spermatogonia 中文意思是什麼

spermatogonia 解釋
精原細胞
  1. During male gametogenesis, the spermatogonia became primary spermatozoa through mitosis, and then became fourth equivalent cytoplasm, round sperm through meiosis. after maturation, they participated in embryo development with the mature oocyte through fertilization. but in female gametogenesis, the primary oocyte formed a matured egg and 1 ~ 3 polar bodies ( pb )

    雄性動物精子發生過程中精原細胞最後一次有絲分裂形成二倍體精母細胞后,經過兩次減數分裂形成了四個含等量細胞質、圓形的精子細胞,最終發育成四個具有正常生理功能的精子,與成熟卵母細胞受精后參與胚胎發育。
  2. Glial cell line - derived neurotrophic factor ( gdnf ) was originally isolated based on its potent and specific ability to promote the survival and morphological differentiation of dopaminergic neurons and motoneurons in embryonic midbrain cultures. in addition, gdnf also support the survival and regulate the differentiation of many peripheral neurons, including sympathetic, parasympathetic, sensory and enteric neurons. gdnf also plays a crucial role outside the nervous system, as a morphogenetic factor in kidney development and as a regulator of spermatogonia differentiation

    Gfr 1與gdnf結合位點的研究膠質細胞源性神經營養因子( gdnf )對多巴胺能神經元、運動神經元、感覺神經元、腸道神經元等多種神經元具有促進存活及保護作用,它還能促進腎臟的發育和精原細胞的成熟,因此,極有希望用於治療神經損傷和神經系統退行性病變。
  3. 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
  4. A variety of biology events occur during spermatogenesis, such as self - renewal of spermatogonia, meiotic division of spermatocyte and the spermiogenesis of spermatid

    生精過程中發生了許多生物學的變化,如精原細胞的自我更新,精母細胞的減數分裂和精子細胞的變形。
  5. 1. with testicular development, the products of c - myc translocate from the cytoplasm of spermatogonia to nuclei of spermatogonia

    隨著精子發育時期的不同, cngc產物在山溪蛻精巢中有從生殖細胞的胞質向胞核中轉移的趨勢。
  6. The results reveal that there are two types of spermatogonium, primary spermatogonia ( sg1 ) and secondary spermatogonia ( sg2 ), in the early developmental stage of testes

    生精細胞之間存在著間橋連接。大眼鱖具有初級精原細胞、次級精原細胞兩種類型精原細胞。
  7. P and pr have relationships with spermatogensis and sperm maturation. 6. the product of c - fos translocates from the cytoplasm of spermatogonia to nuclei of spermatogonia, then it induces the transcription of dna and regulate spermatogonial proliferation and spermatogenesis

    C fos產物從精原細胞胞質中轉移到胞核中后通過啟動dna的轉錄而調控精原細胞的增殖,從而促進精子發生的進程。
  8. The testes of pseudobagurs fulvidraco ( richardson ) can be divided into two parts. the anterior part is spermatogenic part where spermatogenesis proceed. the posterior part of it is the seminal vesicle, which can store sperms and produce large amount of fluid during spawning season. at the end of april, the spermatogenic part of the testes, which is at stage, begin the initiation of spermatogenesis. in may, the spermatogenic part of the testes, which is at stage , starts active spermatogenesis. from june to novermber, the spermatogenic part is at stage, and spermatogenesis is actively proceeding. from december to the beginning of next april, the spermatogenic part is at stage. the wall of the lobulus is made up of cystes of spermatogonia throughout the whole winter time

    黃顙魚的精巢從外形上分為上、下兩段.上段為生精部,下段為貯精囊.性成熟黃顙魚精巢的生精部為小葉型結構,其周年變化經歷如下過程:期?期?期?期?期. 4月下旬開始生精活動的啟動.生殖季節為5 7月, 5月生精部處于期. 6 7月生精部處于期,產生大量精子. 8 11月雖非生殖季節,生精部仍進行生精活動. 12月至翌年4月,生精部處于期,並以期精巢過冬.貯精囊在生殖季節分泌活動旺盛,產生大量分泌物
