| 1. | With systeamine pretreatment decreased yields of dominant lethals were obtained in spermatocytes, spermatids and in spermatozoa . 用半胱氨预先处理,在精母细胞、精子细胞和精虫内均可使显性致死突变值下降。 |
| 2. | With cysteamine pre-treatment, decreased yields of dominant lethals were obtained in spermatocytes, spermatids and in spermatozoa . 用半脘氨预先处理,在精母细胞,精子细胞和精虫内均可使显性致死突变值下降。 |
| 3. | Differentiation of mouse spermatocytes to spermatids during in vitro culture 小鼠精母细胞在体外分化为精子细胞 |
| 4. | On the other hand , various methods of isolation of spermatids from testis are available 另一方面,已经报道了多种不同的方法可从睾丸中分离精子细胞。 |
| 5. | An ongoing clinical pregnancy has even been reported following rosi using frozen - thawed testicular spermatids 甚至已经有采用冻融睾丸组织中精子细胞行rosi后获得持续妊娠的报告。 |
| 6. | As the cells differentiate from spermatogonium to spermatids , the number and size of cb gradually reduce and shrink 随着细胞分化,拟染色质小体逐渐减少直至消失,推测拟染色质小体主要成分为核糖体。 |
| 7. | Whereafter a total of fifteen mouse oocytes were injected with round spermatids and seventeen with elongated spermatids 将获得的小鼠精子细胞进行卵胞质内注射,共穿刺32个小鼠卵子, 15个行rosi和17个行elsi 。 |
| 8. | Ar in interstitial cells probabaly restrain the steriodogenesis of interstitial cells in - situ . ar play a role in metamorphoses of spermatid 间质细胞中的ar可能在原位介导t发生作用,通过负反馈方式抑制间质细胞产生类固醇激素。 |
| 9. | By three days after injection , the number of embryos which had cleaved to the 2 - cell stage was 0 with round spermatids and mree ( 17 . 6 % ) with elongated spermatids 结果在培养的3d中, rosi的卵子没有发生卵裂, elsi的卵子中有3个服至2细胞期o7 6o ) 。 |
