A micro-fabricated device (microICSI) improves porcine blastocyst development and procedural efficiency for both porcine intracytoplasmic sperm injection and human microinjection.

[PMID: 38236552 PMCID: PMC10894805 DOI: 10.1007/s10815-023-03018-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/04/2023] [Accepted: 12/21/2023] [Indexed: 01/19/2024] Open
Abstract
PURPOSE Intracytoplasmic sperm injection (ICSI) imparts physical stress on the oolemma of the oocyte and remains among the most technically demanding skills to master, with success rates related to experience and expertise. ICSI is also time-consuming and requires workflow management in the laboratory. This study presents a device designed to reduce the pressure on the oocyte during injection and investigates if this improves embryo development in a porcine model. The impact of this device on laboratory workflow was also assessed. METHODS Porcine oocytes were matured in vitro and injected with porcine sperm by conventional ICSI (C-ICSI) or with microICSI, an ICSI dish that supports up to 20 oocytes housed individually in microwells created through microfabrication. Data collected included set-up time, time to align the polar body, time to perform the injection, the number of hand adjustments between controllers, and degree of invagination at injection. Developmental parameters measured included cleavage and day 6 blastocyst rates. Blastocysts were differentially stained to assess cell numbers of the inner cell mass and trophectoderm. A pilot study with human donated MII oocytes injected with beads was also performed. RESULTS A significant increase in porcine blastocyst rate for microICSI compared to C-ICSI was observed, while cleavage rates and blastocyst cell numbers were comparable between treatments. Procedural efficiency of microinjection was significantly improved with microICSI compared to C-ICSI in both species. CONCLUSION The microICSI device demonstrated significant developmental and procedural benefits for porcine ICSI. A pilot study suggests human ICSI should benefit equally.

Viability of ICSI oocytes after caffeine treatment and sperm membrane removal with Triton X-100 in pigs. Theriogenology 2012; 76:1658-66. [PMID: 21855983 DOI: 10.1016/j.theriogenology.2011.06.030] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/05/2011] [Revised: 06/24/2011] [Accepted: 06/25/2011] [Indexed: 11/24/2022]
Abstract
Non-adequate decondensation of injected sperm nucleus is one the main problems of intracytoplasmic sperm injection (ICSI) in porcine. With the aim of improving pronuclear formation, the effects on activation and embryo development rates of 0.1% Triton X-100 (TX) sperm pre-treatment for membrane removal and/or 5 mM Caffeine (CAF) addition in oocyte manipulating and culture medium for 2 h after ICSI or artificial activation were studied. The effects of 4 different Ca(2+) concentrations contained in the injection medium on embryo development after sham injection were also analysed. In Experiment 1, no significant effect on cleavage or blastocyst rate was detected independently of Ca(2+) concentration contained in the injection medium. In Experiment 2, oocytes injected with TX pre-treated sperm showed a significant higher rate of male pronuclear formation in comparison with oocytes from control group (2PN; 54.1 vs 36.6%). However, no differences on in vitro embryo development, cleavage or blastocyst rates were observed. In Experiment 3, oocytes treated with CAF during and after micromanipulation and injected with sperm pre-treated with TX had a significantly lower oocyte activation rate than any other experimental groups (25.7 vs 56.3-66.3%). No differences were observed in cleavage rates among different experimental groups. However, the CAF group showed a higher blastocyst rate significantly different from TX+CAF group (12.0 vs 1.9%, respectively). In a second approach, the effect of electric field strengths and CAF treatments on oocyte activation was studied. In Experiment 4, oocytes submitted to 0.6 kV/cm showed significant higher activation rates than 1.2 kV/cm ones regardless of the caffeine treatment (83.7 vs 55.9% and 75.7 vs 44.3%; in control and caffeine groups, respectively). No effect of caffeine treatment was observed in any experimental group. In conclusion, TX sperm treatment before ICSI without an additional activation procedure improved male pronuclear formation, but did not improve embryo development until blastocyst stage. No significant effect of caffeine was found when sperm was not treated with TX, although in membrane absence caffeine avoided oocyte activation and embryo development. Finally, caffeine had no effect on female pronuclear formation regardless of electric field strengths applied to the parthenogenetic activation.

Abstract
This case reports a successful live birth by intracytoplasmic sperm injection (ICSI) following human follicular fluid (HFF) centrifugation for oocyte retrieval in the modified natural cycle of a poor responder patient. A 37-year-old patient presenting with a severe ovarian defect underwent a modified natural cycle with HFF centrifugation prior to ICSI. As there was only one oocyte under direct binocular observation, HFF was centrifuged and a second oocyte was collected. ICSI was performed on both oocytes. Embryo quality and outcome were not compromised by HFF centrifugation. A live birth was achieved in April 2008. In a modified natural cycle, HFF centrifugation avoided loss of oocytes, optimized the IVF treatment, and achieved the development of two embryos.

Abstract
Intracytoplasmic sperm injection (ICSI) is a powerful technique in the field of assisted reproduction (ART) and provides exciting opportunities for studying the basic mechanisms of fertilization and early embryo development. Nevertheless, its application in agriculture and conservation biology has been greatly hampered by the low success rate reported for this method in respect of economically important species. Specifically, the rates of blastocyst formation and live newborn are greatly reduced when zygotes are generated by ICSI. Except for humans, ICSI remains a low efficiency technology in comparison with alternatives such as in vitro fertilization (IVF) and its application is less widespread. In this paper, we discuss the present status, applications and factors affecting ICSI in pigs and other species.

Abstract
As a method of producing transgenic animals, spermatozoa have been used to fertilize mammalian oocytes through natural copulation, artificial insemination (AI), and in vitro fertilization (IVF). Our objective was to produce live piglets expressing the enhanced green fluorescent protein (eGFP) by the modified ICSI procedure based on Yong et al. (2003) (Hum. Reprod. 18:2390) where this procedure resulted in an improvement in development in vitro as compared to conventional ICSI and IVF. After injecting frozen-thawed sperm, recovered from the descendant of a transgenic boar derived by oocyte transduction, into in vitro matured oocytes the injected oocytes were surgically transferred into the oviduct of six surrogate gilts. Two gilts (33%) became pregnant. One gave birth to a healthy male piglet. Expression of the eGFP was easily observed in the nose and hooves by direct epifluorescent examination in the newborn piglet. These results show the production of the first viable transgenic piglet by in vitro maturation and our new sperm injection method.

Abstract
The effects of cumulus cell removal and centrifugation of maturing bovine oocytes on nuclear maturation and subsequent embryo development after parthenogenetic activation and nuclear transfer were examined. Removal of cumulus cells at 4, 8, and 15 hr after in vitro maturation (IVM) or the centrifugation of denuded oocytes had no effect on maturation rates. Oocytes treated at 0 hr of IVM had a lower expulsion rate (50%) of the first polar body (PB1). The removal of cumulus cells and centrifugation affected the pattern of spindle microtubule distribution and division of chromosomes. There were almost no spindle microtubules allocated to PB1 and the spindles were swollen in anaphase I and telophase I oocytes. Approximately 20% of PB1 oocytes contained tripolar or multipolar spindles. After activation, oocytes denuded with or without centrifugation at 8 hr of IVM resulted in the lowest rate of development (3.0%). Denuded oocytes at 4, 15, and 24 hr of IVM with centrifugation or not resulted in similar blastocyst development rates (9.6%-13.2%). However, centrifugation of oocytes denuded at the beginning of IVM resulted in lower blastocyst development rate (8.1%, P < 0.05) than the noncentrifuged oocytes (17.3%). After nuclear transfer, the blastocyst development rates of oocytes denuded and centrifuged at 0, 4, and 8 hr of IVM were not different when compared to the same patch of noncentrifuged oocytes. However, oocytes denuded and centrifuged at 15 hr of IVM resulted in lower (P < 0.05) blastocyst development rates than the noncentrifuged oocytes. The results of this study suggest that removal of cumulus cells and centrifugation of denuded oocytes affect the spindle pattern. Embryo development of denuded and centrifuged oocytes may differ depending on the time of removal of cumulus cells.
