" if we wait too long, however, it does n ' t work, so we know that there are multiple regulators in the cell division cycle
負責本次研究工作的加里戈爾博斯基表示: 「我們的研究表明,那些促使細胞分裂的因素是可以被改變甚至是逆轉的」 , 「我們已經知道在細胞分裂的循環周期中有多種調節因素參與其間。Cytoskeleton of a cultured epithelial cell. microtubules are shown in green and dna is shown in blue
處于有絲分裂間期的動物上皮細胞。綠色為微絲,紅色為肌動蛋白,藍色為染色質,中心點復製成兩個。With a little luck, we hoped to coax the early embryos to divide into hollow spheres of 100 or so cells called blastocysts
運氣好的話,我們希望能誘使這些早期胚胎繼續分裂成約100個細胞、狀如中空球體的囊胚。Segregation the separation of the two alleles of a gene into different gametes, brought about by the separation of homologous chromosomes at anaphase 1 of meiosis
分離:同源染色體在細胞減數分裂後期中向細胞極遷移,使等位基因最終分向不同配子。W7 was added when the cells entered anaphase, we found that although some cells had elongated, the distribution patternof cam at central spindle was normal, and it seemed that a cleavage furrow would possibly form soon, however, these cells stopped cytokinesis at this stage, no furrow ingression followed
在細胞進入有絲分裂後期時,加入w7 ,我們發現有的細胞雖已拉伸變長,中區紡錘體處也有gfp cam的分佈,存在形成分裂溝的跡象,但分裂溝卻不繼續縊裂加深。On the other hand, the activity and function of p27 kip1 was affected by many physiological agents such as camp, il - 2, rampamycin. the expression of p27kip1 increased after - irradiationin in the fibroblastoma cells, leading to arrest in gl phase, but its expression markedly decreased after y - irradiation in the nbcc cells, and leaded to arrest in g2 / m phase. several studies have reported that p27 kip1 involved in a much wider range of cellar processes, such as differentiation, apoptosis and migration, the expression level of p27kip1 is key for its function in dna damage responses
另一方面, p27kip 』的活性水平及功能作用,因細胞類型不同而各異,又受多種因素的影響,如一些有絲分裂原camp 、雷帕黴素可以上調p27kip ,的表達,而il一2等則與p27ki 」 『的表達下降有關,受電離輻射( ir )照射的成纖維細胞瘤及用1 , 25一二經基d3處理的hela細胞系在gl期均有游離的p27腳『的積累,細胞周期阻滯在gl期;而在痣癌伽bccs )細胞中, y一射線能誘導p27吻『表達水平的顯著下調,細胞周期阻滯在g2艦期。Their flowers and fruits were removed in this experiment to enhance them to take branch roots on the stems, and then the branch roots were used as materials. five mitosis metaphase cells, with their chromosomes well scattered, were counted. chromosome number of hup is 2x = 24, and its karyotype formula is 2n = 2x = 24 = 8m + 12sm + 4st, being to " 3b " of stebbins
本實驗採取去其花、果實,促其莖節上長側根的辦法,以其側根為實驗材料,統計了5個分散較好的有絲分裂中期細胞,其染色體數目為2x = 24 ,核型公式為2n = 2x = 24 = 8m + 12sm + 4st ,核型類型為3b型。Cultured epithelial cell undergoing division. this cell is in metaphase of mitosis. microtubules are shown in green, actin is in red and mitotic chromosomes are colored blue
