TLDR TGFβ signaling prevents sebaceous gland cells from producing fats.
The study demonstrated that TGFβ signaling played a crucial role in regulating lipogenesis in human sebaceous gland cells by maintaining sebocytes in an undifferentiated state. Activation of the TGFβ pathway decreased the expression of lipogenic genes FADS2 and PPARγ through the TGFβ RII-Smad2 dependent pathway, thereby reducing lipid accumulation. Conversely, inhibition of TGFβ signaling led to increased lipid production. These findings highlighted the importance of TGFβ in sebocyte differentiation and suggested potential clinical applications for engineered skin grafts and treatments for sebaceous gland disorders.
