Modulation of fracture healing by the transient accumulation of senescent cells

open access: yeseLife, 2021
Senescent cells have detrimental effects across tissues with aging but may have beneficial effects on tissue repair, specifically on skin wound healing. However, the potential role of senescent cells in fracture healing has not been defined.

Exosomes from human umbilical cord mesenchymal stem cells enhance fracture healing through HIF‐1α‐mediated promotion of angiogenesis in a rat model of stabilized fracture

open access: yesCell Proliferation, 2019
Exosomes, as important players in intercellular communication due to their ability to transfer certain molecules to target cells, are believed to take similar effects in promoting bone regeneration with their derived stem cells.

Mesenchymal Stem Cell-Derived Exosomes Promote Fracture Healing in a Mouse Model

open access: yesStem Cells Translational Medicine, 2016
Paracrine signaling by bone‐marrow‐derived mesenchymal stem cells (MSCs) plays a major role in tissue repair. Although the production of regulatory cytokines by MSC transplantation is a critical modulator of tissue regeneration, we focused on exosomes ...

Effectiveness of Teriparatide on Fracture Healing: A Systematic Review and Meta-Analysis.

open access: yesPLoS ONE, 2016
PurposeNowadays, the efficacy of teriparatide in treating osteoporosis was widely accepted, but the discussion about using teriparatide to enhance fracture healing hasn't come to an agreement.

Biomechanical Characteristics of Osteoporotic Fracture Healing in Ovariectomized Rats: A Systematic Review.

open access: yesPLoS ONE, 2016
Biomechanical tests are widely used in animal studies on osteoporotic fracture healing. However, the biomechanical recovery process is still unknown, leading to difficulty in choosing time points for biomechanical tests and in correctly assessing ...

Fracture Healing in the Setting of Endocrine Diseases, Aging, and Cellular Senescence.

open access: yesEndocrine reviews, 2022
Over 2.1 million age-related fractures occur in the United States annually, resulting in an immense socioeconomic burden. Importantly, the age-related deterioration of bone structure is associated with impaired bone healing. Fracture healing is a dynamic

Mechanosensitive Piezo1 is crucial for periosteal stem cell-mediated fracture healing

open access: yesInternational Journal on Biological Sciences, 2022
The biomechanical environment plays a dominant role in fracture healing, and Piezo1 is regarded as a major mechanosensor in bone homeostasis. However, the role of Piezo1 in fracture healing is not yet well characterized.

Age-associated callus senescent cells produce TGF-β1 that inhibits fracture healing in aged mice

open access: yesJournal of Clinical Investigation, 2022
Cellular senescence plays an important role in human diseases, including osteoporosis and osteoarthritis. Senescent cells (SCs) produce the senescence-associated secretory phenotype to affect the function of neighboring cells and SCs themselves.

Gait Analysis to Monitor Fracture Healing of the Lower Leg

open access: yesBioengineering, 2023
Fracture healing is typically monitored by infrequent radiographs. Radiographs come at the cost of radiation exposure and reflect fracture healing with a time lag due to delayed fracture mineralization following increases in stiffness.

Implantable Electrical Stimulation at Dorsal Root Ganglions Accelerates Osteoporotic Fracture Healing via Calcitonin Gene‐Related Peptide

open access: yesAdvancement of science, 2021
The neuronal engagement of the peripheral nerve system plays a crucial role in regulating fracture healing, but how to modulate the neuronal activity to enhance fracture healing remains unexploited.
