Fig 6. Relative expression levels of Bip (endoplasmic reticulum stress marker), Bax (pro-apoptosis marker), Bcl-2 (anti-apoptosis marker), and Oct-4 (pluripotency marker) were assessed by q-PCR in bovine SCNT blastocysts derived from renewal, nonrenewal, and supplementary groups.

Values with different superscripts differ significantly (P<0.05).
