| 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。

| 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. | E and er are possibly related with metamorphoses of spermatid and sperm maturation
E _ 2和er也可能参与精子细胞的变态和精子成熟的调节。
|
| 5. | 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。
|
| 6. | 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。
|
| 7. | 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。
|
| 8. | 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 。
|
| 9. | 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。
|
| 10. | 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 ） 。
