Table 1.

In vitro development of ZFREs reconstructed with BM-MSC or fibroblasts as nuclear donors

Groups	ZFREs	No. of embryos (wells)^*	No. of cleaved embryos (%)	Blastocyst production
Groups	ZFREs	No. of embryos (wells)^*	No. of cleaved embryos (%)	No.	% per embryo	% per ZFRE
AF	4527	1509	3875 (85.6)^a	492	32.6^a	10.9^a
MSC	3432	1144	3095 (90.2)^b	622	54.4^b	18.1^b

Notes:

^a,b

Values with different superscripts in a column are significantly different (Fisher’s exact test p<0.05).

Embryo aggregation was performed and each well contained three ZFREs.

Abbreviations: ZFREs, zona-free reconstructed embryos; BM-MSCs, bone marrow–derived mesenchymal stem cells; AF, adult fibroblasts; MSC, mesenchymal stem cell.
