The Signal How Urist, Reddi, and Wozney Identified the Molecules That Instruct Bone to Form — and Built the First Biologic That Could Deliver Them Bone does not simply grow. It is instructed to grow — by signals embedded in its own matrix, waiting to be released, decoded, and put to work. Introduction Part One of this series established that bone marrow contains a rare population of progenitor cells capable of forming bone, cartilage, and the structural scaffolding of the

The Cell How Friedenstein, Owen, and Caplan Discovered — and Redefined — the Cells Behind Bone Regeneration Bone marrow is not merely a factory for blood. It harbors, in quiet reserve, the precursor cells capable of rebuilding the entire skeleton. Introduction Every clinical advance in osteobiologics — from demineralized bone matrix to bone marrow aspirate concentrate to today's skeletal stem cell therapies — rests on a single insight: bone marrow contains a rare populati

Understanding the Economics of Tissue Banks In the first article in this series, we followed the journey of a donated tissue—from donor consent through recovery, testing, processing, and distribution. The goal was to answer a simple question: If the tissue is donated, why does it cost anything at all? The answer is that hospitals are not paying for the tissue itself. They are paying for the infrastructure required to make that tissue safe, compliant, traceable, and usable in

The Long Journey from Tissue Donation to the Operating Room Every year, thousands of patients receive life-changing procedures using donated human tissue. Bone grafts help achieve spinal fusion. Tendons restore knee stability. Placental tissues support wound healing. Yet one question inevitably arises whenever allografts enter the conversation: If the tissue was donated, why does it cost so much? The answer is both simple and surprisingly complex. Human tissue itself is never

A Clinically Pragmatic Review of the Evidence Key Takeaways Bone marrow aspirate functions as a biologic component within a fusion construct , with its contribution dependent on technique, biologic dose, and compatibility with the graft material used. Cell dose and retention matter. Variability in historical outcomes may reflect dilution, delivery, and early harvesting limitations rather than an absence of marrow-derived biologic effect. Clinical and translational studies su

For decades, every biology textbook drilled into us that mitochondria are the “powerhouse of the cell.” But a new Scientific American piece argues that’s misleading—and maybe even harmful to our understanding.
