCs (Aim 2), and (iii) improve the organization and stability of cartilage discs by implementing spatiotemporal control during induction in vitro (Aim 3). First, the usefulness of subcutaneous implantation in mice for studying the development and maintenance of osteochondral tissues in vivo was determined. By studying juvenile bovine osteochondral tissues, similarities in the profiles of endochondral ossification between the native and ectopic processes were observed. -

Variations in the Quantity of Uncalcified Fibrocartilage at the Insertions of the Extrinsic Calf Muscles in the Foot
J. Anat. (1995) 186, pp. 417-421, with 4 figures Printed in Great Britain 417 Short Report Variations in the quantity of uncalcified fibrocartilage at the insertions of the extrinsic calf muscles in the foot P. FROWEN AND M. BENJAMIN School of Molecular and Medical Biosciences (Anatomy Unit), University of Wales College of Cardiff, UK (Accepted 13 October 1994) ABSTRACT It has been suggested that fibrocartilage at entheses (tendon-bone junctions) prevents collagen fibres bending at the hard tissue interface. We have investigated this function by exploring the relationship between the presence or amount of fibrocartilage at the attachments of the major extrinsic muscles in the foot, and the extent to which these tendons bend near their entheses during movement. The tendons were taken from each of 5 formalin-fixed dissecting room cadavers and prepared for routine histology, and sections were collected systematically throughout the blocks. Tendons that attached to the tarsus and metatarsus had fibrocartilaginous entheses, but those attached to the phalanges had fibrous entheses. In all tarsal and metatarsal tendons, the fibrocartilage was significantly thicker (P < 0.05) in the deepest part of the enthesis. Here the greatest amount of fibrocartilage was in the Achilles tendon (mean thickness + S.E.M.: 1560 + 161 gim). There were moderate amounts at the medial cuneiform attachment of tibialis anterior (533 + 82 gm), peroneus brevis (472 + 64 gm) and tibialis posterior (454 +26 gm), small quantities at the first metatarsal attachment of tibialis anterior (104+ 14 gm) and peroneus longus (21 + 8 pm), but only traces at the attachments of the flexor and extensor tendons of the phalanges. -

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.
