Large-Volume Fat Grafting: Identifying Risk Factors for Fat Necrosis

Catherine S. Chang et al.

Summary: This study investigated the incidence of fat necrosis after large-volume fat grafting and identified risk factors associated with fat necrosis. The study found that factors such as larger graft volumes, higher body mass index, concurrent implant exchange with fat grafting, and fat grafting after lumpectomy or mastectomy without preexpansion were associated with increased rates of fat necrosis. Additionally, radiation therapy may be linked to a higher rate of complications.

Effects of different oxygen tensions on differentiated human preadipocytes lipid storage and mobilisation

Bimit Mahat et al.

Summary: Hypoxia has complex effects on human adipocyte lipid storage and mobilisation functions, potentially favoring ectopic fat deposition. Acute hypoxia stimulates basal lipolysis, while chronic hypoxia decreases isoproterenol-stimulated lipolysis. Adipose tissue expansion may impair oxygen diffusion and cause hypoxia.

Exercise-Mediated Browning of White Adipose Tissue: Its Significance, Mechanism and Effectiveness

Wang-Jing Mu et al.

Summary: Adipose tissue is crucial in metabolism, with excessive expansion leading to obesity. Exercise can reduce fat mass and promote browning of white adipose tissue (WAT), benefiting metabolic balance. Various factors like reactive oxygen species, metabolites, and lipolysis can facilitate exercise-mediated browning of WAT.

Facial Rejuvenation with Concentrated Lipograft-A 12 Month Follow-Up Study

Lukas Prantl et al.

Summary: This study demonstrated that facial rejuvenation with concentrated fat graft can significantly improve the severity of wrinkles in patients and achieve high patient satisfaction postoperatively. The processed adipose tissue contained a significantly higher number of adipose-derived stem cells compared to unprocessed tissue.

Browning of White Adipocytes in Fat Grafts Associated With Higher Level of Necrosis and Type 2 Macrophage Recruitment

Tong Liu et al.

Summary: The study found that browning of adipocytes induced by fat transfer in mice is associated with higher levels of necrosis, elevated interleukin-6 levels, and an increase in type 2 macrophage profiles. These results suggest that post-grafting necrotic levels, elevated interleukin-6, and activated type 2 macrophage profiles are involved in promoting browning development in adipocytes induced by fat transfer.

Necroptosis in Macrophage Foam Cells Promotes Fat Graft Fibrosis in Mice

Xihang Chen et al.

Summary: The study revealed that macrophage necroptosis plays a critical role in fat graft fibrosis after transplantation, with the necroptotic macrophages activating collagen synthesis in fibroblasts through a paracrine mechanism. Inhibition of necroptosis in macrophages could potentially prevent fibrosis in fat grafts.
