Incorporation of [14C]fatty acid into glycerolipids during [14C]acetate labeling of wild-type and PLDζ developing embryos. A and C, [14C]fatty acid into TAG, DAG, and PC in wild-type embryos. B and D, [14C]fatty acid into TAG, DAG, and PC in PLDζ embryos (SD, n = 3, time points: 3, 6, 10, 30, 60, 180 min). Significant differences (T test, P < 0.05) between PLDζ (A) and wild type (B) were limited to differences in TAG and differences in DAG at 180 min, as indicated with two asterisks.
