最近，美国退役橄榄球明星汤姆·布雷迪引发了一场舆论风波。不过，这次让他获得关注的不是球，而是狗。 11月4日，生物技术公司Colossal Biosciences发布一则声明。声明中，布雷迪透露自己现在的比特犬Junie就是由该公司的克隆服务"复制"出来的。Junie的 前身是他与前妻共同抚养的Lua，已经于2023年死亡。 消息一出，不同舆论相继出现。支持布雷迪的人表示，克隆服务不失为一种面对爱宠死亡的新应对方式。反对者则讽刺道，克隆出来的动物和原动物根本 是两回事，这不过是有钱人自欺欺人的自我感动罢了。 那么，宠物克隆服务的真相到底是什么样呢？ 让布雷迪爱犬"死而复生"的是一种名为"体细胞核移植"的技术。体细胞核移植其实一点也不神秘，早在1996年，科学家就是用这种手段创造出了克隆羊多 莉。我们可以大致将其简化为三步。 多莉是人类用体细胞核移植技术克隆出的第一只哺乳动物，它的标本目前在苏格兰国家博物馆展出（图片来源：Wikipedia by Toni Barros） 第一步，从想要克隆的动物身上提取体细胞（皮肤、耳部、脂肪等），然后取出体细胞的细胞核。细胞核可以说是整个克隆的关键，因为它里面几乎含有 个体 ...

Core Viewpoint - The pet cloning industry, represented by companies like Xino Valley Biotechnology, is facing significant challenges, including customer dissatisfaction, high costs, and a lack of regulatory oversight, raising questions about the ethical implications of such services [1][14][16]. Company Overview - Xino Valley Biotechnology is a leading player in the pet cloning industry, claiming to be the first domestic company with fully independent intellectual property rights in commercial pet cloning and international leading technology in gene editing for dogs [9][12]. - The company has reportedly generated annual revenue of around 20 million yuan (approximately 2.8 million USD) from its pet cloning business, with a projected market potential of 40 million USD in the coming years [12]. Customer Experience - Customers, such as Ding Ying, have reported long wait times and unsuccessful cloning attempts, with some waiting over three years without receiving their cloned pets [2][3]. - The company has faced multiple contract disputes and has been criticized for its lack of communication and transparency regarding the cloning process and outcomes [3][13]. - Customers have expressed frustration over the company's changing personnel and the difficulty in obtaining refunds or updates on their cloning services [3][4][13]. Industry Challenges - The pet cloning industry is characterized by several issues, including exaggerated claims about cloning success rates, inconsistent welfare standards for surrogate animals, and a lack of a comprehensive industry certification system [15][16]. - The average success rate for pet cloning is around 30%, with reputable institutions achieving rates above 40%, but the industry still lacks specific regulatory frameworks to ensure quality and ethical practices [14][15]. Financial Aspects - The cost of cloning services is substantial, with prices ranging from 132,000 yuan (approximately 18,500 USD) for cats to 280,000 yuan (approximately 39,500 USD) for small dogs, and up to 380,000 yuan (approximately 54,000 USD) for larger breeds [7][8]. - The company requires full payment upfront for all services, and there are uncertainties regarding refund policies in the event of service failure, with potential deductions for costs incurred during the cloning process [8][12]. Ethical Considerations - The intersection of technology and emotional attachment in pet cloning raises ethical questions about the value placed on life and the implications of commodifying such services [16]. - Experts suggest the need for improved industry standards and ethical guidelines to ensure responsible practices in the pet cloning sector [15][16].
