Sentence examples for mouse sperm are from inspiring English sources

Here, we show that most promoters in mouse sperm are flanked by well-positioned nucleosomes marked by active histone modifications.

Although sperm generally maintains fertility for 48 h at cold temperatures, in vitro fertilization rates of C57BL/6 mouse sperm are low after 48-h cold storage.

In the conventional IVF protocol at 1G, mouse sperm are preincubated in vitro with 400 µl of IVF medium for 1 2 h in an incubator at 37°C to develop their fertilization potential (capacitation) [16] and then capacitated spermatozoa are transferred into another 400 µl of IVF medium containing oocytes.

A note of caution for researchers who have not worked with sperm before: mouse sperm are extremely fragile cells.

It is noteworthy that several genes (Adams 1b, 2, 3, 4 and 5) that interact to form functional complexes on mature mouse sperm are among the relaxed/positively selected genes with large average ω branch values (Table  1).

In our experience (Table 1) and in that of others[2] [5], the impaired fertility associated with cryopreserved mouse sperm is dependent on genetic background, with sperm from the C57BL/6 backgrounds being particularly sensitive.
