2. Figure 1
Laser scanning confocal (A, B) and differential interference contrast (C) images of cleavage-stage human embryos showing normal cleavage (A), fragmentation and degeneration (B), and type 4 fragments (C). Three normal mitotic spindles are visible in A, and the cytoskeletal structure in the interphase cells is organized. By contrast, the fragmented embryo in B shows disorganized cytoskeletal structure—one abnormal nucleus and one cell in anaphase. (C) Predominantly large fragments (type 4) are interspersed among blastomeres of varying sizes. Green stain is tubulin, and red stain is DNA. Immunofluorescence staining methods are described by Alikani et al. (7, 9).
