In vitro fertilization can be used as an effective treatment for infertility of all causes except for women with infertility caused by an anatomic problem with the uterus, such as severe intrauterine adhesions.
Before you choose an in vitro fertilization clinic for your own fertility treatment, make sure that you know the IVF success rates of the fertility clinics you are considering.

  In vitro meat - Wikipedia, the free encyclopedia
In vitro meat should not be confused with imitation meat, which can be a vegetarian food product produced from vegetable protein, usually from soy or gluten.
In vitro meat may be cleaner and less prone to disease than animals, provided that donor cells are not contaminated.
The in vitro meat would also be exempt from the growth hormones and antibiotics that are used on animals to, respectively, make them grow bigger and fight off the various infections that come from putting so many animals in close quarters for extended periods of time.

 In vitro - Wikipedia, the free encyclopedia
In vitro (Latin: "within glass") is an experimental technique where the experiment is performed in a test tube, or generally outside a living organism or cell.
Alternatives of in vitro include in vivo and in silico: within an organism, and computational, respectively.
This is why results are often annotated with in vivo, in vitro, or in silico, as applies.

 IVF, in vitro fertilization, article   (Site not responding. Last check: 2007-10-16)
In its simplest term, IVF is simply the uniting of egg and sperm in vitro (in the lab).
In vitro fertilization appears to be the most effective treatment for antisperm antibodies, especially when there are very high levels of antibodies (near 100% of sperm are bound by antibodies).
Although this is a controversial subject, one of the largest studies that looked for these antibodies in women undergoing in vitro fertilization found that these antibodies were no more likely to be detected in those who did not become pregnant as in women who did conceive.

 Gale Encyclopedia of Medicine: In vitro fertilization
In vitro fertilization (IVF) is a procedure in which eggs (ova) from a woman's ovary are removed.
The risks associated with in vitro fertilization include the possibility of multiple pregnancy (since several embryos may be implanted) and ectopic pregnancy (an embryo that implants in the fallopian tube or in the abdominal cavity outside the uterus).
In this process of in vitro fertilization, the eggs are fertilized in a laboratory dish and then placed in the woman's fallopian tube.

 Ethical debate: In vitro fertilisation
Modern fertility treatments became the focus of much media attention in 1993 after the widely publicised case in which a 59 year old woman was enabled to give birth to twins by means of in vitro fertilisation with donated eggs and her partner's sperm.
If the success rates of in vitro fertilisation improve, and it is shown that a higher age is not a high personal risk and that old parents are not very damaging then risk-benefit objections to treating older women must be dropped.
When in vitro fertilisation was being developed some 20 years ago I was convinced that future assisted conception units would need ethics committees to consider the more emotive types of fertility treatment that gamete permutation would allow.

 In Vitro Transcription: The Basics
In this article, we present an overview of transcription, including requirements of in vitro transcription reactions and a comparison of conventional vs. large scale RNA synthesis.
The common RNA polymerases used in in vitro transcription reactions are SP6, T7 and T3 polymerases, named for the bacteriophages from which they were cloned.
For antisense RNA to be transcribed the 5' end of the noncoding strand must be adjacent to the +1 G. If the insert is in a vector, the vector should be linearized downstream from the promoter and the inserted sequence to be transcribed (see "Does It Make Antisense?").

 Welcome to The Society For In Vitro Biology
The Society for In Vitro Biology (SIVB) was founded in 1946 as the Tissue Culture Association to foster exchange of knowledge of in vitro biology of cells, tissues and organs from both plant and animals (including humans).
The focus is on biological research, development, and applications of significance to science and society.
Over the years, SIVB has expanded to create an environment of scientific exchange and interdisciplinary synergy with the goal of advancing current and future systems for in vitro biology.

In vitro evolution is a technique used to explore the functional capabilities of RNA and DNA in a rapid, systematic, and directed fashion.
Chemically synthesized DNA is used either directly for DNA experiments or for in vitro transcription to derive a population of RNA.

 In Vitro Translation Systems: The Basics
The in vitro synthesis of proteins in cell-free extracts is an important tool for molecular biologists and has a variety of applications, including the rapid identification of gene products (e.g., proteomics), localization of mutations through synthesis of truncated gene products, protein folding studies, and incorporation of modified or unnatural amino acids for functional studies.
The use of in vitro translation systems can have advantages over in vivo gene expression when the over-expressed product is toxic to the host cell, when the product is insoluble or forms inclusion bodies, or when the protein undergoes rapid proteolytic degradation by intracellular proteases.

MatTek’s EpiDerm™ in vitro human skin model and EpiOcular™ in vitro human corneal model have become increasingly important as replacements for or as complements to traditional animal-based toxicology testing in the cosmetics, personal care, household products, and pharmaceutical industries.
MatTek’s recently developed EpiOral™ human cell-derived in vitro buccal (inner cheek) model and EpiVaginal™ human cell-derived in vitro ecto-cervical vaginal model are also well-suited for cyto-toxicity studies.
Therefore, in a testing strategy that is based purely on in vitro tests, there is a need to combine the basic 3T3 NRU PT with other in vitro tests that allow the safety or phototoxic potency of formulations to be assessed.

It is at this moment, around day seven after fertilization, that pregnancy actually occurs, and this free floating ball of cells finally becomes a part of the mother.
One theory to explain the perplexing phenomenon that most IVF embryos do not result in a pregnancy has been that this thinning of the zona and hatching of the embryo may be defective and some way impeded in embryos that have been cultured in vitro.

The in vitro gas production data and the fermentation parameters indicated a potentially high energy available in cacti species which could explain the relevance of those species in the nutrition of grazing goats in semi-arid regions.
The in vitro gas production technique is a useful tool to determine the nutritional value of the forages consumed by ruminants (Blümmel and Becker 1997) assuming that the volume of gas produced reflects the end result of the fermentation of the substrate to VFA, microbial biomass and neutralization of the VFA.
The objective of this study was to estimate in vitro gas production and its correlation to the chemical composition of browse species consumed by grazing goats in a semiarid region of North Mexico.
