Derivation of Two New Human Embryonic Stem Cell Lines from Nonviable Human Embryos

Figure 4

Comparison of embryo morphology on ED5 and ED6. Morphological categories on ED5 and ED6 are shown by percentage in stacked columns. Numbers indicate the number of embryos in each category. HB = hatching blastocyst, B = blastocysts, EB = early blastocyst, comp = compacted, MC = multicell, 1C = one cell, deg = degenerated.
