Ferret cloning using different methods for nuclear transfer and somatic donor cell types

Method of nuclear transfer	Donor cell (type)	Nuclear transfers (no. embryos transferred)	Embryo transfers (no. recipients)	3-week implantation (%)	3-week fetal development (%)	Birth rate (%)
Microinjection	Fibroblast	460	15	7.2 (25/349)	3.4 (12/349)	0 (0/111)
	Cumulus cell	391	15	14.2 (44/310)	4.2 (13/310)	1.2 (1/81) ^a
Cell Fusion	Fibroblast	430	14	5.5 (18/326)	3.1 (10/326)	0.96 (1/104) ^b
	Cumulus cell	487	14	4.3 (16/375)	3.2 (12/375)	1.8 (2/112) ^c
