[PMID: 33636584 DOI: 10.1016/j.repbio.2021.100486] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/14/2020] [Revised: 02/03/2021] [Accepted: 02/07/2021] [Indexed: 11/26/2022]
Abstract
This study compared the quality parameters of bull semen sexed using an immunological method with those of conventional semen by imaging flow cytometry and applied this semen in dairy farm trials. Semen samples were collected from ten ejaculates from five bulls. Each sample was divided into two treatments: conventional semen (CON) and semen sexed using monoclonal male-specific antibodies combined with the complement system for cytotoxicity reaction (IC-sexed). After obtaining frozen-thawed semen, we used imaging flow cytometry to assess acrosome integrity, sperm sex ratio and viability. Sperm morphology was evaluated using eosin-nigrosin staining. The percentage acrosome integrity did not differ between IC-sexed and CON semen (P = 0.313). The sperm sex ratio showed that the percentage of live X-chromosome-bearing sperm was higher than that of live Y-chromosome-bearing sperm in IC-sexed semen (P = 0.001). IC-sexed semen showed a higher percentage of head and tail defects than did CON semen (P = 0.019). In field trials, 585 cows were subjected randomly to AI with CON or IC-sexed semen. The pregnancy rate of the IC-sexed group did not differ from that of the CON group (P = 0.535). However, IC-sexed semen produced a significantly higher percentage of female calves than did CON semen (P = 0.031). Thus, immunological sexing did not adversely affect the acrosome integrity of sperm. Furthermore, a female calf birth rate of over 74 % can potentially be achieved using IC-sexed semen. These findings could help farmers to replace heifers in their herds.

Abstract
The use of serologically detectable male (SDM; also called H-Y) antigens to identify male
embryos may be limited by the source of anti-SDM antibody. In the present study, novel
anti-SDM B9-Fab recombinant clones (obtained by chain shuffling of an A8 original clone)
were used to detect SDM antigens on murine embryos. Murine morulae and blastocysts (n=138)
were flushed from the oviducts of Kunming mice and incubated with anti-SDM B9-Fab for 30
min at 37°C. With an indirect immunofluorescence assay, the membrane and inner cell mass
had bright green fluorescence (presumptive males). Overall, 43.5% (60/138) were classified
as presumptive males and 56.5% (78/138) as presumptive females, with 85.0 and 88.5% of
these, respectively, confirmed as correct predictions (based on PCR analysis of a
male-specific [Sry] sequence). We concluded that the anti-SDM B9-Fab molecule had
potential for non-invasive, technically simple immunological sexing of mammalian
embryos.

Abstract
The fetal semi-allograft can induce expansion and tolerance of antigen-specific maternal T and B cells through paternally inherited major histocompatibility complex and minor histocompatibility antigens (mHAgs). The effects of these antigens have important consequences on the maternal immune system both during and long after pregnancy. Herein, we investigate the possibility that the placental syncytiotrophoblast and deported trophoblastic debris serve as sources of fetal mHAgs. We mapped the expression of four mHAgs (human mHAg 1, pumilio domain-containing protein KIAA0020, B-cell lymphoma 2-related protein A1, and ribosomal protein S4, Y linked) in the placenta. Each of these proteins was expressed in several placental cell types, including the syncytiotrophoblast. These antigens and two additional Y chromosome-encoded antigens [DEAD box polypeptide 3, Y linked (DDX3Y), and lysine demethylase5D] were also identified by RT-PCR in the placenta, purified trophoblast cells, and cord blood cells. Finally, we used a proteomic approach to investigate the presence of mHAgs in the syncytiotrophoblast and trophoblast debris shed from first-trimester placenta. By this method, four antigens (DDX3Y; ribosomal protein S4, Y linked; solute carrier 1A5; and signal sequence receptor 1) were found in the syncytiotrophoblast, and one antigen (DDX3Y) was found in shed trophoblast debris. The finding of mHAgs in the placenta and in trophoblast debris provides the first direct evidence that fetal antigens are present in debris shed from the human placenta. The data, thus, suggest a mechanism by which the maternal immune system is exposed to fetal alloantigens, possibly explaining the relationship between parity and graft-versus-host disease.

Abstract
Embriões bovinos produzidos in vitro, em estádio de mórula, foram cultivados em meio contendo anticorpos anti H-Y de alto título proveniente de ratos por 24h e, após este tempo, classificados em dois grupos: 1) embriões inibidos em estádio de mórula (classificados como machos) e 2) embriões que se desenvolveram e formaram a blastocele (classificados como fêmeas). O sexo de 311 embriões, distribuídos em três grupos de concentração dos anticorpos, 3%, 5% ou 7%, foi identificado pela reação em cadeia da polimerase. Não houve desvio da proporção entre machos e fêmeas (P>0,05) nos grupos em que se utilizaram os anticorpos anti H-Y, quando comparadas ao grupo-controle, sem adição de anticorpos anti H-Y. Diferentemente dos resultados obtidos utilizando-se embriões bovinos produzidos in vivo, a sexagem com anticorpos anti H-Y de alto título em embriões produzidos in vitro não propiciou sucesso.

Abstract
Murine and bovine embryos at the late morula stage were cultured in medium containing high-titer rat H-Y antisera. After 12h of incubation, embryos blocked at the late morulae stage were classified as males and those at the blastocyst stage were classified as females. Sexing of murine embryos by PCR and cytogenetics revealed that 83% of the embryos classified as males and 82% of those classified as females had their sex correctly predicted (P < 0.05). Bovine embryos were transferred to recipient females. Pregnancy rates were 71.4% (10/14) for embryos classified as males and 68.8% (11/16) for embryos classified as females. The sex was correctly predicted for 80% (8/10) of the embryos classified as males and for 81.8% (9/11) of those classified as females (overall accuracy, 80.9%, P < 0.05). Therefore, the induction of developmental arrest by high-titer male-specific antisera was an efficient strategy for non-invasive embryo sexing. The procedure was straightforward and has considerable commercial potential for sexing bovine embryos.

Abstract
One hundred primers (Operon kits OPAA, OPAO, OPAV, OPC, and OPE series) were used for random amplified polymorphic DNA (RAPD) fingerprinting to determine male-specific fragments. Seventy-four percent of the primers yielded Yorkshire polymorphic fragments. One of these primers, OPAV-18, produced a novel 1098-bp DNA fragment found only in tested males. This male-specific fragment was isolated and constructed into plasmids for nucleotide sequencing. Two primers (5'-TTGCTCACGG TAGATAACAA GAGAG-3' and 5'-TTGCTCACGG ACCAGGTAGG GAATG-3') were designed according to the cloned male-specific sequence to amplify the male-specific band using polymerase chain reaction (PCR) for pig sexing. Sex-specific bands in the PCR gel products were represented in males but none were found in females when Yorkshire, Duroc, and Landrace genomic DNA samples were amplified with these two primers by PCR. The PCR products in the gel were transferred to nylon membranes and hybridized with a 32P-dCTP labeled probe of the cloned male-specific DNA fragment. There was a clear hybridization signal in samples from all of the male pigs, but not from those of female pigs. Male and female genomic DNA samples from these pigs were spotted onto nylon membranes and hybridized with the male-specific probe. The probe hybridized strongly to males only. A high degree of sequence homology was found among the novel male-specific DNA sequences in Yorkshire, Duroc and Landrace. The sex of these three breeds of pigs could be easily and effectively determined using these two primers.

Abstract
The objective of this study was to compare the overall efficiency, measured by in vitro embryonic survival, and practical value of bovine in vitro embryo production, biopsy, vitrification, and direct transfer technology using 2 different manipulation methods for biopsy. Slaughterhouse-derived oocytes were matured in vitro, fertilized (Day 0) with frozen-thawed, Percoll-separated spermatozoa and cultured on a granulosa cell monolayer. In Experiment 1, one or two blastomeres were expelled from Day 4 embryos by mechanical force through a hole made by partial zona dissection. Using a darning needle hole system for individual culture of biopsied embryos from Day 4 to Day 7.5, the blastocyst per oocyte rate was 50%, and 76% of the blastocysts survived subsequent vitrification and direct in-straw rehydration. Attempts to increase the cell number of the biopsies by further in vitro culture were unsuccessful. In Experiment 2, Day 7 and Day 8 embryos were manually biopsied before or after vitrification. When biopsy was performed before vitrification, 98% of the embryos survived manipulation, and 86% of these re-expanded after vitrification and in-straw dilution. Biopsy after vitrification was less efficient, since only 69% of the embryos survived both processes. The cumulative efficiency of embryo production, Day 7.5 biopsy and vitrification--in-straw direct rehydration was lower (P < 0.001) than that of Day 4 biopsy and Day 7.5 vitrification (29 vs 38%, respectively). However, a Day 7.5 biopsy may have the more practical application since the size of the biopsy is larger and the process is not as time-consuming as the long-term individual culture of the biopsied embryos.
