The chiasmata observed during the later stages of the meiotic prophase are cytological evidence of earlier cross-over events.
在減數分裂前期末所看到的交叉是在這以前發生了互換事件的細胞學證據。In the present paper, some investigations on loxoblemmus doenitzi ( gryllidae ) are reported. in order to discover the meiosis of spermatomeres and spermiogenesis, slice - pressing method and improved phenol - fuchsin dyeing method are used. in the course of meiosis, primary spermatocytes directly enter metaphase ii, not through telophase i and prophase ii

未恢復紡錘體的激活卵在解除休克后6min ,卵內染色體開始核化, 9min時形成新的二倍體細胞核, 14min時處入再次分裂的前期, 19min時進入分裂中期, 24min進入分裂後期, 29min時處于分裂末期,且可以看到子核的形成。Cytoskeleton of a cultured epithelial cell. microtubules are shown in green, actin is shown in red and dna is in blue. image by steve rogers
人工培養的動物上皮細胞,目前處于分裂間期。綠色為微絲,紅色為肌動蛋白,藍色為dna (染色質) 。However, the oocytes will arrest the first meiosis at prophase in their follicles. after a long development and acquiring the meiotic resumption competence, oocytes in preovulatory follicles will resume meiosis to mature under the stimulation of preovulatory gonadotropins surge
卵母細胞減數分裂隨之停滯于第一次減數分裂的前期,在卵泡中通過漫長的生長發育過程后,在一定的刺激條件下才恢復減數分裂而成熟。Cytomixis in pollen mother cells usually occured at prophase of meiosis i, but this phenomenon was observed at other stages occasionally
花粉母細胞間染色質穿壁轉移大多發生在減數分裂的前期聯會時期,偶爾也有在其他時期發生的。In this paper, the effect of nuclear actin on the process of chromosome construction has been studied by utilizing the precise natural synchrous plasmodium of physarum polycephalum, sds - polyacryl amide gel electrophoresis ( sds - page ), western blotting, the cell - free system and optics microscopy. the major results and conclusions are as follows : 1
本實驗以多頭絨泡菌原質團為材料,採用同步化培養、細胞核提取、 sds - page 、免疫印跡、非細胞體系構建、光學顯微鏡觀察等方法,研究了有絲分裂前期核內肌動蛋白對染色體構建的影響。In addition, the immediate elf - emf exposure might induce cell cycle arrest, thus also contributing to its stimulating effect of neurogenesis from mesencephalic neural progenitors
此外, elf emfs抑制中腦神經前體細胞增殖,加速神經前體細胞退出細胞分裂周期,可能也是elfL were studied. during the meiotic process of megasporocyte, the ribosome population diminished greatly in prophase i and restored in metaphase i ; plastids and mitochondria turned unclear dedifferentiation in prophase i and recovered their normal structures redifferentiation in metaphase i. all these proved that cytoplasmic reorganization took place during the megasporogenesis of
發現了小麥大孢子母細胞減數分裂過程中,核糖體密度在前期顯著降低,到中期才完全恢復質體和線粒體也出現了脫分化和再分化。從而證明了小麥的大孢子形成過程中也存在著細胞質改組現象。Cultured epithelial cell undergoing division. this cell is in prophase of mitosis. microtubules are shown in green, actin is in red and mitotic chromosomes are colored blue
以上兩圖為正處于有絲分裂前期的動物上皮細胞。綠色的是微絲,紅色為肌動蛋白,染色質高度螺旋成為粗短的染色體(藍色) ,核膜核仁逐漸解體,染色體不規則地分佈於細胞內。After the nuclei of late g2 phase were incubated in the mitotic extracts harvested from metaphase plasmodia, the cyclin b in the nuclei gradually accumulated with the prolongation of incubating time. while, in the control group, the content of cyclin b changed little. this indicated that the mitotic extracts of metaphase plasmodia had the activity of accelerating the process of prophase, and the cell free system with mpf activity was established
將g _ 2晚期細胞核溫育于中期提取物中,免疫印跡結果表明隨著溫育時間的延長,細胞核中cyclinb的含量逐漸增加,而在沒有中期提取物的對照組細胞核中cyclinb含量並不隨著溫育時間的延長而增加,說明多頭絨泡菌中期提取物具有促進有絲分裂前期進程的作用,同時也說明我們構建了具有mpf活性的非細胞體系。This is a very ambitious but potentially far more comprehensive and long - term approach to combating cancer than anything currently available or in development : total elimination of the genes for telomerase and alt ( alternative lengthening of telomeres ) from all of our mitotic cells
這是一次很有雄心的、但比起目前已有的或正在發展中的與癌癥戰斗任何方法,都潛在地遠為廣泛和長期的方法:從所有我們有絲分裂細胞中全部剔除端粒酶基因和消除alt (端粒變長的另一種途徑) 。B - actin primers : forward 5tcc tat cgg cct cct cct ac 3 " and reverse 5aga atg tag tcc gcc agg tc 3 ", designed for 200bps. saodn oligodeoxynucleotide of pkb : stac agc ctg aga gga cct acc tg3 "
在有絲分裂期, edc25經歷216位ser磷酸化同時其水解酶活性增強,活化的mpf磷酸化並活化edc25 ,形成正反饋,結果進一步活化mpf前體,活化的mpf促進細胞周期g2 / m期轉換。As cyclin b is the mark protein representing the process of prophase, we infered that cytochalasin b destroyed the polymerization of the nuclear actin and directly affected the process of prophase. nuclear actin played an important role in the process of the chromosome construction
因為cyclinb是有絲分裂前期進程的標志性蛋白,所以我們認為細胞鬆弛素b破壞細胞核內肌動蛋白聚合后,直接影響了有絲分裂前期的進程,進而悅明核內肌動蛋白在有絲分裂前期染色體構建過程中起著重要作用。Upon the differentiation induction of 3t3 - l1 preadipocytes by hormone cocktail containing 1 - isobutyl - 3 - methylxanthine, dexamethasone and insulin, the preadipocytes undergo ~ 2 rounds of mitotic clonal expansion, which just precedes the adipogenic gene expression program and has been thought to be an essential early step for differentiation initiation
誘導分化的早期細胞會進行約兩輪的細胞分裂,被稱為克隆擴增。克隆擴增以前一直被認為可能有利於染色體的重構以易化分化所需要的基因表達,因此克隆擴增可能是3t3 l1前脂肪細胞分化所必需的過程。Cyclin b can be a kind of mark protein which represents the process of prophase
細胞核中cyclinb的含量變化可以作為有絲分裂前期進程的標志。分享友人
