Definition: Lipid-containing interstitial cell located in the alveolar septum (wall). The lipofibroblast transfers neutral lipid (tryglyceride) from the capillaries to the type II pneumocyte for the synthesis of surfactant phopholipids. It also synthesizes ECM proteins, such as collagen and elastin, and contains intermediate contractile filaments.
