    Infantile hemangioma (IH) is the most common benign vascular tumor in infants, characterized by rapid proliferation followed by spontaneous involution.

  • 2

    Propranolol is established as the first-line therapy for high-risk IH, achieving significant resolution rates in treated patients.

  • 3

    Single-cell RNA sequencing has revealed cellular heterogeneity in IH, identifying specific subpopulations that contribute to its biphasic behavior.

  • 4

    Macrophages, mast cells, and telocytes in the stromal microenvironment influence IH progression and response to propranolol treatment.

  • 5

    Understanding the cellular mechanisms of IH and propranolol action can inform treatment strategies and improve patient outcomes.
