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.
