Differences in the biological properties of mesenchymal stromal cells from traumatic temporomandibular joint fibrous and bony ankylosis: a comparative study [PDF]

open access: yesAnimal Cells and Systems, 2021
The aim of this study was to compare the functional characteristics of mesenchymal stromal cells (MSCs) from a sheep model of traumatic temporomandibular joint (TMJ) fibrous and bony ankylosis.

Human Mesenchymal Stromal Cell Sheet Enhances Allograft Repair in a Mouse Model [PDF]

open access: yesScientific Reports, 2017
To determine whether cell sheets generated with long-term passaged (P10) aging human mesenchymal stromal cells (MSCs) could be used for bone tissue regeneration as tissue engineered periosteum in a femoral allograft mouse model similar to fresh passaged (

Fully automated segmentation of callus by micro-CT compared to biomechanics [PDF]

open access: yesJournal of Orthopaedic Surgery and Research, 2017
Background A high percentage of closed femur fractures have slight comminution. Using micro-CT (μCT), multiple fragment segmentation is much more difficult than segmentation of unfractured or osteotomied bone.

Utility of ultrasound imaging in monitoring fracture healing in rat femur: Comparison with other imaging modalities [PDF]

open access: yesBone Reports
Objective: Fractures are common injuries and various imaging modalities are employed to diagnose and monitor bone union. However, the follow-up of fracture healing using ultrasound imaging (US) remains a topic of debate.

Increased Osteoblast GαS Promotes Ossification by Suppressing Cartilage and Enhancing Callus Mineralization During Fracture Repair in Mice [PDF]

open access: yesJBMR Plus, 2023
GαS, the stimulatory G protein α‐subunit that raises intracellular cAMP levels by activating adenylyl cyclase, plays a vital role in bone development, maintenance, and remodeling. Previously, using transgenic mice overexpressing GαS in osteoblasts (GS‐Tg)

High dose teriparatide (rPTH1-34) therapy increases callus volume and enhances radiographic healing at 8-weeks in a massive canine femoral allograft model. [PDF]

open access: yesPLoS ONE, 2017
Small animal studies have demonstrated significant high-dose recombinant parathyroid hormone1-34 (rPTH1-34) effects on intercalary allograft healing. Towards a human adjuvant therapy to decrease non-unions, we evaluated rPTH1-34 safety and efficacy in a ...

Association of bone fracture type and degree of callus formation with leptin concentration in children with long bone fractures [PDF]

open access: yesVojnosanitetski Pregled, 2021
Background/Aim. Recent studies indicate that adipokines have an important role in bone physiology and pathology. Recent data indicate that adipokine leptin functions as a regulator of bone growth at multiple levels, systemically and locally.

Exogenous PTH 1-34 Attenuates Impaired Fracture Healing in Endogenous PTH Deficiency Mice via Activating Indian Hedgehog Signaling Pathway and Accelerating Endochondral Ossification

open access: yesFrontiers in Cell and Developmental Biology, 2022
Fracture healing is a complicated, long-term, and multistage repair process. Intermittent administration of parathyroid hormone (PTH) has been proven effective on intramembranous and endochondral bone formation during the fracture healing process ...

The role of hypertrophic chondrocytes in fracture healing

open access: yes生物医学转化, 2023
Fracture healing is a multifactorial process. Most fractures are healed by the process of endochondral ossification, involving the formation of a cartilaginous soft callus and the process of cartilage-tobone transition.
