(2026) https://BioRender.com/4l6sgra . B , C Evaluation of carotid artery remodeling following carotid ligation and murine ADSC transplantation in C57 mice. B Representative EVG staining. C Quantification of neointima and media remodeling across 8 sections (1400 μm span) for CXCL14 + ADSC ( n = 5), CD55 + ADSC ( n = 6), and control ( n = 4) groups. D , E Evaluation of capillary formation (CD31) and ADSC engraftment (GFP) after carotid ligation and murine ADSC transplantation in C57 mice. D Representative images. Scale bar = 50 μm. E Quantification of CD31 + area in ligated arteries. Groups and n values as in ( C ). F – H Vascular remodeling in nude mice after ligation and human ADSC transplantation. F Representative images of Oil Red O staining. Scale bar = 100 μm. G Representative images of EVG staining. Groups and n values as in ( H ). H Quantification of neointima remodeling based on EVG staining (across 8 sections spanning 1400 μm) for CXCL14 + ADSC ( n = 6), CD55 + ADSC ( n = 5), and control ( n = 5) groups. I – L Immunofluorescence assessment of angiogenesis and human ADSC engraftment in nude mice. I , J Representative images of capillary formation (Isolectin B4), human endothelial cell formation (human CD31), and ADSC engraftment (GFP). Scale bar = 100 μm. K Quantification of Isolectin B4 positive area. L Quantification of human CD31-positive area. Groups and n values as in ( H ). M t-SNE visualization and evolutionary tree of lineages from CD55 + ADSC and CXCL14 + ADSC of PVAT to CD31 + endothelial cells of plaque from the same patient with carotid stenosis. Two-tailed two-way ANOVA followed by Tukey’s multiple comparisons test was used for analyses in ( C ) and ( H ). Two-tailed one-way ANOVA followed by Tukey’s multiple comparisons test was used for analyses in ( E , K , and L ). Data are presented as individual samples in ( C , E , H , and K – L ). Data are presented as the mean ± SD. CAS carotid artery stenosis, PVAT perivascular adipose tissue, ADSC adipose-derived stem cell, ns no significance. Source data are provided as a Source Data file.
Article Snippet: Experimental conditions included a serum-free negative control, a normal medium control, conditioned medium from CD55 + ADSCs (CD55 + ADSC-CM) and CXCL14 + ADSCs (CXCL14 + ADSC-CM), as well as CXCL14 + ADSC-CM containing 10 μM of the CXCR4 inhibitor Plerixafor octahydrochloride (HY-50912, MCE, China).
