Tissue culture and transplantation techniques can be used to analyse the relationship between ageing and cancer. In vitro transformation experiments show that the transformation frequency in mesenchymal cells and salivary gland epithelium does not seem to be age-associated but in the bladder old epithelium can be transformed much more frequently than young. Preliminary transplantation experiments confirm this relationship. These experiments suggest that the increased age susceptibility is tissue dependent.
组织培养和移植技术可用于分析衰老与癌症之间的关系。体外转化实验表明，间充质细胞和唾液腺上皮细胞的转化频率似乎与年龄无关，但膀胱中衰老上皮细胞比年轻上皮细胞更容易发生转化。初步移植实验证实了这种关系。这些实验表明，年龄易感性增加是组织依赖性的。
