MethodsNeural tubes isolated from the region between midotic placode and third somite of mouse embryo at ED 8.5d were cultured in DMEM/F12 serum-free medium containing basic fibroblast growth factor and epidermal growth factor. The cell cycle of CNCCs was analyzed with flow cytometry, the proliferation capability was determined by MTT method, AP-2α expression was detected by immunocytochemistry as a biological marker of cardiac neural crest cells. The features of migration, multi-directional differentiation were observed as well.

材料与方法成年2月龄C57／BL6小鼠交配，取ED8.5d小鼠胚胎枕中部至第3体节神经管，应用包含碱性纤维生长因子和表皮细胞生长因子的无血清培养基培养，利用MTT法检测细胞增殖能力，利用流式细胞仪检测细胞周期，采用转录激活因子2α(AP-2α，Activator protein-2α)作为其生物学标记物，观察其增殖状况、细胞周期、迁移、分化等生物学特性。

In 10.5 day mouse embryo, by the induction of notochord, mesenchymal cells of ventromedial somite differentiate into sclerotome, cells migrate towards notochord, forming perinotochord tube around notochord, the cartilage is till invisible, alcian dying is faintly positive.

椎体区域发生骨化后（E16.5），阿利辛兰染色呈阴性，茜素红染色呈阳性，仅有Ihh在椎体边缘有表达，无PTHrP表达；在椎间盘区域，仍然保持阿利辛兰染色阳性，仅有PTHrP的表达，无Ihh表达。

The embryo and sperm cell nuclei are stained purple while sperm tails are green.

胚胎和精子细胞核呈紫色，而精子的尾巴是绿色。

This suggests that CaHIRA plays a role in the early embryo development and the late stages. The different expression characters of hira gene in these fish species may be related to the different reproduction models. The research on Drosophila has indicated hira gene related to sperm nucleus decondensation during fertilization. The high expression of hira gene before fertilization is prepared for the sperm nucleus decondensation and the formation of male prenucleus because colored crucian carp is bisexual reproduction. However, the sperm nucleus is not decondensated during the fertilization and is only to activate egg nucleus in gynogenetic gibel carp.

在彩鲫中，从未受精卵到胚胎发育的各个时期均可检测到表达，但表达量发生明显变化，受精后表达量迅速下降，直到原肠胚期表达量有所上升，并一直保持到出苗。hira基因在两亲缘种成熟卵子受精前后表达情况不同，可能与两种鱼不同的生殖方式有关。

Objective:To compare the efficacy of 2 revised long protocols by triptorelin in in vitro fertilization and embryo transfer and intracytoplasmic spermatocyte injection.

目的：比较两种修正的达必佳长方案在体外受精-胚胎移植和卵母细胞单精子显微注射中的作用。

These results indicated that CB is necessary for synchronization in spindle formation in both oocyte and primary spermatocyte, and that synchronization may be required for subsequent embryo development.

这一结果表明CB的处理可以使精母细胞与卵母细胞同步形成MI纺锤体，使其发育同步，这可能对以后胚胎的发育具有重要作用。

Buddhism has it that when spermatozoon combines with ovum, soul is planted into embryo in time, so baby possibly comes into being.

佛教认为，在精子与卵子结合时，神识适时的介入了胚胎之中，如此婴儿才有形成的可能。

It is reported that KAP-1 related transcription regulation complexes exert functions essen-tial for spermiogenesis and early embryo development. This regulation is one pattern of epigenetic regulations.

KAP-1参与形成的复合体在精细胞发育、胚胎早期发育等生理过程中发挥重要的调控作用，这种调控属于表观遗传调控范畴。
