Fig. 1. Constitutive PtdIns(3,4,5)P3 synthesis in preimplantation embryos. Confocal sections of mouse embryos expressing GFP-PHGRP1. The following stages are shown (left to right, top to bottom): one-cell, two-cell, four-cell, compacted eight-cell, 16-cell morula and early blastocyst. Embryos were cultured at high density (one embryo/µl). Confocal images are representative of at least 12 similar observations. Scale bar: 20 µm.
