The protocol describes a novel murine femur window chamber model that can be used to track movement of cells in the femoral bone marrow in vivo. Intravital multiphoton fluorescence microscopy is used to image three components of the femoral bone marrow (vasculature, collagen matrix, and neutrophils) over time.

One constraint of preclinical research in the field of bone repair is the lack of experimental control over the local mechanical environment within a healing bone lesion. We report the design and use of an external fixator for bone repair with the ability to change fixator stiffness in vivo.

During most eukaryotic translation processes, the small 40S ribosome subunit scans an mRNA from its 5' end until it encounters the first start AUG codon. The large 60S ribosomal subunit then joins the smaller one to initiate protein synthesis. The location of the translation initiation is largely determined by the nucleotides near the start codon as there may be multiple translation initiation sites present on the mRNA. Marilyn Kozak discovered that the sequence RCCAUGG (where R stands for...

Bones of the Lower Limb: Femur and Patella

The femur is the body's longest and strongest bone spanning the thigh region. Its head articulates with the acetabulum of the hip bone to form the hip joint. A minor indentation on the medial side of the femoral head, called the fovea capitis, serves as the site of attachment for the ligament of the head of the femur. This weak ligament spans the femur and acetabulum and supports the hip joint. The narrowed region below the head is the neck of the femur. The inclination angle between the neck...

Source: Danielle N. Beatty and Taylor D. Sparks, Department of Materials Science and Engineering, The University of Utah, Salt Lake City, UT Differential scanning calorimetry (DSC) is an important measurement to characterize thermal properties of materials. DSC is used primarily to calculate the amount of heat stored in a material as it heats up (heat capacity) as well as the heat absorbed or released during chemical reactions or phase changes. However, measurement of this heat can also lead to...
FAQs
Image contrast determines which femoral features become most distinguishable. X-ray contrast supports visualization of overall bone shape, while computed tomography reconstructs cross-sectional anatomy. Magnetic resonance imaging provides tissue-specific signals that can reveal marrow-related differences, and dual-energy X-ray absorptiometry produces estimates of bone mineral density. Matching contrast behavior to the research question improves the relevance of the scan.
Computed tomography is more informative when the investigation requires cross-sectional anatomy rather than only the femur’s overall shape. Radiography uses X-rays to provide a broad structural view, whereas computed tomography reconstructs anatomy across sections. This distinction can help investigators examine femoral structure in greater anatomical detail when a two-dimensional overview does not answer the specific question.
Magnetic resonance imaging and dual-energy X-ray absorptiometry measure different aspects of the femur. Magnetic resonance imaging detects tissue-specific signals, making it suited to questions involving tissue contrast such as marrow visualization. Dual-energy X-ray absorptiometry estimates bone mineral density, supporting assessment of mineral loss. Their outputs should therefore be interpreted according to whether the study focuses on tissue or mineral content.
Selection requires balancing the desired visualization against practical constraints. Important considerations include spatial detail, acquisition time, cost, and radiation exposure. A method that offers useful structural information may not be the best choice if its acquisition demands or exposure are inappropriate for the study. The preferred scan is the one whose contrast and practical profile fit the investigation’s specific objective.
Begin by identifying whether the study concerns overall shape, cross-sectional anatomy, tissue-specific features, or bone mineral density. Next, compare the techniques that provide those forms of contrast, then weigh spatial detail, acquisition time, cost, and radiation exposure. Recording the selection rationale and applying it consistently helps align the scan with the research question and supports comparable measurements.
Standardized selection makes repeated femoral measurements more comparable across time and between studies. Using a consistent approach preserves the relationship between the research question, the imaging contrast, and the measured outcome. This is especially important when tracking structural change, marrow-related visualization, or mineral loss, because inconsistent technique choices can complicate interpretation of differences observed during longitudinal assessment.
