[PMID: 37998748 PMCID: PMC10670481 DOI: 10.3390/cimb45110571] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/24/2023] [Revised: 11/10/2023] [Accepted: 11/13/2023] [Indexed: 11/25/2023] Open
Abstract
Although the efficiency of cloning remains very low, this technique has become the most reliable way to produce transgenic pigs. However, the high rate of abnormal offspring such as an enlarged tongue lowers the cloning efficiency by reducing the early survivability of piglets. Thus, the present study was conducted to identify the characteristics of the enlarged tongue from cloned piglets by histologic and transcriptomic analysis. As a result, it was observed that the tissues from enlarged tongues (n = 3) showed isolated and broken muscle bundles with wide spaces while the tissues from normal tongues (n = 3) showed the tight connection of muscle bundles without space by histological analysis. Additionally, transmission electron microscopy results also showed the formation of isolated and broken muscle bundles in enlarged tongues. The transcriptome analysis showed a total of 197 upregulated and 139 downregulated genes with more than 2-fold changes in enlarged tongues. Moreover, there was clear evidence for the difference between groups in the muscle system process with high relation in the biological process by gene ontology analysis. The analysis of the Kyoto Encyclopedia of Gene and Genomes pathway of differentially expressed genes indicated that the pentose phosphate pathway, glycolysis/gluconeogenesis, and glucagon signaling pathway were also involved. Conclusively, our results could suggest that the abnormal glycolytic regulation may result in the formation of an enlarged tongue. These findings might have the potential to understand the underlying mechanisms, abnormal development, and disease diagnosis in cloned pigs.

[PMID: 30324161 PMCID: PMC6182226 DOI: 10.12717/dr.2018.22.3.245] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/19/2018] [Revised: 08/16/2018] [Accepted: 09/03/2018] [Indexed: 11/18/2022]
Abstract
To improve survival rates of vitrified pig oocytes, the treatment of cytoskeletal
stabilizer on an appropriate time is one of the possible approaches. However,
the exact treatment timing and effect of cytoskeletal stabilizer such as
cytochalasin B (CB) is not well known during oocyte vitrification procedures.
Thus, the present study was conducted to determine optimal treatment timing of
CB during vitrification and warming procedures. In experiment 1, the survival
rates of the post-warming pig oocytes were analyzed by fluorescein diacetate
(FDA) assays with 4 classifications. In results, post-warming oocytes showed
significantly (p<0.05) decreased number of alive oocytes
(31.8% vs. 86.4%) compared to fresh control. In detail, the significant
difference (p<0.05) was found only in strong
fluorescence (18.2% vs. 70.5%) not in intermediate fluorescence groups (13.6%
vs. 15.9%). In experiment 2, CB was treated before (CB-Vitri) and after
(Vitri-CB) vitrification. In results, group of Vitri-CB showed significantly
(p<0.05) higher (91.6%) survival rates compared to
group of CB-Vitri (83.7%), significantly (p<0.05) and
comparable with group of Vitri Control (88.7%) by morphological inspection. In
FDA assay results, group of Vitri-CB showed significantly
(p<0.05) higher (44.2%) survival rates compared to
groups of CB-Vitri (36.7%) and Vitri Control (35.1%). In conclusion, the
increased survival rates of post-warming pig oocyte treated with Vitri-CB method
are firstly described here. The main finding of present study is that the CB
treatment during recovery could be helpful to refresh the post-warming pig
oocyte resulting its improved survival rates.

Establishment and identification of cell lines from type O blood Korean native pigs and their efficiency in supporting embryonic development via somatic cell nuclear transfer. J Vet Sci 2018; 19:492-499. [PMID: 29486531 PMCID: PMC6070591 DOI: 10.4142/jvs.2018.19.4.492] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/10/2017] [Revised: 07/28/2017] [Accepted: 02/02/2018] [Indexed: 11/20/2022] Open
Abstract
Due to their similarities with humans in anatomy, physiology, and genetics miniature pigs are becoming an attractive model for biomedical research. We aim to establish and evaluate blood type O cells derived from Korean native pig (KNP), a typical miniature pig breed in Korea. Ten cell lines derived from 8 KNP piglets and one adult female KNP (kidney and ear tissues) were established. To confirm the presence of blood type O, genomic DNA, fucosyltransferase (FUT) expression, and immunofluorescence staining were examined. Additionally, fluorescence-activated cell sorting and somatic cell nuclear transfer were performed to investigate the normality of the cell lines and to evaluate their effectiveness in embryo development. We found no significant bands corresponding to specific blood group A, and no increase in FUT expression in cell lines derived from piglets No. 1, No. 4, No. 5, No. 8, and the adult female KNP; moreover, they showed normal levels of expression of α 1,3-galactosyltransferase and cytidine monophosphate-N-acetylneuraminic acid hydroxylase. There was no significant difference in embryo development between skin and kidney fibroblasts derived from the blood type O KNPs. In conclusion, we successfully established blood type O KNP cell lines, which may serve as a useful model in xenotransplantation research.

[PMID: 28785737 PMCID: PMC5532308 DOI: 10.12717/dr.2017.21.2.157] [Citation(s) in RCA: 19] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/01/2017] [Revised: 05/04/2017] [Accepted: 05/08/2017] [Indexed: 11/17/2022]
Abstract
One of the reasons to causing blood coagulation in the tissue of xenografted
organs was known to incompatibility of the blood coagulation and
anti-coagulation regulatory system between TG pigs and primates. Thus,
overexpression of human CD73 (hCD73) in the pig endothelial cells is considered
as a method to reduce coagulopathy after pig-to-non-human-primate
xenotransplantation. This study was performed to produce and breed transgenic
pigs expressing hCD73 for the studies immune rejection responses and could
provide a successful application of xenotransplantation. The transgenic cells
were constructed an hCD73 expression vector under control porcine Icam2 promoter
(pIcam2-hCD73) and established donor cell lines expressing hCD73. The numbers of
transferred reconstructed embryos were 127 ± 18.9. The pregnancy and delivery
rate of surrogates were 8/18 (44%) and 3/18 (16%). The total number of delivered
cloned pigs were 10 (2 alive, 7 mummy, and 1 died after birth). Among them,
three live hCD73-pigs were successfully delivered by Caesarean section, but one
was dead after birth. The two hCD73 TG cloned pigs had normal reproductive
ability. They mated with wild type (WT) MGH (Massachusetts General Hospital)
female sows and produced totally 16 piglets. Among them, 5 piglets were
identified as hCD73 TG pigs. In conclusion, we successfully generated the hCD73
transgenic cloned pigs and produced their litters by natural mating. It can be
possible to use a mate for the production of multiple transgenic pigs such as
α-1,3-galactosyltransferase knock-out /hCD46 for xenotransplantation.
