Aberrant profile of gene expression in cloned mouse embryos derived from donor cumulus nuclei

et al. 2006

Somatic cell nuclear transfer has successfully been used to clone several mammalian species including the mouse, albeit with extremely low efficiency. This study investigated gene expression in cloned mouse embryos derived from cumulus cell donor nuclei, in comparison with in vivo fertilized mouse embryos, at progressive developmental stages. Enucleation was carried out by the conventional puncture method rather than by the piezo-actuated technique, whereas nuclear transfer was achieved by direct cumulus nuclear injection. Embryonic development was monitored from chemically induced activation on day 0 until the blastocyst stage on day 4. Poor developmental competence of cloned embryos was observed, which was confirmed by lower cell counts in cloned blastocysts, compared with the in vivo fertilized controls. Subsequently, real-time polymerase chain reaction was used to analyze and compare embryonic gene expression at the 2-cell, 4-cell, and blastocyst stages, between the experimental and control groups. The results showed reduced expression of the candidate genes in cloned 2-cell stage embryos, as manifested by poor developmental competence, compared with expression in the in vivo fertilized controls. Cloned 4-cell embryos and blastocysts, which had overcome the developmental block at the 2-cell stage, also showed up-regulated and down-regulated expression of several genes, strongly suggesting incomplete nuclear reprogramming. We have therefore demonstrated that aberrant embryonic gene expression is associated with low developmental competence of cloned mouse embryos. To improve the efficiency of somatic cell nuclear transfer, strategies to rectify aberrant gene expression in cloned embryos should be investigated.

“…Interestingly, Nagao et al (1998) reported, decreasing physical performance in congenic mice with mismatch between the nuclear and the mitochondrial genome. When foreign mitochondrial are introduced in conducting interspecies NT procedures, it is possible that mitochondrial heteroplasmy, as well as chromosome number, may be key factors that affect embryonic development and in utero survivability of interspecies NT embryos (Sansinena et al, 2005).…”

This study was conducted to increase the efficiency of canine embryo production by intergeneric somatic cell nuclear transfer (SCNT) technology. The effect of oocyte recipient for development of intergeneric canine somatic cell cloning embryos were examined. Bovine and porcine cumulus oocyte complexes (COCs) were collected from slaughterhouse ovaries and matured in TCM-199 medium depend on species. Adult dog fibroblasts collected from 3.5 years old Afghanhound dog, and cell between passage 1 and passage 10 used for intergeneric somatic cell cloning using bovine and porcine oocytes as oocyte cytoplasm donor. The result showed that oocytes from bovine and porcine can de-differentiated canine nucleus and no different between bovine and porcine oocyte in fusion and embryo development in vitro. Canine intergeneric cloned embryos developed to morula stages in vitro.

“…Currently, bovine oocytes have been used as recipient cytoplasts in several interspecies and intergeneric cloning studies, such as in the gaur [12], buffalo [13], banteng [15], dog [37] and human [19], and they have been successful in supporting blastocyst formation. Alternatively, not every species has been able to develop to the blastocyst stage when reconstructed with bovine oocytes; it has been reported that cloned mouse [38], equine [39] and domestic cat [22] embryos derived from fibroblasts arrested their development at the eight-cell stage, which is similar to this study.…”

“…Although the remaining population of the MC is not known, the International Union for the Conservation of Nature and Natural Resources (IUCN) classifies the MC as intermediate and the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) has listed the MC as endangered in Appendix I. Since endangered species have a limited supply of recipient oocytes, the oocyte cytoplasm of domestic species, such as the bovine, sheep, rabbit, DC and dog, has been used for dedifferentiation of the somatic cell nucleus from the rat, pig, monkey, sheep [11], gaur [12], buffalo [13], giant panda [14], banteng [15], wolf [16], goat [17] monkey [18], human [19,20] and several felid species [6][7][8][9][10]21]. Gomez et al [10] suggested that DC oocytes can be used for wildcat preservation by interspecies or intergeneric NT techniques.…”

Abstract. The aim of this study was to investigate if reconstructed felid embryos obtained by intraspecies or intergeneric cloning can develop in vitro. Fibroblast cells (f) from a domestic cat (DCf), marbled cat (MCf) and bovine (Bf) were used as donor cells, and oocytes (o) from domestic cats (DCo) and bovine (Bo) were used as recipient cytoplasts. There were two intraspecies (donor cell + recipient cytoplast: DCf + DCo and Bf + Bo) and three intergeneric (MCf + DCo, DCf + Bo and MCf + Bo) cloning groups in the study. In Experiment 1, the effects of manipulation media, modified or Emcare holding medium (EHM), on in vitro development of DCf + DCo embryos were investigated. The blastocyst formation rate (BFR) of the embryos manipulated in EHM (33.3%) was higher (P<0.05) compared with those manipulated in 199H (18.1%). In Experiment 2, DCf + DCo and MCf + DCo embryos were cocultured with or without domestic cat oviductal epithelium cells. Irrespective of coculture, the same BFR was obtained for DCf + DCo embryos (44.4 vs. 38.0%), while MCf + DCo embryos could not develop beyond the morula stage. In experiment 3, although the development of MCf + DCo and DCf + Bo embryos was arrested at the morula stage, 8.6% of MCf + Bo embryos were able to develop to the blastocyst stage. These results demonstrated that EHM was superior to 199H as an embryo manipulation medium and that the DCo and Bo could support the early embryonic development of intergeneric cloned marbled cat embryos up to the morula stage. However, postimplantation development still needs to be investigated. Key words: Bovine cytoplast, Development, Felid embryos, Intergeneric cloning, Marbled cat (J. Reprod. Dev. 57: [385][386][387][388][389][390][391][392] 2011) is the world's first domestic cat (DC) cloned using an adult somatic cell as a donor nucleus [1]. To date, several reports have successfully documented domestic kittens [2][3][4][5] cloned by NT. There are many efforts currently underway to study the conservation of endangered felid species. In order to preserve and increase the numbers of endangered felid species such as the African wildcat [6,7], leopard cat [3, 8], marbled cat (MC; Pardofelis marmorata) [9] and sand cat [10], nuclear transfer (NT) has been used to produce cloned embryos.Interspecies or intergeneric NT is a high potential technique for conserving a number of endangered species. One such species is the MC, a wildcat that is considered at risk of extinction in Southeast Asia. The size of the MC is larger than a big DC, and it has a base fur color that ranges from brownish to grey with a pattern of irregular dark marbled blotches and spots outlined with black strips. The declining population could be attributed to poaching and human destruction of the natural ecosystem. Although the remaining population of the MC is not known, the International Union for the Conservation of Nature and Natural Resources (IUCN) classifies the MC as intermediate and the Convention on International Trade in Endangered Species of Wild Fauna and Flo...
