5-Ethynyl-2’-deoxyuridine (EdU) is a thymidine analog used to label newly synthesized DNA, enabling precise detection of cell proliferation via click chemistry. Unlike traditional methods such as BrdU incorporation, EdU does not require DNA denaturation, preserving cellular integrity and improving detection sensitivity. In neuroscience, EdU is extensively used to monitor neurogenesis, particularly in studies of brain development, injury response, and neurodegenerative disease models. Its compatibility with multiplexed imaging makes it a powerful tool for tracking neural stem cell dynamics and evaluating regenerative therapies.
