Commercial embryo flush media with gentamicin sulphate (ABT Complete Flush, ABT 360, Pullman, WA) was utilized for embryo collections when cows were assigned to the AB+ treatment. (auburn.edu)
This sample from the unopened bag of embryo flush media grew Microbacterium testaceum, which was suspected to be an environmental contaminant. (auburn.edu)
Based on study findings, utilization of embryo flush media without added antibiotics may be a viable option for reducing antibiotic use in food producing species. (auburn.edu)
This can be ascribed to the availability of funding and an increase in research activities to improve the culture media across the region, and industry players are introducing disposable devices, such as needles, slides, and chambers, to meet the sterility and regulatory requirements.

Understanding the association between Cell-free DNA levels in embryo CM and the quality of embryo cleavage could help improve the quality of IVF techniques. (who.int)
Methods: This prospective study was conducted with 96 spent CM from patients undergoing IVF cycle, in order to determine relationships of Cell-free DNA levels in embryo CM with embryo cleavage quality on day 3. (who.int)
Day 2 and day 3 CM corresponding to each one of the embryos was analyzed, by quantitative PCR, for estimation of Cell-free DNA levels. (who.int)
Results: The results revealed a significant increase in Cell-free DNA levels on day 2 CM corresponding to 4 to 6 cell embryos compared to those corresponding to 7 to 8 cell embryos (p=0.04). (who.int)
As for day 3 CM, the results showed no significant difference between the Cell-Free DNA levels in CM of 7-8 and those of 4-6 cell embryos (p=0.4). (who.int)
Conclusion: We conclude that cell-free DNA levels in CM might be associated with delayed embryo cleavage. (who.int)

In another strategy, called therapeutic cloning, the embryo can instead be used to create stem cells that are genetically identical to a patient. (nih.gov)
If your white blood cells produce too much ETF, your body's immune system is likely to recognize an embryo as a foreign invader. (sharedjourney.com)
Since the purpose of your white blood cells is to keep your body healthy, your immune system will attack the embryo, causing a miscarriage. (sharedjourney.com)
The first determines whether your cells (or lymphocytes) are producing any type of substance that may be toxic to an embryo. (sharedjourney.com)
Once the fertilized egg divides into additional cells, it becomes an embryo. (nyp.org)

At incubation temperatures lower than 78.8 degrees Fahrenheit, according to the scientists, every embryo will be male. (kpbs.org)

And by moving to a different part of the egg, the researchers wondered, could an embryo could actually influence its sex? (kpbs.org)
It's worth noting that the researchers don't think the embryos were making a conscious choice to become male or female. (kpbs.org)
