Title: | In Vivo Micro‐Computerized Tomography Tracking of Human Periodontal Ligament Stem Cells Labeled with Gold Nanocomplexes | Authors: | Zong, Chen BRONCKAERS, Annelies Vande Velde, Greetje Willems, Guy de Llano-Perula, Maria Cadenas |
Issue Date: | 2021 | Publisher: | WILEY | Source: | ADVANCED HEALTHCARE MATERIALS, , p. 2101133 (Art N° 2101133) | Abstract: | Gold nanocomplexes have been proposed as contrast agents for computerized tomography (CT) and cell tracking, which is especially useful in stem cell therapy. However, their potential for long-term in vivo cell detection is still unknown. This study proposes an optimized approach to labeling human periodontal ligament stem cells (hPDLSCs) with gold nanocomplexes to evaluate their detection with micro-CT after transplantation at four different rat tissues. The gold nanocomplexes of 0.05 mg mL(-1) do not affect cell viability nor osteogenic differentiation capacity, but render fluorescent and radiopaque hPDLSCs. Excellent linear correlation with the number of labeled cells is shown over a wide range (r = 0.99, P < 0.01), with a detection limit of approximate to 1.2 x 10(3) cells/mu L. In vivo, strong, and durable detection of transplanted labeled cells within 5 days at all investigated areas is seen by micro-CT and immunohistochemical assay. This approach confirms the potential of gold nanocomplexes in longitudinal in vivo cell tracking, which may facilitate their application in CT image-guided interventions commonly used in oromaxillofacial or systemic applications of stem cell therapy. | Notes: | Zong, C (corresponding author), Katholieke Univ Leuven, Dept Oral Hlth Sci Orthodont, B-3000 Leuven, Belgium.; Zong, C (corresponding author), Univ Hosp Leuven, Dent, B-3000 Leuven, Belgium. chen.zong@kuleuven.be |
