Abstract (original English)

This study was aimed to evaluate the effect of (124)I-labeling with hexadecyl-4-iodobenzoate (HIB) on gene expression related to cell cycle, DNA repair, transcription, proliferation and differentiation of adipose-derived stem cells (ADSCs). [(124)I]HIB showed high labeling efficiency with ADSCs (51.3±1.3%, 0.3-2.0 Bq/cell) and there is no morphological change of ADSCs. In the microarray analysis of gene expression pattern, differences were not observed between non-labeled and [(124)I]HIB-labeled ADSCs. We demonstrated that (124)I-labeling with HIB did not affect the biological properties of ADSCs.
