The secondary oocytes from Saanen dairy goats and 4-32 cell embryos from Shaanbei black goats were used as cytoplast donors and karyoplast donors respectively.
選用陝北黑山羊的4 - 32細胞胚和薩能奶山羊的次級卯母細胞分别作核供體和胞質供體。
We first observed that the head ofmature tentacle contained transfer cells which were pellet shape, thickness cytoplast, large nucleolus, developing endoplasm, small vacuole and thick cell wall.
首次觀察到成熟腺毛頭部為具有獨特的内突生長的傳遞細胞,細胞為圓球形,細胞質稠密,細胞核大,内質網發達,液泡較小,細胞壁厚。
The paper mainly reviewed several factors on influencing somatic cloning of pigs, which involve in cytoplast recipients, donor cells, micromanipulation, activation and reconstituted embryo transfer.
因此本文主要綜述了影響體細胞克隆豬的幾個因素,涉及胞質受體、供核細胞、顯微操作、激活以及重組胚移植。
n.|protoplasm;[細胞]細胞質(等于cytoplasm)
cytoplast(胞質體)是細胞生物學中的一個專業術語,指通過實驗手段(如細胞松弛素B處理後的離心去核技術)去除細胞核後,剩餘的完整細胞質部分。它保留了細胞膜、細胞器(如線粒體、内質網、高爾基體等)、細胞骨架、胞質溶膠以及細胞質中的蛋白質、RNA等成分,但失去了細胞核及其包含的基因組DNA。
胞質體在研究中主要用于:

cytoplast 是生物學領域的專業術語,具體釋義如下:
1. 定義與核心概念
指細胞中完整的胞質内容物(intact cytoplasmic content of a cell),即細胞質部分,包含細胞質基質、細胞器等,但通常不包含細胞核。該詞由詞根"cyto-"(細胞)和"-plast"(形成體)組合而成。
2. 發音與詞性
3. 應用場景與例句
在細胞分裂過程中,cytoplast的分裂(胞質分裂)通常發生在核分裂之後。例如:
"The collecting duct is composed of monolayer columnar epithelia with abundant membrane labyrinths in cytoplast."(收集管由單層柱狀上皮細胞構成,胞質内有豐富的膜迷路結構。)
4. 相關術語辨析
5. 擴展知識
在植物細胞研究中,cytoplast常被用于描述去核後的原生質體,這類技術可用于細胞工程和遺傳學研究。
