Table 2. In vivo development of cloned embryos treated with TSA.

Group	No. surrogate	No. pregnancy (%) a	No. delivery	No. offspring (mean) b	No. offspring alive (%) c
NT-CON	10	4 (40.00)	3	8 (2.67)	3 (37.50)
NT-TSA	5	3 (60.00)	2	7 (3.50)	6 (85.71)

After treatment with TSA, in vivo development of cloned embryos was improved.

^aThe pregnant rate was based on the surrogate number and one pregnant surrogate in each group was used for fetus examination.

^bThe number of offspring was adjusted for the delivery number.

^cThe number of alive offspring was based on the offspring number.
