Abstract

We developed a reporter system that can be used in a dual manner in visualizing mature osteoblast formation. The system is based on a helper-dependent adenoviral vector (HDAdV), in which a fluorescent protein, Venus, is expressed under the control of the 19-kb human osteocalcin (OC) genomic locus. By infecting human and murine primary osteoblast (POB) cultures with this reporter vector, the cells forming bone-like nodules were specifically visualized by the reporter. In addition, the same vector was utilized to efficiently knock-in the reporter into the endogenous OC gene of human induced pluripotent stem cells (iPSCs), by homologous recombination. Neural crest-like cells (NCLCs) derived from the knock-in reporter iPSCs were differentiated into osteoblasts forming bone-like nodules and could be visualized by the expression of the fluorescent reporter. Living mature osteoblasts were then isolated from the murine mixed POB culture by fluorescence-activated cell sorting (FACS), and their mRNA expression profile was analyzed. Our study presents unique utility of reporter HDAdVs in stem cell biology and related applications.
