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.

FAQs
Preserving tissue health helps maintain reliable observations of neuronal activity, blood flow, and neurovascular interactions. Excessive disturbance at the cranial surface could compromise the preparation and reduce experimental consistency. Careful control of the opening or thinning process therefore supports stable optical access while keeping the underlying brain suitable for repeated in vivo measurements.
A glass coverslip stabilizes the prepared region and creates a consistent optical interface for microscopy. It also helps limit infection and mechanical disturbance after the cranial surface has been opened or thinned. This protection is especially relevant when researchers plan repeated imaging sessions, because the preparation must remain sufficiently stable across time.
Bone Window Preparation can create either a controlled opening or a thinned region above the target area. Both approaches provide optical access, but they represent different ways of modifying the cranial surface while aiming to preserve tissue health. The selected form of preparation determines how the brain is accessed for imaging and how the site is stabilized afterward.
The preparation supports two-photon microscopy for observing neuronal activity, blood flow, and neurovascular interactions. Researchers can also combine optical access with electrophysiology or pharmacological manipulation. These combinations allow activity, vascular responses, and experimentally induced changes to be examined within related studies, broadening the information obtained from the same prepared brain region.
A typical workflow exposes the cranial surface, removes or thins bone above the selected target area, and may seal the site with a glass coverslip. Each stage contributes to controlled access, tissue protection, and preparation stability. The resulting site can then support in vivo optical measurements and, when planned, electrophysiological or pharmacological experiments.
A stabilized cranial preparation can enable repeated in vivo imaging of the same brain region over time. This longitudinal capability helps researchers follow changes in neuronal activity, blood flow, and neurovascular interactions rather than relying only on separate observations at individual time points. It is therefore useful for studying evolving brain function and disease-related processes.
