胚胎形狀 的英文怎麼說
中文拼音 [pēitāixíngzhuàng]
胚胎形狀
英文
embryony-
Embryological studies reveal that megaspore and such cells as egg, synergid and antipodals in mature embryo sac initiate the division of forming haploid plants through embryogenesis or callus formation
胚胎學觀察揭示大孢子與胚囊內的卵細胞、助細胞和反足細胞均有可能在培養中啟動分裂，通過胚狀體或愈傷組織形成單倍體植株。Eg cells of the 2th and 4th passage were akp ( alkaline phosphate ) positive. when cultured on degenerated feeder layers or in suspension, eg c ells formed embryoid bodies ( ebs ) in vitro
當eg細胞脫離飼養層懸浮培養，或在衰老的飼養層上延遲培養時，發現eg細胞或單個存在，或聚集成團，形成類似於早期胚胎的囊狀胚體結構Throughout the culture period, most cells within the colonies continued to be alkaline phosphata se positive and specific stage embryonic antigen ( ssea - 1 ) positive which has been used routinely to characterize embryonic stem and pgcs cells
經過4 7天培養， pgcs形成典型的鳥巢狀集落。集落在傳代過程中保持堿性磷酸酶活性，胚胎階段性特異抗原1 （ ssea - 1 ）免疫熒光染色顯示陽性。Four species of ceratiodes were studied about organic morphology and embryonal development and biological characteristics. the results were showed as follows : c. arborescens and c. ewersmanniana were more dominant than c. latens and c. lanata in spire and vegetative period. in flowering phase of male flower, c. arborescens and c. latens arrive the maximum peak of flowering during 8 : 00 - 11 : 00. c. lanata arrive the maximum peak of flowering during 11 : 00 - 1 : 00, but in flowering phase of female flower, three species arrive the maximum peak of flowering in 14 : 00 ; temperature of female flower was righter than one of male flower
本文對駝絨藜屬4種植物進行了器官形態學及解剖學、胚胎發育及生物學特性的研究，結果表明： ４種材料幼苗期和營養生長期的生長狀況均是華北駝絨藜、心葉駝絨藜比駝絨藜、北美駝絨藜占優勢；開花規律，華北駝絨藜和駝絨藜雄花均在8 : 00 - 10 : 00達開放高峰，北美駝絨藜在11 : 00 - 1 : 00達開放高峰，而三者雌花均在14 : 00左右達開放高峰。Length, diameter, density, fresh weight, dry weight, water content, osmotic potential and element concentrations ( ca, mg, na, k, cl ) were determined for each. seedling of b. gymnorrhiza and a. corniculatum were cultured for 60 days on various salinity of seawater ( 0, 5, 10, 15, 20, 30, 40, 50 ) in green house. samples were taken at 3, 7, 11, 15, 22, 30, 45 and 60 days after planting, separated into root, hypocotyl, stem and leaf
本文研究了福建九龍江口木欖和桐花樹胎生繁殖體從果實形成到發育成熟過程中形態、生物量、含水量、胚軸密度、滲透勢、五種主要礦質元素（ ca 、 mg 、 na 、 k 、 cl ）等的變化和溫室內人工鹽度梯度栽培下木欖和桐花樹成熟繁殖體長成幼苗（ 0 60d ）過程中形態、生物量、含水量、滲透勢、光合蒸騰特性、五種主要礦質元素（ ca 、 mg 、 na 、 k 、 cl ）等的變化；並且在野外自然條件下，跟蹤調查不同灘塗位置下秋茄成熟繁殖體定居成活、自然死亡狀況以及測定幼苗生長過程中（ 1年）形態、生物量、含水量、光合蒸騰特性等的變化。The results showed that, at 12 48 hrs post infection, the bursal epithelial cells bore swollen and necrotic shape. the lymphoid cells in the medulla and cortex of lymphoid follicles had various degrees of degeneration and necrosis. the lymphoid follicles showed glandular structures or cystic vacuoles owing to the prolifetation of bursal epithelium and lymphocyte depletion. lymphoid follicles from bursa at 72 144 hrs post inoculation became atropy. marked proliferation of interfollicular and interstitial connective tissue was present
結果表明，病毒感染后12 48小時，雛雞法氏囊粘膜上皮細胞腫脹、壞死脫落，淋巴濾泡髓質部及皮質部淋巴細胞不同程度變性、壞死、排空，形成腺管樣結構或囊狀空泡，接毒后72 144小時，法氏囊淋巴濾泡淋巴細胞壞死排空，淋巴濾泡萎縮，網狀結締組織大量增生，而胚胎發育時期，法氏囊粘膜上皮腫脹變性，法氏囊淋巴濾泡形成延遲或不完整，淋巴濾泡內淋巴細胞缺乏或空虛。Last fall, for example, researchers from the massachusetts institute of technology and the technion - israel institute of technology reported generating tissues of neural, liver and cartilage cells, as well as formation of a “ 3d vessel - like network ” on a biodegradable polymer scaffold seeded with human embryonic stem cells
舉例來說，去年秋天，美國麻省理工學院和以色列技術學院的研究人員，就提出報告說他們成功製造出神經、肝臟和軟骨細胞組織，並在接種了人類胚胎幹細胞的生物可分解聚合物支架上，形成了立體的管狀網路。It may arise naturally due to mutation in a cell of a developing embryo, producing a line of cells with the mutant gene, and hence different characteristics compared to surrounding cells
嵌合體可以由發育著的胚胎細胞變異而自然形成，這樣就產生了具有不同性狀的變異基因的細胞系。分享友人
