Abstract
Considerable advancements have recently been achieved in porcine somatic cell nuclear transfer (SCNT), but the efficiency remains low. Donor cell size might play an important role in SCNT, but its effects in pigs remain unclear. This study aimed to evaluate the efficiency of porcine SCNT by selecting donor cells of suitable size. Porcine fetal fibroblasts (PFFs) were divided into three groups, group S (small, d ≤ 13 μm), group M (medium, 13 μm<d ≤ 18 μm), and group L (large, d > 18 μm), and their biological characteristics were analyzed. Next, SCNT was performed using PFFs of different sizes to evaluate the developmental potential of reconstructed embryos. The data showed that PFFs in groups S, M and L accounted for 17.5%, 47.7% and 34.8% of cells, respectively. Morphologically, cells in group S exhibited clear and regular cell membranes and nuclei, whereas cells in groups M and L displayed varying degrees of cell membrane protuberance, karyo-pyknosis, autophagy and mitochondrial abnormalities. In addition, the growth status and proliferation capabilities of cells in group S were significantly better than those of group M and group L. The percentage of cells at G0/G1 in group S and M were significantly greater than group L. The senescence rate of group S was lower than group M and group L. The apoptosis rate of group S was significantly lower than that of group L but comparable to that of group M . The cleavage rate of group S was also significantly greater than that of group M but comparable to that of group L . The blastocyst rate of group S was significantly greater than that of group M and group L. The blastocyst cell numbers of group S were also significantly greater than those of group M and group L. These findings suggested that small PFFs with a diameter of less than 13 μm are more suitable donor cells for SCNT in pigs.Abbreviations: DMEM: Dulbecco's modified Eagle's medium; FBS: Fetal bovine serum; PBS: Phosphate buffer saline; PFFs: Porcine fetal fibroblast cells; SCNT: Somatic cell nuclear transfer.

Abstract
The present study aimed to detect the expression of β-galactosidase during long-term cultured goat skin fibroblasts and investigate the effects of donor goat age, sex, and cell passage on senescence and the effects of donor cell passage on in vitro development of nuclear transfer embryos. The results showed that, in the same cell passage, more β-galactosidase-positive cells were detected in cells from older donors than younger donors. Irrespective of the donor age, the number of positive cells was higher in later passages from passages 20 to 50. In the same passage from 20 to 50, the β-galactosidase-positive rate was higher in cells from 5-yr female goat than 5-yr male goat. Using fibroblasts from male goats at various passages as donor cells, reconstructed embryos had similar fusion and cleavage rates, but the blastocyst rate was higher for cells at passages 10 and 20 than passage 30. In conclusion, donor goat age and cell passage had significant effects on the β-galactosidase-positive rate; also, cells from 5-yr female goat had a higher β-galactosidase-positive rate than those from 5-yr male goat, and the donor cell passage affected the developmental potential of nuclear transfer embryos.
