Studies in the elderly suggest a reciprocal relation between increased marrow adiposity and bone loss, supporting basic research data indicating that osteoblasts and adipocytes share a common progenitor cell. However, whether this relation represents a preferential differentiation of stromal cells from osteoblasts to adipocytes or whether a passive accumulation of fat as bone is lost and marrow space increases with aging is unknown. To address this question and avoid the confounding effect of bone loss, we examined teenagers and young adults.
