Vitamin D-deficient rats responded to i.p. injection of skin lipid extracts from DBP−/− mice with comparable, if not greater, increases in serum calcium compared to those administered DBP+/+ mouse skin extracts. Skin was obtained from mice immediately following UVB irradiation. Isolated lipid extracts were administered daily for 3 d. Two control groups were included that were administered vitamin D in place of skin extracts. Blood was collected for calcium measurement 24 h prior to the first injection and 24 h after the final injection (n = 2 rats per experimental group, n = 2 mice per extract [0.6 g skin total], ± SEM).
