To clarify if mammalians can be induced to regenerate their limbs like amphibians do, two things were examined in neonatal mice as below. 1) Do skin fibroblasts maintain pattern formation potency? 2) Can the amphibian-type wound epidermis be formed on the amputation stump? In the organ culture system, even in mice, the amputation surface was covered by thin epidermal sheet within a few days, and the morphology of the sheet was similar to the amphibian-type wound epidermis. Those results suggest that the early events of amphibian limb regeneration might be inducible in neonatal mice

为了弄清哺乳动物是否能像两栖动物那样被诱导再生四肢，我们在新生小鼠身上做了如下两项检查。1)皮肤成纤维细胞是否保持模式形成的能力？2)截肢残端能否形成两栖类创面表皮？在器官培养系统中，即使在小鼠中，截肢面也在几天内被薄薄的表皮片覆盖，其形态与两栖类伤口表皮相似。这些结果表明，两栖动物肢体再生的早期事件可能在新生小鼠中被诱导
