Overview
This article presents a method for detecting the sequential incorporation of thymidine analogues (CldU and IdU) in adult mouse tissues, allowing for the quantification of two successive rounds of cell division. This technique is valuable for studying cell turnover in long-lived tissues, oncogenic transformation, and transit-amplifying cells.
