Article Abstract

Tendons and ligaments are essential connective tissues that connect the muscle and bone. Their recovery from injuries is known to be poor, highlighting the crucial need for an effective therapy. A few reports have described the development of artificial ligaments with sufficient strength from human cells. In this study, we successfully generated a tendon-like tissue (bio-tendon) using human induced pluripotent stem cells (iPSCs). We first differentiated human iPSCs into mesenchymal stem cells (iPSC-MSCs) and transfected them with Mohawk (Mkx) to obtain Mkx-iPSC-MSCs, which were applied to a newly designed chamber with a mechanical stretch incubation system. The embedded Mkx-iPSC-MSCs created bio-tendons and exhibited an aligned extracellular matrix structure. Transplantation of the bio-tendons into a mouse Achilles tendon rupture model showed host-derived cell infiltration with improved histological score and biomechanical properties. Taken together, the bio-tendon generated in this study has potential clinical applications for tendon/ligament-related injuries and diseases.

Objective: The myodural bridge complex (MDBC) is a tendon-like structure highly conserved during vertebrate evolution, suggesting it plays an important physiological role. Substantial evidence indicates that the MDBC may contribute to cerebrospinal fluid (CSF) circulation by generating mechanical force. Studying its developmental process may offer new insights into CSF dynamics and lead to improved strategies for diagnosing and treating neurodegenerative diseases.

The development of a functional musculoskeletal system requires the combination of contractile muscle and extracellular matrix (ECM)-rich tendons that transmit muscle-generated force to bone. Despite the different embryologic origins, muscle and tendon integrate at the myotendinous junction (MTJ) to connect across this interface. While the cell-cell signaling factors have received considerable attention, how the ECM links these tissues remains unclear.

Tendon injuries rank among the most common musculoskeletal disorders, with their incidence rising steadily due to increased sports participation and an aging population. Current surgical treatments often fall short of clinical expectations due to poor biocompatibility, suboptimal mechanical properties, and frequent post-surgical fibrosis. Tissue engineering, however, offers promising alternatives by using biocompatible scaffolds that mimic the native tendon structure.

Tendon regeneration has been one of the most challenging issues in orthopedics. Despite various surgical techniques and rehabilitation methods, tendon tears or ruptures cannot wholly regenerate and gain the load-bearing capacity the tendon tissue had before the injury. The enhancement of tendon regeneration mostly requires grafting or an artificial tendon-like tissue to replace the damaged tendon.

Active synthesis of type I collagen homotrimer in Dupuytren's fibrosis is unaffected by anti-TNF-α treatment.

Dupuytren's disease is a common fibroproliferative disease of the palmar fascia of the hand, with advanced cases treated surgically. Anti-TNF injection has undergone phase 2 trials and may be effective in slowing early-stage disease progression. Here we sought to determine how new synthesis of type I collagen in Dupuytren's differs from normal palmar fascia samples and to analyze the role of TNF in aberrant collagen synthesis.
