This video describes the technique of aspirating bone marrow from iliac spine and smear preparation for biopsy. In the example, we perform bone marrow aspiration from an acute myeloid leukemia (AML) patient and examine the cells to check for measurable residual disease (MRD), an important prognostic biomarker.
FAQs
The key sensing step occurs in osteocytes embedded in the bone matrix. When loading changes tissue strain or fluid movement, these cells detect the mechanical condition and transmit signals to other bone cells. This signaling connects physical forces with downstream regulation of formation and resorption.
Bone strength depends on coordination between osteoblast-mediated formation and osteoclast-mediated resorption. Signals initiated by mechanically responsive osteocytes influence both activities as part of remodeling. This coordination links force sensing to ongoing adjustment of skeletal structure and function as mechanical conditions change over time during use.
Loading, including the mechanical demands associated with exercise, can engage signaling that supports skeletal adaptation. Disuse produces the opposite context: reduced mechanical input is associated with bone mass loss. This contrast shows why changes in physical use matter biologically and why mechanobiological principles are relevant to maintaining the skeleton as well as repairing it.
Fluid movement within the bone matrix is one of the mechanical conditions sensed by osteocytes, alongside tissue strain. Its importance is that osteocytes can convert these loading-related changes into signals that influence formation and resorption. In bioengineering, recognizing both cues helps frame how mechanical environments may affect skeletal adaptation and repair.
It guides bioengineers to consider how an implant or biomaterial scaffold will support skeletal integration and regeneration under mechanical conditions. The goal is not simply to provide a physical replacement, but to create a context compatible with the signaling and remodeling processes that maintain bone. These principles also inform strategies intended to achieve durable skeletal repair.
Applications extend from implant development and biomaterial scaffold design to mechanical stimulation strategies for injury and bone regeneration. These approaches use the mechanobiological relationship between loading, cellular signaling, formation, and resorption to support integration or repair. Their broader value lies in connecting skeletal biology with engineered interventions that aim for lasting structural function.
