Mechanical response tissue analyzer for estimating bone strength [PDF]

open access: yes
One of the major concerns for extended space flight is weakness of the long bones of the legs, composed primarily of cortical bone, that functions to provide mechanical support.

Differential Phase Contrast Imaging to Predict MSC Immune Function

open access: yesAdvanced Healthcare Materials, EarlyView.
This work employs quantitative differential phase contrast (qDPC) imaging technique to non‐invasively extract morphological features from live Mesenchymal Stromal Cells (MSCs) for single cell prediction on cell immunomodulatory capacity. This work establishes a foundation for scalable, non‐destructive monitoring of MSCs immunomodulatory capacity ...

An Organ‐on‐Chip Platform for Strain‐Controlled, Tissue‐Specific Compression of Cartilage and Mineralized Osteochondral Interface to Study Mechanical Overloading in Osteoarthritis

open access: yesAdvanced Healthcare Materials, EarlyView.
A mechanically active OsteoChondral Unit (OCU)‐on‐Chip platform mimicking the OCU's functional anatomy and the strain gradient across the osteochondral interface is presented. Upon compartment‐specific hyperphysiological compression, the model replicates mechanisms observed in osteoarthritis (OA) progression, such as calcium crystal accumulation ...

State of the mineral component of rat bone tissue during hypokinesia and the recovery period [PDF]

open access: yes
Experiments were conducted on young growing rats. Hypokinesia lasting from 20 to 200 days caused retarded gain in weight and volume of the femur and delayed development of the cortical layer of the diaphysis.

Therapeutic Implants: Mechanobiologic Enhancement of Osteogenic, Angiogenic, and Myogenic Responses in Human Mesenchymal Stem Cells on 3D‐Printed Titanium Truss

open access: yesAdvanced Healthcare Materials, EarlyView.
This study investigates a synergistic effect between 3D‐printed surface features and mechanical micro‐strain in enhancing the osteogenic, angiogenic, and myogenic responses of human mesenchymal stem cells (hMSCs). Load‐induced mechanotransduction, facilitated by the implant's architectural design, significantly amplifies hMSC differentiation.

Space medicine considerations: Skeletal and calcium homeostasis [PDF]

open access: yes
Based on the information obtained from space missions, particularly Skylab and the longer Salyut missions, it is clear that bone and mineral metabolism is substantially altered during space flight.
