Morphological differences in blastocoele cavity formation caused by culture with Pi. These photographs show embryos cultured for 48 h from the 2-cell stage in A) HECM-10 or B) HECM 10 + 1.25 µM Pi. Bar = 100 µm. Note that blastocoele cavities were clearly larger and more prominent in the embryos cultured with low levels of Pi.
