Where this comes from

Abstract

Detoxification of endogenous aldehydes is critical for preserving genomic integrity in hematopoietic stem cells. In this issue, Kamimae-Lanning et al.<sup>1</sup> show that excess formaldehyde can drive clonal hematopoiesis through attrition of blood-forming progenitors, accelerating neutral drift in the absence of known genetic drivers of positive selection.
