Key result
Single cell transcriptomic analysis of murine heart valves demonstrated that interstitial cell subpopulations undergo changes in gene expression and cellular functions from postnatal day 7 to 30.
Why the study?
Heart valve cells mediate ECM remodeling during postnatal stratification, but phenotypic and transcriptional diversity of valve cells during development is largely unknown.
Single-cell transcriptomics reveals that while endothelial and immune cells remain stable, interstitial cells in mouse heart valves undergo significant transcriptional changes during postnatal maturation.

Interstitial cell remodeling in murine valves is hypothesis-generating; leaves open human translation or therapeutic relevance.
Hulin et al. (2019) studied Postnatal heart valve remodeling. Postnatal development (P7 vs P30) was evaluated on Transcriptomic analysis of single cells from postnatal day 7 and 30 murine aortic and mitral heart valves. Single cell transcriptomic analysis of murine heart valves demonstrated that interstitial cell subpopulations undergo changes in gene expression and cellular functions from postnatal day 7 to 30.
