Preimplantation development of cloned sheep embryos derived from KDM4D protein-treated cells

Groupsa	No. of reconstructed embryosb	No. of cleaved (%, mean ± SEM)	No. of blastocysts (%, mean ± SEM)	Total cell number in blastocyst (mean ± SEM)
C-NT	169	157 (92.6 ± 3.7)	17 (11.3 ± 3.0)c	83.0 ± 8.1c
T-NT	170	162 (95.3 ± 2.0)	31 (19.2 ± 1.2)d	124.3 ± 17.0d

Cleavage percentage: no. of cleaved/no. of reconstructed embryos. Blastocyst percentage: no. of blastocysts/no. of cleaved

^aC-NT, embryos cloned from cells without KDM4D treatment; T-NT, embryos cloned from KDM4D-treated cells

^bTotal numbers of embryos from 4 replicates

^c,dWithin a row represent significant difference between groups (P < 0.05). The data were statistically analyzed by Student’s two-tailed t test
