Metric Options: CountsSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
In this study, we improved the protocol for isolating cumulus-oocyte complexes (COCs) from the outbred deer mice by using only one hormone (instead of the widely used combination of two hormones) with reduced dose. Moreover, we identified that significantly more metaphase II (MII) oocytes could be obtained by supplementing epidermal growth factor (EGF) and leukemia inhibition factor (LIF) into the previously established medium for in vitro maturation (IVM) of the COCs. Furthermore, we overcame the major challenge of two-cell block during embryonic development of deer mice after either in vitro fertilization (IVF) or parthenogenetic activation (PA) of the MII oocytes, by culturing the two-cell stage embryos on the feeder layer of inactivated mouse embryonic fibroblasts (MEFs) in the medium of mouse embryonic stem cells. Collectively, this work represents a major step forward in using deer mice as an outbred animal model for biomedical research on reproduction and early embryonic development.
