We have developed a technique to sample the preimplantation embryo, which may, in the future, be applied to prenatal diagnosis of genetic disease. Using micromanipulation, we aspirated a single blastomere from 4-cell mouse embryos. This procedure had no effect on in vitro development; 98% of control and 94% of biopsied embryos reached the blastocyst stage after 48 h in culture. Furthermore, after transfer to pseudopregnant recipient mice, the rate of fetal development of biopsied embryos was not significantly different from control embryos, although implantation rate was significantly reduced (mean +/- SD: biopsied 53.1 +/- 4.0, control 81.8 +/- 8.4, p less than 0.001). For the first time we have produced monolayer cell cultures derived from single preimplantation blastomeres. Individual biopsied blastomeres were cultured in vitro on different extracellular matrix components. Significantly greater cell proliferation was obtained in wells coated with fibronectin (FN), laminin (LN), and a complex of laminin and nidogen (LNC) than in a less specific matrix of swine skin gelatin (SSG). Mean (+/- SE) cell nuclei number per well after 6 days in culture was 6.4 +/- 2.1, 11.9 +/- 1.5, 19.8 +/- 2.9, and 20.9 +/- 2.6 in wells coated with SSG, LN, FN, and LNC respectively.
