AbstractHuman airways contain specialized rare epithelial cells including CFTR-rich ionocytes that regulate airway surface physiology and chemosensory tuft cells that produce asthma-associated inflammatory mediators. Here, using a lung cell atlas of 311,748 single cell RNA-Seq profiles, we identify 687 ionocytes (0.45%). In contrast to prior reports claiming a lack of ionocytes in the small airways, we demonstrate that ionocytes are present in small and large airways in similar proportions.

Correction to: Nature Aging https://doi.org/10.1038/s43587-023-00373-6, published online 9 March 2023. Following publication, the authors were alerted to a potential duplication in two of the micrographs shown in the paper. After a detailed review, it appears that two probes (Hspa1a and Pecam1) in an RNA in situ hybridization experiment were unintentionally swapped in the representative images shown in Figs. 5c and 8b of the published manuscript.

AbstractSingle-cell RNA-seq data have provided new insights into intracellular and intercellular processes. Because multiple processes are active in each cell simultaneously, such as its cell type program, differentiation, the cell cycle, and environmental responses, their respective signals can confound one another, requiring methods that can separate and filter different complex biological signals.

AbstractOver a lifetime, hematopoietic stem cells (HSCs) adjust their lineage output to support age-aligned physiology. In model organisms, stereotypic waves of hematopoiesis have been observed corresponding to defined age-biased HSC hallmarks. However, how the properties of hematopoietic stem and progenitor cells change over the human lifespan remains unclear.

AbstractGermline BRCA1 mutation carriers face a high breast cancer risk; however, the underlying mechanisms for this risk are not completely understood. Using a new genetically engineered mouse model of germline Brca1 heterozygosity, we demonstrate that early tumor onset in a Brca1 heterozygous background cannot be fully explained by the conventional ‘two-hit’ hypothesis, suggesting the existence of inherent tumor-promoting alterations in the Brca1 heterozygous state.
