【Abstract】 Although much progress has been achieved in the last few years, mammalian cloning is still inefficient. Donor cell selection is critical for the success of cloning animal, and it is also an important factor affecting the cloning efficiency. The progress of cloning animal using donor cells of different cell cycle, cell type, cell resource and cell differentiation degree has been summarized.更多还原
