The Fate of Adipocytes after Nonvascularized Fat Grafting

Background: Clinical outcomes following fat grafting are variable and technique dependent, and it is unknown how the graft is revascularized. The authors recently observed that living and dead adipocytes can be differentiated not with hematoxylin and eosin staining but with immunohistochemistry for perilipin. Methods: The viability of cellular components (adipocytes, adipose stem/stromal/progenitor cells, vascular endothelial cells, and...
