“…60 It also was reported that some toxic substances are eluted from the microfilters that are used for sterilization. 151 Some of this contamination seems to be even inevitable, but care must be taken to minimize it in order to make culture experiments reliable and highly reproducible.…”

“…An analysis of the concentration by using at least a three-level screening design is necessary to understand such responses with the culture medium immediately before use is recommended in some special cases. [151][152][153] Then, the optimal concentration of component B is determined at the optimal concentration of component A. This strategy, which usually has been used, has a big disadvantage of missing the optimal point because there are some unexamined areas in the range of parameters.…”

BackgroundCell culture technology has spread prolifically within a century, a variety of culture media has been designed. This review goes through the history, characteristics and current issues of animal‐cell culture media.MethodsA literature search was performed on PubMed and Google Scholar between 1880 and May 2016 using appropriate keywords.ResultsAt the dawn of cell culture technology, the major components of media were naturally derived products such as serum. The field then gradually shifted to the use of chemical‐based synthetic media because naturally derived ingredients have their disadvantages such as large batch‐to‐batch variation. Today, industrially important cells can be cultured in synthetic media. Nevertheless, the combinations and concentrations of the components in these media remain to be optimized. In addition, serum‐containing media are still in general use in the field of basic research. In the fields of assisted reproductive technologies and regenerative medicine, some of the medium components are naturally derived in nearly all instances.ConclusionsFurther improvements of culture media are desirable, which will certainly contribute to a reduction in the experimental variation, enhance productivity among biopharmaceuticals, improve treatment outcomes of assisted reproductive technologies, and facilitate implementation and popularization of regenerative medicine.

“…Potential risks remain for various medium contaminants, other than albumin, in culture environments, including toxic substances leached from filters used for sterilization, mineral oil [204][205][206], degradation products of components of the medium [207], and ROS generated by light irradiation [56,208,209]. To stably obtain high quality blastocysts in vitro, establishing chemically defined media will not be sufficient, as researchers will also need to strive to optimize the culture system as a whole.…”

Systematic studies of mouse embryo culture beginning in 1949 led to an understanding of essential medium components for early mammalian embryos, and embryo culture from the zygote to the blastocyst stage was achieved in 1968. Since then, medium components that are either beneficial or detrimental for embryo culture have been identified. A variety of culture media that mimic the female reproductive tract, such as human tubal fluid medium and sequential media, were developed from the 1970s to the 1990s, and a single medium in which the concentrations of components were determined by a simplex optimization method was introduced for clinical use in 2002. While either sequential media or a single medium is currently used in most cases, no conclusion has yet been reached as to which of the two approaches is the best. That we are now easily able to culture embryos is the result of the work of pioneers. This review presents a chronological overview of media development from initial attempts at mouse embryo culture using synthetic media to the human embryo culture media used today. It also presents the characteristics of sequential media and a single medium. Finally, problems observed with current embryo culture media are discussed, along with future development in this area.

“…However, the length of aeration necessary before contact material is safe to use varies with the material sterilized and the temperature at which aeration takes place (Schiewe et al, 1990). For example, EtO can be rinsed from syringe filters if sufficient filtrate is passed through before use (Harrison, 1997).…”

In the United States, the Clinical Laboratory Improvement Act (CLIA) of 1988 describes requirements and guidelines for implementing a quality control/quality assurance (QC/QA) program for moderate and high complexity laboratories. These requirements and guidelines apply to Assisted Reproductive Technology (ART) laboratories as well. The general topic of QC and QA as it pertains to in vitro fertilization (IVF) and embryo transfer (ET) is extensively reviewed. This review summarizes many of the QC and QA events that contribute to the advancement of knowledge in this biotechnological field. These events include control of the culture environment inside and outside of the incubator, as well as factors that affect culture media. This review also discusses, in considerable detail, the QC and the QA that pertain to equipment used within the laboratory and how to control for potential contaminants, which reside within the laboratory. This review provides evidence to indicate the need for laboratory personnel to monitor quality improvement issues on a continuous basis. Personnel must be willing to change as improvements in technology occur in order to meet the ever-evolving demands of a more difficult patient population. Suggestions for meeting these demands are offered.
