Fig. 2. Immunofluorescence confocal microscopy of E-cadherin (A-H) and JAM-1 (I-P) staining patterns during preimplantation development. The stages are unfertilized eggs (UF) and embryos at two-cell (2C), four-cell (4C), precompact eight-cell (8C), compact eight-cell (C8C), morula (Mor), early blastocyst (EB) and late blastocyst (LB) stages. Bar, 20 µm.
