Abstract
This study was designed to undertake a risk assessment to identify the health status of rats fed with somatic cell nuclear transfer (SCNT)-cloned Korean native beef cattle (Hanwoo) meat for 26 weeks. The rats were randomly divided into 5 groups, each consisting of 12 male (142.6 ± 5.23 g) and 12 female (113.7 ± 6.31 g) rats each. The animals were fed commercial pellets (control), pellets containing 5% (N-5) and 10% (N-10) of normal cattle meat, and diets containing 5% (C-5) and 10% (C-10) of cloned cattle meat. The mortality; clinical signs; body weight; food consumption; urinary, hematology, blood biochemistry, and histopathological analyses; and absolute and relative organ weights were analyzed and compared. During the 26-week test period, health status–related factors of the rats fed on cloned Hanwoo meat were found to have no test substance–related toxicities. The only difference was the increased uterus weight in female C-10 rats as compared to their counterparts counterparts ( p < .05). On the basis of these health status results, it can be postulated that no food consumption risks might arise from the long-term feeding of cloned cattle meat in rats.

In vitro and in vivo genotoxic effects of somatic cell nuclear transfer cloned cattle meat. Food Chem Toxicol 2011; 49:2273-8.

Abstract
Although the nutritional composition and health status after consumption of the meat and milk derived from both conventionally bred (normal) and somatic cell nuclear transferred (cloned) animals and their progeny are not different, little is known about their food safeties like genetic toxicity. This study is performed to examine both in vitro (bacterial mutation and chromosome aberration) and in vivo (micronucleus) genotoxicity studies of cloned cattle meat. The concentrations of both normal and cloned cattle meat extracts (0-10×) were tested to five strains of bacteria (Salmonella typhimurium: TA98, TA100, TA1535, and TA1537; Escherichia coli: WP2uvrA) for bacterial mutation and to Chinese hamster lung (CHL/IU) cells for chromosome aberration, respectively. For micronucleus test, ICR mice were divided into five dietary groups: commercial pellets (control), pellets containing 5% (N-5) and 10% (N-10) normal cattle meat, and pellets containing 5% (C-5) and 10% (C-10) cloned cattle meat. No test substance-related genotoxicity was noted in the five bacterial strains, CHL/IU cells, or mouse bone marrow cells, suggesting that the cloned cattle meat potentially may be safe in terms of mutagenic hazards. Thus, it can be postulated that the cloned cattle meat do not induce any harmful genotoxic effects in vitro and in vivo.

Abstract
If the full potential of chromatin transfer (CT) technology is to be realized for both animal production and biomedical applications it is imperative that the efficiency of the reprogramming process be improved, and the potential for deleterious development be eliminated. Generation of the first cloned animals from adult somatic cells demonstrated that development is substantially an epigenetic process (Wilmut I, Schnieke AE, McWhir J, Kind AJ, Campbell KH, 1997. Viable offspring derived from fetal and adult mammalian cells. Nature. 385(6619): 810-813.). In this study, we provide preliminary evidence that the epigenetic state of the donor cell, may be valuable in assessing potential cloning success. We have measured key indicators of cellular epigenetic state in both serially derived cell populations of the same genetic origin, but differing in epigenomic status, and in a distinct cohort of donor cell populations with diverse genetic origins and epigenomic status. Specifically, the relative abundance of particular histone modifications in donor populations prior to manipulation has been correlated with the measurable variance in reprogramming efficiencies observed following CT, as defined by the number of resulting live births and healthy progeny, and the concomitant incidence of deleterious growth measures (notably the appearance of large offspring syndrome (LOS)). Thus, we suggest that the likely outcome and relative success of cloning may be predictable based on the expression of discriminating histone marks present in the donor cell population before CT. This approach may provide the basis of a prognostic signature for the future evaluation and risk assessment of putative donor cells prior to CT, and thus increase future cloning success and alleviate the incidence of abnormal development.

Abstract
It has become evident that advances in farm animal reproduction have become increasingly dependent on fundamental scientific research in addition to an understanding of the physiological processes involved in reproduction. As a consequence, most innovations are now coming from a long linear process starting with fundamental scientific research to their application on the farm and lastly, consumer acceptance. The emerging perception of life's complexity is also indicating that technical advances must be better understood before they are implemented by the producer and accepted by the public. To the biological complexity, one must now add the complexity of human interaction on a global level through regulation, international trade and public information. In this context, more than ever, advancements in animal reproduction must be developed in parallel with the scientific understanding of the cause and consequences of human intervention.
