The regeneration of heteroplastic chimerical forelimbs of Triturus vulgaris and Triturus cristatus*
During the early tail bud stage, forelimb buds were mutually exchanged between the two species. After transplantation, the host's mesectoderm migrated into the buds. This resulted in forming periclinal-chimerical limbs consisting of donor ectoderm, host mesectoderm and donor mesoderm. As a result, the pigmentation was host-specific and epidermis and mesoderm as well, donor-specific. Consequently shape and epidermal surface of the transplants were donor-specific. Such limbs regenerated with donor specific shape and epidermis, but host-specific pigmentation. This is a proof that the sources of regeneration cells remain germ-layer-specific and also that mesectoderm has its own mesectodermal origin.
