Regeneration ofthe chick organs and the application for breeding by use of a stem cell

从鸡胚或体细胞中分离保留多能性的干细胞。将获得的干细胞用作制备生殖系和体细胞染色体的供体细胞。胚胎干细胞来源于X期胚盘的透明区。体干细胞来源于骨髓细胞或脂肪细胞。通过胚胎干细胞有效地产生生殖系嵌合体。骨髓细胞或脂肪细胞可再生为静脉、肌肉或骨细胞。由于这些结果，干细胞可能是未来家禽育种的有用工具。

Stem cells which retained pluripotency was isolated from the chick embryos or somatic cells. The obtained stem cells were used as donor cell for making germline and somatic chicmeras. The embryonic stem cells were derived from area pellucida of stage X blastoderm. The somatic stem cells were obtained from bone marrowcells or adipocytes. The germline chimeras were effectively generated by the embryonic stem cells. The bone marrow cells or adipocyte could be regenerated into vein, muscle or bone cells. Due to these results, the stem cells could be useful tools for future poultry breeding.
