Abstract

Evaluation of: Slotkin JR, Chakrabarti L, Dai HN, et al.: In vivo quantum dot labeling of mammalian stem cell and progenitor cells. Dev. Dyn. (2007) (Epub ahead of print) [1]. Quantum dots (QDs) show great promise for their use in cell tracking. In this recent study by Slotkin, et al., QDs are delivered to neural stem and progenitor cells in vitro and in vivo without having any effects on normal cell behavior. The results highlight a promising step towards the development of methodologies for tracking the role of stem cells in embryogenesis, tumorigenesis, organogenesis, tissue repair and regeneration. This evaluation will discuss the implications of the study and important future applications.
