The Open Rehabilitation Journal Open Access Ligament. The attachment of dissimilar materials is a major engineering challenge, yet this challenge is seemingly overcome in biology. This study aimed to determine how the transcription factor Scleraxis (Scx) influences the development and maturation of the tendon-to-bone attachment (enthesis)., Tendons, such as the flexor digitorum profundus tendons of the hand and the Achilles tendon of the foot, and ligaments, such as the collateral and cruciate ligaments of the knee, are frequently injured..

The cell biology of suturing tendons Sarah Al Youha. Abstract In this chapter, biomechanical methods used to analyze healing and repair of ligaments and tendons are initially described such that the tensile properties of these soft tissues as well as their contribution to joint motion can be determined., To date, most developmental studies of tendon formation have concentrated on the limb tendons, and in particular, on the morphogenesis of the distal autopod tendons (Benjamin and Ralphs, 2000). The patterning of specific distal tendons is preceded by an extracellular matrix (ECM) scaffold that is present in the hand plate from stage 27 onwards ( Hurle et al., 1989 )..

Furthermore, transplantation of the genetical transduced stem cells by “Scleraxis,” which is a transcription factor involving tendon development, have been used for effective tendon regeneration (Gulotta and Rodeo, 2011).

The scaffold could be designed to encourage not only cell migration and proliferation, but also to encourage vascular and nerve ingrowth, as well as collagen and protein production. The development of this new method has involved the systematic investigation of several questions related to the biology of the Tendon Regeneration: Understanding Tissue Physiology and Development to Engineer Functional Substitutes is the first book to highlight the multi-disciplinary nature of this specialized field and the importance of collaboration between medical and engineering laboratories in the development of tissue-oriented products for tissue engineering and regenerative medicine (TERM) strategies.

Molecular Regulation of Tendon Cell Fate During Development Alice H. Huang,1 Helen H. Lu,2 Ronen Schweitzer3 1Department of Orthopaedics, Icahn School of Medicine at Mount Sinai, New York, NY, 2Department of Biomedical Engineering, Columbia As noted in the previous chapter and as reviewed extensively elsewhere (Frank 1985, 1988; Akeson 1984), both tendons and ligaments are highly complex structures with a number of unique functional characteristics. While similar in many ways, tendons and ligaments have some important differences in

Furthermore, transplantation of the genetical transduced stem cells by “Scleraxis,” which is a transcription factor involving tendon development, have been used for effective tendon regeneration (Gulotta and Rodeo, 2011). Tendons are bands of connective tissues that are particularly rich in collagens. The most abundant tendon component is type I collagen, which constitutes about 70–80 % of the dry tendon mass and about 95 % of the total collagen in tendons [1, 2, 3].

Her laboratory uses zebrafish genetics and stem cells to understand how tendons and ligaments form, organize, and regenerate with the ultimate goal of applying this knowledge towards the development of improved therapies for tendon and ligament injuries.

Tendon disorders are a major problem in sports and occupational medicine. Tendons have the highest tensile strength of all connective tissue because of a high proportion of collagen in the fibres and their closely packed parallel arrangement in the direction of force. The individual collagen fibrils ruptured ligament to facilitate ingrowth of cells into the gap between the remnants. The scaffold could be designed to encourage not only cell migration and proliferation, but also to encourage vascular and nerve ingrowth, as well as collagen and protein production.

The purpose of this study is to determine whether FT-SHG imaging can be used as a We demonstrated a series of detrimental effects of AAS and aging on functional and biomechanical parameters, including the volume density of blood vessel cells, adipose tissue cells, tendon calcification, collagen content, the regulation of the major proteins related to the metabolic/development processes of tendons, and ECM remodeling. Conversely, RT seems to mitigate age-related tendon

Material Properties: Characteristics . tendons contain more collagen and are less viscoelastic than ligaments; viscoelastic behavior with nonlinear elasticity These processes cause alterations in the biology and biomechanics of the injured ligament, leading to inadequate healing and tissue formation that is inferior to the tissue it has replaced. The incomplete healing and lower integrity of the new ligament tissue results in ligament laxity, predisposing the joint to further injury. This cycle of ligament injury and subsequent laxity causes joint

The Biology of Tendons and Ligaments 45 Figure 4A: Transmission E.M. photograph of ruthenium red stained MCL cross section showing apparent connections of cell processes (magnification X 16,000)., The poor and slow healing capacity of tendons requires novel strategies to speed up the tendon repair process. Hence, new and promising developments in tendon tissue engineering have become increasingly relevant. Previously, we have established a tendon progenitor cell line via ectopic expression of the tendon-related basic helix-loop-helix.

The development of zebrafish tendon and ligament. In the head (a) and limbs (b), tendons initiate their development independently of muscle, but further tendon development requires the presence of muscle. In contrast, the initiation of axial tendon development requires the presence of muscle (c). Although developmental processes of tendon and ligament tissues and the phenotypes of mice with genetic deletion of the key transcription factors are different (see the sections Biology of Mature Tendon and Ligament Tissues and Cells, and Developmental Biology of Tendon and Ligament Tissues and Cells), the basic structures of these tissues and the gene expression profiles of their major cell.

Indeed, Scx is expressed in tendon and ligament cells from embryonic to adult stages, and in all anatomical locations where tendons and ligaments arise (Brent et al., 2003; Schweitzer et al., 2001). However, relative to the other musculoskeletal tissues, tendons and ligaments have received less attention, and many questions remain as to the molecular mechanisms underlying their development. Tendon Regeneration: Understanding Tissue Physiology and Development to Engineer Functional Substitutes is the first book to highlight the multi-disciplinary nature of this specialized field and the importance of collaboration between medical and engineering laboratories in the development of tissue-oriented products for tissue engineering and regenerative medicine (TERM) strategies.

Embryology is central to evolutionary developmental biology, which studies the genetic control of the development process (e.g. morphogens), its link to cell signaling, its roles in certain diseases and mutations, and its links to stem cell research. The tendon progenitors are induced at the sclerotome's edge, at the expense of skeletogenic Pax1 positive cells and in response to FGF signaling in the adjacent myotome. The tendon primordia thus form in a location abutting the two tissues that the mature tendons must ultimately connect. Tendon progenitor formation may reveal a general mechanism for the specification of other somitic

106) Tendons are composed of dense regular connective tissue, which consists of densely packed, parallel connective tissue fibers. This type of tissue has relatively few cells and vascular supply is poor; consequently, repair is slow.
