Abstract
Pancreatic β cells are responsible for insulin secretion and are important for glucose regulation in a healthy body and diabetic disease patient without prelabeling of islets. While the conventional biomarkers for diabetes have been glucose and insulin concentrations in the blood, the direct determination of the pancreatic β cell mass would provide critical information for the disease status and progression. By combining fluorination and diversity-oriented fluorescence library strategy, we have developed a multimodal pancreatic β cell probe PiF for both fluorescence and for PET (positron emission tomography). By simple tail vein injection, PiF stains pancreatic β cells specifically and allows intraoperative fluorescent imaging of pancreatic islets. PiF-injected pancreatic tissue even facilitated an antibody-free islet analysis within 2 h, dramatically accelerating the day-long histological procedure without any fixing and dehydration step. Not only islets in the pancreas but also the low background of PiF in the liver allowed us to monitor the intraportal transplanted islets, which is the first in vivo visualization of transplanted human islets without a prelabeling of the islets. Finally, we could replace the built-in fluorine atom in PiF with radioactive 18F and successfully demonstrate in situ PET imaging for pancreatic islets.

Abstract
Selection of a specific neural stem/progenitor cells (NSPCs) has attracted broad attention in regenerative medicine for neurological disorders. Here, we report a fluorescent probe, CDg13, and its application for isolating strong neurogenic NSPCs. In comparison to the NSPCs isolated by other biomarkers, CDg13-stained NSPCs showed higher capability to differentiate into neurons. Target identification revealed that the fluorescence intensity of the probe within cells is inversely proportional to the expression levels of mouse and human Abcg2 transporters. These findings suggest that low Abcg2 expression is a biomarker for neurogenic NSPCs in mouse brain. Furthermore, CDg13 can be used to isolate Abcg2low cells from heterogeneous cell populations.
