TLDR
Development of two- to four-cell rabbit ova to the expanding blastocyst stage occurred in a simple glucose-salt solution supplemented with amino acids, and with 1.5% BSA as the only macromolecule, suggesting Hypoxanthine and/or thymidine may be inhibitory to good Blastocyst development.Abstract:
SummaryDevelopment of two- to four-cell rabbit ova to the expanding blastocyst stage occurred in a simple glucose-salt solution supplemented with amino acids, and with 1.5% BSA as the only macromolecule. However, optimum growth required the presence of vitamins. These experiments would indicate that although a uterine protein component may be necessary for blastocyst growth and expansion in utero, it is not necessary in the in vitro culture system used. Hypoxanthine and/or thymidine may be inhibitory to good blastocyst development, as the highest percentage of expanding blastocysts (63%) was obtained when the nucleic acid precursors were omitted.Thanks are due to Dr. R. R. Maurer and Mr. M. Simkin for technical assistance.read more

TL;DR: It is indicated that porcine zygotes can develop into blastocysts in a chemically defined medium and to full term by transfer to recipients after culture.

Y. Takahashi,N. L. First +1 more
TL;DR: It is demonstrated that a semi-chemically defined medium can successfully support the development of bovine embryos to the morula stage to a limited extent, but the medium lacks some nutrients or growth factors to fully support development through the blastocyst stage.

TL;DR: The development of suitable non-invasive tests of embryo viability should further increase the overall success of human IVF by the ability to select before transfer those blastocysts most able to establish a pregnancy.

Aspects of in vitro fertilization and embryo culture in domestic animals.
TL;DR: An examination of the spermatozoa and oocyte incubation media showed no media or protein supplement to be superior in promoting in vitro fertilization in cattle, sheep or swine.
