Developmental Competence of Oocytes Selected for Handmade Cloning by Brilliant Cresyl Blue Staining

Group	Oocytes taken for IVF/reconstructs taken for HMC (n)	Cleavage n (%)	Blastocysts n (%)
IVF	506	339 (68.20±3.41)x	69 (14.63±4.05)a
HMC (BCB+)	418	393 (93.63±2.17)y	178 (43.41±2.54)b
HMC (BCB−)	247	227 (91.35±1.98)y	55 (22.74±1.76)c

Data from 15 trials.

Values are mean±standard error of the mean (SEM).

Values with different superscripts within the same column differ significantly (p<0.001).

Unstained oocytes were used as controls for IVF.

IVF, in vitro fertilization; HMC, handmade cloning; BCB, Brilliant Cresyl Blue.
