5 Key Takeaways

• 1

  A single-cell proteomics workflow revealed distinct vascular cell states in Marfan syndrome, highlighting aneurysm-related changes in the aortic wall.

• 2

  Researchers analyzed nearly 5,000 cells from aortic roots of wild-type and Fbn1C1041G/+ mice, identifying major aortic cell types.

• 3

  The study identified 16 cell groups, including seven smooth muscle cell subtypes, revealing heterogeneity not captured by bulk analysis.

• 4

  Altered smooth muscle cell states were more prevalent in Marfan tissue, with specific markers indicating shifts during aneurysm development.

• 5

  Integration of proteomic and transcriptomic data identified additional Marfan-associated cell states, emphasizing the need for functional studies.
