sperm cell 精細胞。

sperm count

The components of 37kd and 39kd glycoproteins from gel were immunized respectively mice and polyclonal antiserums were obtained . glycoproteins of sperm cell surface can be examined using igg rabbit anti mouse - colloidal gold as probe 用它們分別免疫小鼠得到多克隆抗體,以兔抗鼠igg膠體金15nm為探針,檢查此兩種蛋白在精細胞質膜上的分布。

The cells were transplanted into mouse testes and were observed to undergo early meiosis - cell division - the next stage to them becoming mature sperm cells , although they did not develop further 這些細胞被移植到睪丸中,觀察到它們進行了早期減數分裂(細胞分裂) ,下一階段就要變成成熟的精子細胞,盡管他們沒有進一步分化。

Because folate is essential for the synthesis of dna in dividing cells , anything that involves rapid cell proliferation , such as spermatogenesis ( the production of sperm cells ) , requires folate 由于細胞分裂時,葉酸是合成dna的必要因子,任何涉及細胞快速增殖的過程都需要葉酸,例如制造精子。

Human bone marrow has been used to create early - stage sperm cells for the first time , a scientific step forward that will help researchers understand more about how sperm cells are created 人骨髓細胞第一次被分化成早期精子細胞,這項科學進步將幫助研究者更多理解精子起源。

There was expression of cdc2 in nuclear and plasma of spermatogonia , primal spermatocyte , sperm cell , cdc2 also exists in sperm but is fewer than other cells Cdcz在精原細胞、初級精母細胞及精子細胞中的胞漿與胞核中均有表達,精子中也有所表達,但相對淡染

The results showed that distribution of 37 and 39kd peptides on the plasma membrane surface of sperm cells of maize with visible immunogold particles to be localized 免疫定位表明, 37kd , 39kd多肽是玉米精細胞質膜所特異的。有關此多肽的功能有待進一步研究。

Genetic markers showed the presence of partly - developed sperm cells called spermatagonial stem cells , which are an early phase of the male germ cell development 遺傳標記顯示存在部分分化的精子細胞即精原細胞,男性生殖細胞發育的早期階段。

The phosphorylation of cdc2 tyr15 was increased with the age in germ cells 3 . p70s6k was mainly in spermatocyte , sperm cell and sperm 3 . p70s6k主要在精母細胞、精子細胞及精子中有所表達,在不同發育階段細胞內的分布不同。

They cultured these cells in the laboratory and coaxed them into becoming male reproductive cells , which are scientifically known as sperm cells 研究人員在實驗室培養這些干細胞,誘導分化成男性生殖細胞,即精子細胞。

What is known is that as man age , their ability to repair faulty dna in sperm cell decreases 目前所知道的就是,隨著男性年齡的增長,他們修復精液細胞中錯誤dna的能力下降了。

What is known is that as man age , their ability to repair faulty dna in sperm cells decreases 我們所知道的是,隨著男性年齡的增漲,他們修復壞死的dna的精子細胞能力會減弱。

What is known is that as men age , their ability to repair faulty dna in sperm cells decreases 正如我們所知的,隨著年齡的增長,男人修復精液中有缺陷基因的能力會逐漸下降。

What is known is that as men age , their ability to repair faulty dna in sperm cells decreases 我們所知道的是隨著男人的年齡增長,他們能修復精子中錯誤的dna的能力下降了。

The head of the sperm cell and the nucleus of the egg cell then unite and form a new cell : the zygote 然后,精子的頭和卵子的核融合,形成一個新細胞:受精卵。

What is known is that as men age , their ability to repair faulty dna in sperm cells decreases 大家都知道隨著年齡的增加,精子細胞修復dna錯誤的能力相應減弱。

The ovum develops only in the female , and the sperm cell develops only in the male 卵細胞僅在女性體內產生,而精子細胞則僅在男性體內制造。

Without the use of sperm cells 而使卵子受精

Fertilization : only one sperm cell penetrates the outer layer of the egg cell 受精:只有一個精子穿透卵子的外層。

The only reason sperm cells have all the fun is that up until now . . 精子細胞獨攬大權的唯一原因是因為迄今為止. .
