Abstract
Modeling a human disease is an essential part of biomedical research. The recent advances in the field of molecular genetics made it possible to obtain genetically modified animals for the study of various diseases. Not only monogenic disorders but also chromosomal and multifactorial disorders can be mimicked in lab animals due to genetic modification. Even human infectious diseases can be studied in genetically modified animals. An animal model of a disease enables the tracking of its pathogenesis and, more importantly, to test new therapies. In the first part of this paper, we review the most common DNA modification technologies and provide key ideas on specific technology choices according to the task at hand. In the second part, we focus on the application of genetically modified mice in studying human diseases.

Meinecke B, Meinecke-Tillmann S. Lab partners: oocytes, embryos and company. A personal view on aspects of oocyte maturation and the development of monozygotic twins. Anim Reprod 2023; 20:e20230049. [PMID: 37547564 PMCID: PMC10399133 DOI: 10.1590/1984-3143-ar2023-0049] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/31/2023] [Accepted: 06/12/2023] [Indexed: 08/08/2023] Open
Abstract
The present review addresses the oocyte and the preimplantation embryo, and is intended to highlight the underlying principle of the "nature versus/and nurture" question. Given the diversity in mammalian oocyte maturation, this review will not be comprehensive but instead will focus on the porcine oocyte. Historically, oogenesis was seen as the development of a passive cell nursed and determined by its somatic compartment. Currently, the advanced analysis of the cross-talk between the maternal environment and the oocyte shows a more balanced relationship: Granulosa cells nurse the oocyte, whereas the latter secretes diffusible factors that regulate proliferation and differentiation of the granulosa cells. Signal molecules of the granulosa cells either prevent the precocious initiation of meiotic maturation or enable oocyte maturation following hormonal stimulation. A similar question emerges in research on monozygotic twins or multiples: In Greek and medieval times, twins were not seen as the result of the common course of nature but were classified as faults. This seems still valid today for the rare and until now mainly unknown genesis of facultative monozygotic twins in mammals. Monozygotic twins are unique subjects for studies of the conceptus-maternal dialogue, the intra-pair similarity and dissimilarity, and the elucidation of the interplay between nature and nurture. In the course of in vivo collections of preimplantation sheep embryos and experiments on embryo splitting and other microsurgical interventions we recorded observations on double blastocysts within a single zona pellucida, double inner cell masses in zona-enclosed blastocysts and double germinal discs in elongating embryos. On the basis of these observations we add some pieces to the puzzle of the post-zygotic genesis of monozygotic twins and on maternal influences on the developing conceptus.

AAV infection of bovine embryos: Novel, simple and effective tool for genome editing. Theriogenology 2022; 193:77-86.

Abstract
Adeno-associated viruses (AAV) are widely used in the field of genetically modified organism production. In this work, transduction of bovine embryos by AAV was selected as a potential approach to perform genetic modifications: we have used recombinant AAV to produce GFP-positive bovine embryos. Five different AAV serotypes were used to evaluate their ability to deliver genetic material into the bovine embryos. AAV9 serotype demonstrated minimal effectiveness (38,10%) as the genetic material transfer tool. Four other serotypes of AAVs (AAV1, AAV2, AAV6 and AAV-DJ) showed very close transduction efficiency (52,94-58,33%). CD209 is a C-type lectin receptor which is presented on the surface of macrophages and dendritic cells. CD209 recognizes a broad range of pathogens in a rather nonspecific manner. Production of CD209 knock-out is relevant for better understanding of infection mechanisms. Potentially, production of such knock-out may enable animals to become resistant to various infections. We have analyzed DNA samples from 22 blastocysts obtained after in vitro culture of zygotes subjected to recombinant AAV action. We have detected that 3 of 22 analyzed blastocysts contained mosaic CD209 frameshifts. Therefore, we have demonstrated proof of principle that application of AAV as a genome editing tool is an effective method for obtaining genetically modified cattle embryos.

Abstract
Objective Production of genetically modified mice including Knock-out (KO) or Knock-in (KI) mice is necessary for organism-level phenotype analysis. Embryonic stem cell (ESC)-based technologies can produce many genetically modified mice with less time without crossing. However, a complicated manual operation is required to increase the number of ESC colonies. Here, the objective of this study was to design and demonstrate a new device to easily find colonies and carry them to microwells. Results We developed a polydimethylsiloxane-based device for easy manipulation and isolation of ESC colonies. By introducing ESC colonies into the groove placed near culturing microwells, users can easily find, pick up and carry ESC colonies to microwells. By hydrophilic treatment using bovine serum albumin, 2-μL droplets including colonies reached the microwell bottom. Operation time using this device was shortened for both beginners (2.3-fold) and experts (1.5-fold) compared to the conventional colony picking operation. Isolated ESC colonies were confirmed to have maintained pluripotency. This device is expected to promote research by shortening the isolation procedure for ESC colonies or other large cells (e.g. eggs or embryos) and shortening training time for beginners as a simple sorter.

Abstract
Production of chimeric animals is often a necessity for the generation of genetically
modified animals and has gained popularity in recent years in regenerative medicine for
the reconstruction of xenogeneic organs. Aggregation and injection methods are generally
used to produce chimeric mice. In the aggregation method, the chimeras are produced by
co-culturing embryos and stem cells, and keeping them physically adhered, although it may
not be an assured method for producing chimeric embryos. In the injection method, the
chimeras are produced by injecting stem cells into the zona pellucida using
microcapillaries; however, this technique requires a high degree of skill. This study
aimed to establish a novel method for producing chimeric embryos via water-in-oil droplets
that differs from conventional methods. In this study, embryonic stem cells and embryos
were successfully isolated in the droplets, and the emergence of chimeric embryos was
confirmed by co-culture for 6 h. Using this method, the control and operability of stem
cell numbers could be regulated, and reproducibility and quantification were improved
during the production of chimeric embryos. In addition to the conventional methods for
producing chimeric embryos, the novel method described here could be employed for the
efficient production of chimeric animals.

Abstract
Systems-biological approaches, such as comprehensive identification and analysis of system components and networks, are necessary to understand design principles of human physiology and pathology. Although reverse genetics using mouse models have been used previously, it is a low throughput method because of the need for repetitive crossing to produce mice having all cells of the body with knock-out or knock-in mutations. Moreover, there are often issues from the interspecific gap between humans and mice. To overcome these problems, high-throughput methods for producing knock-out or knock-in mice are necessary. In this review, we describe 'next-generation' human genetics, which can be defined as high-throughput mammalian genetics without crossing to knock out human-mouse ortholog genes or to knock in genetically humanized mutations.
