Artificial chromosomes are useful in making functional vectors for very large genes, studying chromosome physiology, and modeling chromosomal disorders. Shinohara et al. have succeeded for the first time in creating transchromosomic mice by manipulating spermatogonial stem cells (SSCs), which exhibited superior chromosomal stability compared with embryonic stem cells (ESCs).
人工染色体在构建用于非常大基因的功能性载体、研究染色体生理学以及模拟染色体疾病方面很有用。筱原等人首次通过操纵精原干细胞(SSCs)成功培育出了转基因小鼠,与胚胎干细胞(ESCs)相比,这些小鼠表现出了卓越的染色体稳定性。
