Unique cell composition in non-senescent, p16-senescent, and regressed
HHs. (A) Percentual distribution of CD31+, CD34+,
ERG+, PDPN+, and Ki67+ cells and
average vascular diameters in non-senescent, p16-senescent, and
regressed hemangiomas after HH classification. Comparison of
p16-senescent hemangiomas vs subgroup of interest by Wilcoxon rank-sum
test (*p<0.05, ***p<0.001). (B)
Age at resection and HH macroscopic size in non-senescent,
p16-senescent, and regressed hemangiomas. Comparison of p16-senescent
hemangiomas vs subgroup of interest by Wilcoxon rank-sum test (n.s.).
(C) Low and high magnification of CDK4, CATB, and CD68 in non-senescent,
p16-senescent, and regressed hemangiomas. Scale bar: 250 µm (low) and 20
µm (high). Asterisk (*) demarcates insulas of CATB-positive retained
hepatocytes in a non-senescent HH. (D) Percentual distribution of
CDK4+, CATB+, and CD68+ cells in
non-senescent, p16-senescent, and regressed hemangiomas after HH
classification. Comparison of p16-senescent hemangiomas vs subgroup of
interest by Wilcoxon rank-sum test (**p<0.01,
***p<0.001). Abbreviations: HH, hepatic
hemangioma; CDK4, cyclin-dependent kinase 4; CATB, catenin beta 1; n.s.,
not significant.
