    • Nucleotide sequences described in SEQ ID : NOs. from 1 to 40 are provided to be highly expressed in an early embryonic development stage of avians, thereby being usefully used in order to detect or identify the early embryos in stage X and HH stage 3-9. A method for identifying or detecting embryos in an early embryonic development stage of avians comprises the steps of: (a) obtaining a total RNA from the avian embryo; (b) preparing a cDNA from the total RNA; (c) hybridizing an in vitro transcripted from the avian-embryo derived cDNA or the cNDA obtained from the step(b) with at least one early embryonic-specific polynucleotide sequence selected from the group consisting of SEQ ID : NOs. from 1 to 40, a fragment sequence thereof or a complement thereof; and (d) identifying the hybridization from the step(c). A microarray or a gene amplifying kit for identifying or detecting the embryos in the early embryonic development stage of avians comprises at least one early embryonic-specific polynucleotide sequence selected from the group consisting of SEQ ID : NOs. from 1 to 40, a fragment sequence thereof or a complement thereof. Further, the avian is domestic fowl, quail, turkey, duck, goose, pheasant or dove.
    • SEQ ID NO: 提供从1到40在鸟类的早期胚胎发育阶段高度表达,从而有用地用于检测或鉴定X和HH阶段3-9期的早期胚胎。 在鸟类的早期胚胎发育阶段中鉴定或检测胚胎的方法包括以下步骤:(a)从禽胚获得总RNA; (b)从总RNA制备cDNA; (c)将从禽类衍生的cDNA或从步骤(b)得到的cNDA转录的体外杂交体与至少一种选自SEQ ID NO:1的早期胚胎特异性多核苷酸序列进行杂交。 1至40个,其片段序列或其互补序列; 和(d)鉴定来自步骤(c)的杂交。 在禽类早期胚胎发育阶段中用于鉴定或检测胚胎的微阵列或基因扩增试剂盒包含至少一种选自SEQ ID NO:1的早期胚胎特异性多核苷酸序列。 1至40个,其片段序列或其互补序列。 此外,禽鸟是家禽,鹌鹑,火鸡,鸭,鹅,雉鸡或鸽子。

    • PURPOSE: A method for producing avian chimera using spermatogonial cells and avian chimera produced therefrom are provided, thereby reducing the production time and improving production efficiency than using embryo stem cells because the spermatogonial cells are easily obtained in a large quantity from matured fowls, and mass-produce germline chimera when they are transplanted into the testicle. CONSTITUTION: The method for producing avian chimera using spermatogonial cells comprises the steps of: (a) obtaining the testicle from a donor fowl; (b) isolating the testis cell population from the testicle by treating the testicle tissue with collagenase, trypsin or a mixture thereof; (c) culturing the testis cell population in a medium containing cell growth factor to obtain the spermatogonial cell population; and (d) injecting the cultured spermatogonial cell population or testis cell population into the avian testicle, wherein the cell growth factor is selected from fibroblast growth factor, insulin-like growth factor-1, stem cell factor and a combination thereof.
    • 目的:提供使用精原细胞和禽类嵌合体生产鸟类嵌合体的方法,与使用胚胎干细胞相比,减少了生产时间并提高了生产效率,因为精原细胞很容易从成熟的家禽获得,质量 - 将种系嵌合体移植到睾丸中时产生。 构成:使用精原细胞生产禽嵌合体的方法包括以下步骤:(a)从供体家禽获得睾丸; (b)通过用胶原酶,胰蛋白酶或其混合物处理睾丸组织从睾丸分离睾丸细胞群; (c)在含有细胞生长因子的培养基中培养睾丸细胞群以获得精原细胞群; 和(d)将培养的精原细胞群或睾丸细胞群注射到禽睾丸中,其中细胞生长因子选自成纤维细胞生长因子,胰岛素样生长因子-1,干细胞因子及其组合。
