摘要

The aim of this study is to establish a recapitulation system of human endochondral ossification as a paradigm of developmental engineering. Chondrocytes were isolated from the epiphyseal cartilage of the supernumerary digits of infants with polydactyly. In vivo studies showed that implanted chondrocytes exhibited cartilaginous regeneration over a short period of time and subsequent endochondral ossification with a marrow cavity. Tracing studies revealed that cells of donor origin at the periphery of the cartilage migrated into the center of the cartilage and transformed into osteoblasts, adipocytes, and endothelial cells. Bone marrow was formed through anastomosis with the recipient endothelial system at 13 weeks, and from the migration of recipient hematopoietic cells at 50 weeks. This study provides a human endochondral ossification model system with transdifferentiation of the donor cells at the periphery of the cartilage. J. Cell. Physiol. 230: 1376-1388, 2015.
