Bone and bone marrow disruption by endocrine‐active substances

Bone is a multifaceted dynamic tissue, involved in mobility, mineral metabolism, and mesenchymal or stromal and hematopoietic progenitor or stem cells breading. Recently, an endocrine role has been attributed to bone due to its ability to produce at least two hormones (osteocalcin and fibroblast growth factor 23) and to participate directly or indirectly in leptin, insulin, estrogens, and serotonin signaling; regulation; and action. Also, bearing in mind the enormous amounts of substances secreted by the different bone marrow cell types, it becomes understandable the contribution of bone tissue to systemic homeostasis. Besides, bone is a well‐known estrogen‐ responsive tissue, reacting to environmental influences. Thus, it has been coined as a critical target of environmental xenoestrogens, known as endocrine‐disrupting chemicals (EDCs). The exposure to EDCs results to disruption or imbalance of the systemic hormonal regulation of the skeleton including bone modeling and remodeling, local hormones, and cytokine or chemokine release. The present report highlights the harmful EDCs effects on bone tissue and provides up‐to‐date information of xenoestrogen action on proliferation, maturation, and homing of bone marrow inhabitants.
