Regenerative Medicine: Conjugated Polymer Nanodots as Ultrastable Long-Term Trackers to Understand Mesenchymal Stem Cell Therapy in Skin Regeneration (Adv. Funct. Mater. 27/2015).

On page 4263, D. Ding, B. Liu, K. Li, and co‐workers report a class of conjugated polymer (CP) nanodots as fluorescent trackers for long‐term in vivo tracking of transplanted mesenchymal stem cells (MSCs) to understand the mechanism in regenerative medicine. The transplanted MSCs with CP nanodot labeling could be clearly observed at a single cell level in the regenerated tissues collected from wound‐bearing mice after 3 weeks, identifying that the paracrine signaling is the primary contribution of MSCs in promoting skin regeneration.
