[PMID: 36359181 PMCID: PMC9654503 DOI: 10.3390/ani12213057] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/26/2022] [Revised: 10/21/2022] [Accepted: 10/27/2022] [Indexed: 09/19/2023] Open
Abstract
Supplementation of the culture media for in vitro production (IVP) of bovine embryos with fetal bovine serum (FBS) is associated with inconsistent outcomes. The present study sought to replace FBS and BSA by insulin-like growth factor 1 (IGF1), fibroblast growth factor 2 (FGF2) and epidermal growth factor (EGF). In Experiment 1, absence of FBS from maturation medium (MM) did not affect the rate of in vitro maturation, as assessed by the extrusion of the first polar body. However, when gonadotropins and FBS were removed from the MM, the maturation rate was significantly reduced even in the presence of growth factors. Therefore, gonadotropin-supplemented MM medium was established as the base medium for the defined maturation condition. In Experiment 2, the addition of growth factors to gonadotropin-supplemented MM medium supported similar maturation (~90%) compared to the undefined condition (FBS-carrying). In Experiment 3, the addition of growth factors to embryo culture medium showed similar in vitro competence compared to the undefined (FBS) control. In Experiment 4, completely defined conditions (absence of FBS and BSA during in vitro maturation and embryo culture) were tested. A higher cleavage was observed with FGF2 (86%) compared to EGF (77%) and the FBS control (77%), but similar blastocyst rates were observed for FGF2 (24%), EGF (19%) and the FBS control (25%). Embryo quality was similar among groups. Finally, post-thawing survival was higher for FGF2 (94%) compared to the FBS control (77%). Thus, we report a simple defined IVP system for bovine species that generates developmental outcomes and embryos of similar quality than those produced under conditions containing FBS.

Lee DY, Lee SY, Yun SH, Jeong JW, Kim JH, Kim HW, Choi JS, Kim GD, Joo ST, Choi I, Hur SJ. Review of the Current Research on Fetal Bovine Serum and the
Development of Cultured Meat. Food Sci Anim Resour 2022; 42:775-799. [PMID: 36133630 PMCID: PMC9478980 DOI: 10.5851/kosfa.2022.e46] [Citation(s) in RCA: 28] [Impact Index Per Article: 14.0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/04/2022] [Revised: 08/12/2022] [Accepted: 08/15/2022] [Indexed: 11/19/2022] Open
Abstract
The purpose of this review is to summarize studies that investigate blood and the
main components of fetal bovine serum (FBS) in vertebrates, including major
livestock, and review the current research on commercializing cultured meat.
Detailed research on FBS is still lacking; however, some studies have shown that
FBS consists of proteins, carbohydrates, growth factors, cytokines, fats,
vitamins, minerals, hormones, non-protein nitrogen, and inorganic compounds.
However, there are few studies on how the composition of FBS differs from blood
or serum composition in adult animals, which is probably one of the main reasons
for not successfully replacing FBS. Moreover, recent studies on the development
of FBS replacers and serum-free media have shown that it is difficult to
conclude whether FBS has been completely replaced or serum-free media have been
developed successfully. Our review of the industrialization of cultured meat
reveals that many basic studies on the development of cultured meat have been
conducted, but it is assumed that the study to reduce or replace ingredients
derived from fetuses such as FBS has not yet been actively developed. Therefore,
developing inexpensive and edible media is necessary for the successful
industrialization of cultured meat.

Demands for carbohydrates as major energy substrates depend on the preimplantation developmental stage in pig embryos: differential use of fructose by parthenogenetic diploids before and after the 4-cell stage in the pig.

Abstract
The embryo culture technique has been improving, but the detailed demands for energy substrates such as glucose, fructose, pyruvate and lactate of preimplantation embryos are still unclear. In the present study, the demands of pig preimplantation embryos at each different developmental stage were investigated by use of parthenogenetic diploids as a model of pig preimplantation embryos. Pig parthenogenetic diploids showed different use of glucose and fructose before and after the 4-cell stage. Although glucose supported the development of pig embryos throughout the preimplantation stages and even maintained the expansion and hatching of blastocysts, it suppressed development to the blastocyst stage when glucose coexisted with pyruvate and lactate from 4 h after activation, but not after 48 h (early 4-cell stage). Since ketohexokinase that metabolizes fructose was not expressed in 2-cell and 4-cell diploids, a medium that included only fructose as a major
energy substrate did not support early cleavage of pig diploids beyond the 4-cell stage, and almost no diploids developed to the morula stage just as in a medium without carbohydrates. These results may explain the different suppressive effects on pig preimplantation development between glucose and fructose when pyruvate and lactate were present in a medium. In addition, 4-cell diploids that had been cultured in a medium with pyruvate and lactate developed to the expanded blastocyst stage without any carbohydrates as a major energy substrate. These results show that the demands for carbohydrates are different depending on the developmental stage in pig preimplantation embryos.

The beneficial effect of fructose and glucose on in vitro maturation and the fertilization of porcine oocytes. Reprod Med Biol 2008; 8:19-24. [PMID: 29699303 DOI: 10.1007/s12522-008-0003-8] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/02/2008] [Accepted: 10/10/2008] [Indexed: 10/21/2022] Open
Abstract
Purpose This study was conducted to investigate the effects of supplementing fructose in the culture medium on in vitro maturation (IVM), in vitro fertilization (IVF), and metabolism of porcine oocytes. Methods Porcine oocytes were matured in vitro in modified North Carolina State University 37 medium (NCSU-37) and then supplemented with either glucose (5.5 mM), fructose (5.5 mM), or glucose (2.75 mM) plus fructose (2.75 mM). The maturation and fertilization of oocytes, and the incorporation and oxidation of 14C-glucose, 14C-fructose, and 14C-methionine in oocytes at different stages of development were examined. Results The supplementation of glucose plus fructose significantly promoted (P < 0.05) oocytes germinal vesicle break down (GVBD), maturation to metaphase II (MII), penetration by spermatozoa, and male pronuclear formation compared with glucose. The incorporation and oxidation of 14C-methionine into the oocyte significantly increased (P < 0.05) with glucose plus fructose supplementation than glucose. A significantly higher (P < 0.05) rate of incorporation and oxidation was achieved with 14C-fructose compared to 14C-glucose. Conclusions Glucose plus fructose supplementation improved maturation, penetration by spermatozoa, male pronuclear formation, and energy metabolism by porcine oocytes.
