| 释义 | uteri plural ofuterus Examples of uteriuteri The present study has shown that developing larvae within the uteri gradually stretch the egg membrane to form their cover or sheath. What are the rights of women whose uteri are to be used for gestating clones? The uteri of pseudopregnant females were examined for fetuses on day 19 or 20. These two populations were selected because they offered the largest worm variability (different stages of maturity, body size and gravid uteri). The occurrence of a high proportion (35.4%) of female worms with no eggs in their uteri is not easily explained. Embryos at different stages collected from oviducts or uteri were transferred into a flushed oviduct of non-pregnant mice. All adult whales were found pregnant by the presence of a fetus in their uteri. The worm uteri were distended with eggs, and uterine egg counts of 10 worms showed a mean of 243 ^ 6 eggs/worm. For experiment 2 (see below), primary cell cultures of rabbit fetal fibroblasts were derived from 12-day-old fetuses removed from rabbit uteri by caesarean section. All recipients were laparotomised 9-20 days after transfer to examine the number of swellings in the uteri (implantation sites). Uteri of female worms contain eggs, developing larvae as well as microfilariae varying in number between 180,000 and 220,000. Thereafter, the paired uteri gradually broaden and run almost parallel occupying the greater part of the length of the worm to the anterior region where they gradually narrow. The ovaries, which are blind-ended and strongly coiled, are located near the posterior end of the adult worm and lead into the oviducts which widen abruptly into the uteri. On day 59, the development of branched uteri containing many fertile immature eggs in a worm was observed and by day 75, three worms showed similar stages of development. Ratio of wet weights are averaged over all litters or uteri at each age. These examples are from corpora and from sources on the web.
