Theriogenology 2024; 216:12-19. [PMID: 38147714 DOI: 10.1016/j.theriogenology.2023.11.031] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/27/2023] [Revised: 11/29/2023] [Accepted: 11/29/2023] [Indexed: 12/28/2023]
Abstract
Although somatic cell nuclear transfer (SCNT) is a critical component of animal cloning, this approach has several issues. We previously introduced the cytoplasm injection cloning technology (CICT), which significantly improves the quality and quantity of cloned embryos. This study examined the residual status of fused cytoplasmic organelles, such as the endoplasmic reticulum (ER) and lysosomes, in the CICT group during early embryo development. We found that extra-cytoplasmic organelles stained using the ER-Tracker™ Green dye and LysoTracker™ Deep Red probe were fused and dispersed throughout the recipient oocyte and were still visible in day 8 blastocysts. We screened for ER stress, autophagy, and apoptosis-related genes to elucidate the association between the added organelles and improved embryo quality in CICT-cloned embryos. We found that CHOP, ATF4, ATG5, ATG7, and LC3 genes showed non-significantly up- or downregulated expression between CICT- and in vitro fertilization (IVF)-derived embryos but showed significantly (p < 0.05) upregulated expression in SCNT-cloned embryos. Surprisingly, a non-significant difference in the expression of some genes, such as ATF6 and caspase-3, was observed between the CICT- and SCNT-cloned embryos. Our findings imply that compared to conventional SCNT cloning, CICT-derived cloned embryos with additional cytoplasm have much higher organelle activity, lower autophagy, lower rates of apoptosis, and higher embryo development rates.

Abstract
Cloned mammals can be achieved through somatic cell nuclear transfer (SCNT), which involves reprogramming of differentiated somatic cells into a totipotent state. However, low cloning efficiency hampers its application severely. Cloned embryos have the same DNA as donor somatic cells. Therefore, incomplete epigenetic reprogramming accounts for low development of cloned embryos. In this review, we describe recent epigenetic barriers in SCNT embryos and strategies to correct these epigenetic defects and avoid the occurrence of abnormalities in cloned animals.

Akagi S, Matsukawa K. Effects of Trichostatin A on the Timing of the First Cleavage and In Vitro Developmental Potential of Bovine Somatic Cell Nuclear Transfer Embryos.

Abstract
This study examined the relationship between the timing of the first cleavage and in vitro development of bovine somatic cell nuclear transfer (SCNT) embryos treated with trichostatin A (TSA). SCNT embryos were visually assessed at 22, 26, and 48 hours after activation. Each embryo with two or more distinct blastomeres was transferred into a microwell and cultured until day 7. Irrespective of TSA treatment, approximately half of the cleaved embryos were observed at 22 hours, and a significantly higher blastocyst formation rate was shown in the SCNT embryos cleaved at 22 hours than those cleaved at ≥26 hours. The blastocyst formation rate of TSA-treated embryos cleaved at 22 hours (80%) was slightly higher than that of the control embryos (70%). In addition, interferon-τ (IFN-τ) expression was significantly lower in control SCNT embryos and late-cleaving (>26 hours) TSA-treated embryos than in in vitro fertilized (IVF) embryos. However, a significant difference was not observed between TSA-treated SCNT embryos cleaved at 22 and 26 hours, and IVF embryos. These results suggest that TSA treatment has no influence on the timing of the first cleavage of SCNT embryos; however, it slightly improves the blastocyst formation rate and the expression level of IFN-τ in early-cleaving embryos.

The Resurrection of Mabrokan: Production of Multiple Cloned Offspring from Decade-Old Vitrified Tissue Collected from a Deceased Champion Show Camel. Animals (Basel) 2021; 11:ani11092691. [PMID: 34573657 PMCID: PMC8469105 DOI: 10.3390/ani11092691] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/12/2021] [Revised: 09/09/2021] [Accepted: 09/11/2021] [Indexed: 12/12/2022] Open
Abstract
Somatic cell nuclear transfer (SCNT) provides a unique opportunity to reproduce animals with superior genetics. Viable cell lines are usually established from tissues collected by biopsy from living animals in the SCNT program. In the present study, tissues were collected and preserved from a suddenly deceased champion camel. We established cell lines from these decade-old tissues and used them as nuclear donors. After 42 h of in vitro maturation, 68.00 ± 2.40% of oocytes reached the metaphase II (M II) stage while 87.31 ± 2.57% in vivo collected oocytes were matured at collection (p < 0.05). We observed a higher blastocyst formation rate when in vivo matured oocytes (43.45 ± 2.07%) were used compared to in vitro matured oocytes (21.52 ± 1.74%). The live birth rate was 6.45% vs. 16.67% for in vitro and in vivo matured oocytes, respectively. Microsatellite analysis of 13 camel loci revealed that all the SCNT-derived offspring were identical to each other and with their somatic cell donor. The present study succeeded in the resurrection of 11 healthy offspring from the decade-old vitrified tissues of a single somatic cell donor individual using both in vitro and in vivo matured oocytes.
