Biol Proced Online 2024; 26:3. [PMID: 38279106 PMCID: PMC10811837 DOI: 10.1186/s12575-024-00230-9] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/15/2023] [Accepted: 01/16/2024] [Indexed: 01/28/2024] Open
Abstract
BACKGROUND Generating targeted mutant mice is a crucial technology in biomedical research. This study focuses on optimizing the CRISPR/Cas9 system uptake into sperm cells using the methyl β-cyclodextrin-sperm-mediated gene transfer (MBCD-SMGT) technique to generate targeted mutant blastocysts and mice efficiently. Additionally, the present study elucidates the roles of cholesterol and reactive oxygen species (ROS) in the exogenous DNA uptake by sperm. RESULTS In this study, B6D2F1 mouse sperm were incubated in the c-TYH medium with different concentrations of MBCD (0, 0.75, 1, and 2 mM) in the presence of 20 ng/µl pCAG-eCas9-GFP-U6-gRNA (pgRNA-Cas9) for 30 min. Functional parameters, extracellular ROS, and the copy numbers of internalized plasmid per sperm cell were evaluated. Subsequently, in vitro fertilization (IVF) was performed and fertilization rate, early embryonic development, and transfection rate were assessed. Finally, our study investigated the potential of the MBCD-SMGT technique in combination with the CRISPR-Cas9 system, referred to as MBCD-SMGE (MBCD-sperm-mediated gene editing), for generating targeted mutant blastocysts and mice. Results indicated that cholesterol removal from the sperm membrane using MBCD resulted in a premature acrosomal reaction, an increase in extracellular ROS levels, and a dose-dependent influence on the copy numbers of the internalized plasmids per sperm cell. Moreover, the MBCD-SMGT technique led to a larger population of transfected motile sperm and a higher production rate of GFP-positive blastocysts. Additionally, the current study validated the targeted indel in blastocyst and mouse derived from MBCD-SMGE technique. CONCLUSION Overall, this study highlights the significant potential of the MBCD-SMGE technique for generating targeted mutant mice. It holds enormous promise for modeling human diseases and improving desirable traits in animals.

Abstract
Estradiol is a steroid hormone excreted from the female gonads, mainly during the pre-estrus. However, the potential effects of estradiol are yet to be explored on sperm parameters through cryopreservation. In this study, we supplemented estradiol, 3 and 5 μM, in the goat semen extender and assessed the sperm parameters after a freeze-thawing process. Sperm motility was assessed using the computer-assisted sperm analysis system. Sperm viability and membrane integrity improved using both 3 and 5 μM concentrations of estradiol. The highest rate of progressive motility was observed in the 3 μM estradiol group. However, a higher concentration of estradiol (5 μM) reduced the progressive motility. Then, we were interested to see if the supportive effect of estradiol on sperm motility is mediated through the intracellular concentration of calcium ionophore. We supplemented the semen extender with 1 and 10 mM ethylenediaminetetraacetic acid (EDTA) and showed that 1 mM has no adverse effect on progressive sperm motility. Then, estradiol (3 μM) was supplemented with or without EDTA (1 mM) into the semen extender. Individual EDTA treatment improved the progressive sperm motility compared to the control group. However, in the presence of estradiol, EDTA treatment reduced the progressive motility compared to the individual estradiol group. This indicated a considerable interaction between estradiol and EDTA for progressive sperm motility. Indeed, EDTA reduced the supportive effects of estradiol on sperm cryopreservation parameters. These results indicated that induction of higher progressive sperm motility in response to estradiol is a calcium-dependent process, as the EDTA did completely abrogate the estradiol-mediated effect.

Abstract
Introduction: In this review, the analysis of technologies for obtaining biologically active proteins from various sources is carried out, and the comparative analysis of technologies for creating producers of biologically active proteins is presented. Special attention is paid to genetically modified animals as bioreactors for the pharmaceutical industry of a new type. The necessity of improving the technology of development transgenic rabbit producers and creating a platform solution for the production of biological products is substantiated.
The advantages of using TrB for the production of recombinant proteins: The main advantages of using TrB are the low cost of obtaining valuable complex therapeutic human proteins in readily accessible fluids, their greater safety relative to proteins isolated directly from human blood, and the greater safety of the activity of the native protein.
The advantages of the mammary gland as a system for the expression of recombinant proteins: The mammary gland is the organ of choice for the expression of valuable recombinant proteins because milk is easy to collect in large volumes.
Methods for obtaining transgenic animals: The modern understanding of the regulation of gene expression and the discovery of new tools for gene editing can increase the efficiency of creating bioreactors for animals and help to obtain high concentrations of the target protein.
The advantages of using rabbits as bioreactors producing recombinant proteins in milk: The rabbit is a relatively small animal with a short duration of gestation, puberty and optimal size, capable of producing up to 5 liters of milk per year per female, receiving up to 300 grams of the target protein.

Efficiency and cell viability implications using tip type electroporation in zebrafish sperm cells. Mol Biol Rep 2020; 47:5879-5887.

Abstract
Sperm-mediated gene transfer (SMGT) has a potential use for zebrafish transgenesis. However, transfection into fish sperm cells still needs to be improved. The objective was to demonstrate the feasibility of tip type electroporation in zebrafish sperm, showing a protocol that provide high transfection efficiency, with minimal side-effects. Sperm was transfected with a Cy3-labelled DNA using tip type electroporation with voltages ranging from 500 to 1500 V. Sperm kinetics parameters were assessed using Computer Assisted Semen Analysis (CASA) and cell integrity, reactive oxygen species (ROS), mitochondrial functionality and transfection rate were evaluated by flow cytometry. The transfection rates were positively affected by tip type electroporation, reaching 64.9% ± 3.6 in the lowest voltage used (500 V) and 86.6% ± 1.9 in the highest (1500 V). The percentage of overall motile sperm in the electrotransfected samples was found to decrease with increasing field strength (P < 0.05). Increase in the sperm damaged plasma membrane was observed with increasing field strength (P < 0.05). ROS and sperm mitochondrial functionality did not present a negative response after the electroporation (P > 0.05). Overall results indicate that tip type electroporation enhances the internalization of exogenous DNA into zebrafish sperm cells with minimal harmful effects to sperm cells.

Robust DNase activity of the ooplasm can act as a gametic transfection barrier in rainbow trout. Theriogenology 2020; 142:62-66.

Abstract
In this study, we evaluated DNase activity of rainbow trout oocyte using an in vitro and in vivo study. First, synthetic single strand and natural double strand DNA from Eukaryotic and prokaryotic sources as well as naked DNA were in vitro incubated with the oocyte cytoplasm. Results showed that the DNase activity of rainbow trout oocyte is strong enough to degrade any type of DNA at the onset of the incubation. Then, we evaluated if similar to the mammalian species, dead spermatozoa from rainbow trout can protect exogenous DNA from oocyte DNases. A series of dead spermatozoa was incubated with pDB2, carrying EGFP transgene, for 30 min followed by the ooplasm treatment for an additional 30 min. Not only did oocyte DNases completely degrade the exogenous DNA, but also it degraded the compact genome of spermatozoa. In conclusion, in vitro results clearly showed that strong DNase activity of ooplasm could degrade any types of foreign DNAs including oligonucleotides and intensively compact sperm genome. The strong DNase activity of rainbow trout ooplasm could be a stumbling block for genetic modification using plasmids in salmonids.

Abstract
Episomal plasmids based on a scaffold/matrix attachment region (S/MAR) are extrachromosomal DNA entities that replicate once per cell cycle and are stably maintained in cells or tissue. We generated minicircles, episomal plasmids devoid of bacterial sequences, and show that they are stably transmitted in clonal primary bovine fibroblasts without selection pressure over more than two months. Total DNA, plasmid extraction and fluorescence in situ hybridization (FISH) analyses suggest that the minicircles remained episomal and were not integrated into the genome. Minicircles survived extended periods in serum-starved cells, which indicates that ongoing transcription in non-proliferating cells is not necessary for the maintenance of S/MAR-episomes. To test whether minicircles endure the process of somatic cell nuclear transfer (SCNT), we used cell-cycle synchronized, serum-starved, minicircle-containing cells. Analysis of cells outgrown from SCNT-derived blastocysts shows that the minicircles are maintained through SCNT and early embryonic development, which raises the prospect of using cell lines with episomal minicircles for the generation of transgenic animals.

Abstract
Abstract. Sperm-mediated gene transfer (SMGT) has been considered as an innovative
device for transgenesis on a mass scale by taking advantage of live
spermatozoa to transfer exogenous DNA. However, the fertilizing ability of
transfected sperm cells and the poor reproducibility of this method are still
matters of controversy. Hence, the current study was conducted to evaluate
transfecting the enhanced green fluorescent protein (EGFP) as the source of
exogenous DNA into bovine spermatozoa using a high-performance polymer
reagent as well as assessing the fertilizing capacity of transfected sperm
cells by in vitro fertilization (IVF). In the first experiment, three
different concentrations of rhodamine-labeled DNA and high-performance
polymer transfection reagent, X-tremeGENE HP, were used to transfect bovine
spermatozoa. In the second experiment, IVF and fluorescence microscopy
methods were utilized to assess the fertilizing capacity of sperm cells
carrying exogenous DNA when X-tremeGENE HP was used either alone or with
dimethyl sulfoxide (DMSO) treatment. Findings revealed that at 1 µL
X-tremeGENE HP and 1 µg of DNA concentration, approximately
one-third of total spermatozoa were transfected. However, following IVF and
fluorescence microscopy, no EGFP expression was detected in zygotes and
morula-stage embryos. Results of this study showed that, although X-tremeGENE
HP could transfer EGFP to bovine spermatozoa, transfected sperm cells were
unable to transfer foreign DNA to matured bovine oocytes. Under our
experimental conditions, we hypothesized that the absence of the EGFP
fluorescence signal in embryos could be due to the detrimental effects of
transfection treatments on sperm cells' fertility performance as well as
incompetency of IVF to produce transgenic embryos using transfected sperm
cells.

Abstract
The ICSI-sperm mediated gene transfer (ICSI-SMGT) has been used to produce transgenic mice with high efficiency; however, the efficiency of this technique in farm animals is still less than desirable. Pretreatment of sperm with membrane destabilizing agents can improve the efficiency of ICSI in cattle. The objective of the present study was to evaluate streptolysin-O (SLO) as a novel treatment to permeabilize the bovine sperm membrane and assess its effect on efficiency of generating transgenic embryos by ICSI-SMGT. First, there was evaluation of the plasma membrane integrity (SYBR/PI), acrosome membrane integrity (PNA/FITC), DNA damage (TUNEL) and binding capacity of exogenous DNA (Nick Translation) in bull sperm treated with SLO. Subsequently, there was assessment of embryonic development and the efficiency in generating transgenic embryos with enhanced expression of the gene for green fluorescent protein (EGFP). Results indicate that SLO efficiently permeabilizes the plasma and acrosome membranes of bull spermatozoa and increases binding of exogenous DNA mostly to the post-acrosomal region and tail without greatly affecting the integrity of the DNA. Furthermore, treatment of bull spermatozoa with SLO prior to the injection of oocytes by ICSI-SMGT significantly increased the rate of embryo expression of the EGFP gene. Future experiments are still needed to determine the effect of this treatment on the development and transgene expression in fetuses and animals produced by ICSI-SMGT.

Abstract
Sperm-mediated gene transfer (SMGT) is a simple, fast, and economical biotechnological tool for producing transgenic animals. However, transgene expression with this technique in bovine embryos is still inefficient due to low uptake and binding of exogenous DNA in spermatozoa. The present study evaluated the effects of sperm membrane destabilization on the binding capacity, location and quantity of bound exogenous DNA in cryopreserved bovine spermatozoa using Triton X-100 (TX-100), lysolecithin (LL) and sodium hydroxide (NaOH). Effects of these treatments were also evaluated by intracytoplasmic sperm injection (ICSI)-SMGT. Results showed that all treatments bound exogenous DNA to spermatozoa including the control. Spermatozoa treated with different membrane destabilizing agents bound the exogenous DNA throughout the head and tail of spermatozoa, compared with the control, in which binding occurred mainly in the post-acrosomal region and tail. The amount of exogenous DNA bound to spermatozoa was much higher for the different sperm treatments than the control (P < 0.05), most likely due to the damage induced by these treatments to the plasma and acrosomal membranes. Exogenous gene expression in embryos was also improved by these treatments. These results demonstrated that sperm membrane destabilization could be a novel strategy in bovine SMGT protocols for the generation of transgenic embryos by ICSI.

Abstract
Sperm-mediated gene transfer (SMGT) is based on the capacity of sperm to bind exogenous DNA and transfer it into the oocyte during fertilization. In bovines, the progress of this technology has been slow due to the poor reproducibility and efficiency of the production of transgenic embryos. The aim of the present study was to evaluate the effects of different sperm transfection systems on the quality and functional parameters of sperm. Additionally, the ability of sperm to bind and incorporate exogenous DNA was assessed. These analyses were carried out by flow cytometry and confocal fluorescence microscopy, and motility parameters were also evaluated by computer-assisted sperm analysis (CASA). Transfection was carried out using complexes of plasmid DNA with Lipofectamine, SuperFect and TurboFect for 0.5, 1, 2 or 4 h. The results showed that all of the transfection treatments promoted sperm binding and incorporation of exogenous DNA, similar to sperm incorporation of DNA alone, without affecting the viability. Nevertheless, the treatments and incubation times significantly affected the motility parameters, although no effect on the integrity of DNA or the levels of reactive oxygen species (ROS) was observed. Additionally, we observed that transfection using SuperFect and TurboFect negatively affected the acrosome integrity, and TurboFect affected the mitochondrial membrane potential of sperm. In conclusion, we demonstrated binding and incorporation of exogenous DNA by sperm after transfection and confirmed the capacity of sperm to spontaneously incorporate exogenous DNA. These findings will allow the establishment of the most appropriate method [intracytoplasmic sperm injection (ICSI) or in vitro fertilization (IVF)] of generating transgenic embryos via SMGT based on the fertilization capacity of transfected sperm.

Abstract
The use of recombinant proteins has increased in diverse commercial sectors. Various systems for protein production have been used for the optimization of production and functional protein expression. The mammary gland is considered to be a very interesting system for the production of recombinant proteins due to its high level of expression and its ability to perform post-translational modifications. Cows produce large quantities of milk over a long period of lactation, and therefore this species is an important candidate for recombinant protein expression in milk. However, transgenic cows are more difficult to generate due to the inefficiency of transgenic methodologies, the long periods for transgene detection, recombinant protein expression and the fact that only a single calf is obtained at the end of each pregnancy. An increase in efficiency for transgenic methodologies for cattle is a big challenge to overcome. Promising methodologies have been proposed that can help to overcome this obstacle, enabling the use of transgenic cattle as bioreactors for protein production in milk for industry.

Abstract
DNA uptake in the post-acrosomal region of the spermatozoa takes place exclusively in immotile spermatozoa that are naturally unable to fertilize eggs. The present study aimed to assess whether passive transmission of non-viral vectors to the surrounding areas of chicken embryos could be an alternate mechanism in chicken sperm-mediated gene transfer. First, the presence of nucleases in rooster seminal plasma was evaluated. Semen ejaculates from five roosters were centrifuged and the supernatant was incubated with pBL2 for 1 h. A robust nuclease cocktail was detected in the rooster semen. To overcome these nucleases, plasmid-TransIT combinations were incubated with semen for 1 h. Incubation of exogenous DNA in the lipoplex structure could considerably bypass the semen nuclease effect. Then, intravaginal insemination of 1 × 10(9) sperm mixed with lipoplexes (40 µg pBL2:40 µl TransIT) was carried out in 15 virgin hens. Neither the epithelial tissue from the inseminated female reproductive tracts nor the produced embryos following artificial insemination showed the transgene. To remove any bias in the transgene transmission possibility, the plasmid-TransIT admixture was directly injected in close vicinity of the embryos in newly laid eggs. Nonetheless, none of the produced fetuses or chicks carried the transgene. In conclusion, the results of the present study revealed a nuclease admixture in rooster seminal plasma, and passive/active transmission of the non-viral vector into close vicinity of the chicken embryo was inefficient for producing transgenic chicks.

Abstract
Biomedical nanotechnology allows us to engineer versatile nanosized platforms that are comparable in size to biological molecules and intracellular organelles. These platforms can be loaded with large amounts of biological cargo, administered systemically and act at a distance, target specific cell populations, undergo intracellular internalization via endogenous uptake mechanisms, and act as contrast agents or release cargo for therapeutic purposes. Over recent years, nanomaterials have been increasingly viewed as favorable candidates for intragamete delivery. Particularly in the case of sperm, nanomaterial-based approaches have been shown to improve the efficacy of existing techniques such as sperm-mediated gene transfer, loading sperm with exogenous proteins, and tagging sperm for subsequent sex- or function-based sorting. In this short review, we provide an outline of the current state of nanotechnology for biomedical applications in reproductive biology and present highlights from a series of our studies evaluating the use of specialized silica nanoparticles in boar sperm as a potential delivery vehicle into mammalian gametes. The encouraging data obtained already from the porcine model in our laboratory have formed the basis for ethical approval of similar experiments in human sperm, thereby bringing us a step closer toward the potential use of this novel technology in the clinical environment.

Abstract
Aim: This study aimed to investigate the effects of actively targeting mesoporous silica nanoparticles (MSNPs) toward mammalian sperm with a cell-penetrating peptide (C105Y), with subsequent analysis of binding rates and nano-safety profiles. Materials & methods: Boar sperm were exposed in vitro to C105Y-functionalized MSNPs or free C105Y, in a series of increasing doses for up to 2 h, followed by the evaluation of sperm motility, kinematic parameters, acrosome morphology, MSNP-sperm binding and cell fluorescence levels. Results: C105Y-functionalized MSNPs preserved their biocompatibility with sperm, and exhibited an approximately fourfold increase in affinity toward gametes, compared with unmodified MSNPs, during the early stages of incubation. Conclusion: Our findings support the application of MSNPs and active targeting to sperm as valuable tools for reproductive biology.

Ovum pick up, intracytoplasmic sperm injection and somatic cell nuclear transfer in cattle, buffalo and horses: from the research laboratory to clinical practice. Theriogenology 2014; 81:138-51.

Abstract
Assisted reproductive techniques developed for cattle in the last 25 years, like ovum pick up (OPU), intracytoplasmic sperm injection (ICSI), and somatic cell nuclear transfer, have been transferred and adapted to buffalo and horses. The successful clinical applications of these techniques require both the clinical skills specific to each animal species and an experienced laboratory team to support the in vitro phase of the work. In cattle, OPU can be considered a consolidated technology that is rapidly outpacing conventional superovulation for embryo transfer. In buffalo, OPU represents the only possibility for embryo production to advance the implementation of embryo-based biotechnologies in that industry, although it is still mainly in the developmental phase. In the horse, OPU is now an established procedure for breeding from infertile and sporting mares throughout the year. It requires ICSI that in the horse, contrary to what happens in cattle and buffalo, is very efficient and the only option because conventional IVF does not work. Somatic cell nuclear transfer is destined to fill a very small niche for generating animals of extremely high commercial value. The efficiency is low, but because normal animals can be generated it is likely that advancing our knowledge in that field might improve the technology and reduce its cost.
