Forelimb Regeneration in Reference with Hindlimb Regeneration in Stages of the Egyptian Toad, Bufo Regularis Reuss
Forelimb regeneration was studied in seven larval and metamorphic stages of the toad, Bufo regularis Reuss, after transection at the antebrachium level.
The power of forelimb regeneration at the level of zeugopodium matches with that of the hindlimb at the level of stylopodium within the same stages of the same species.
Fading of the power of regeneration of the extremities of tadpoles in the concerned stages, takes place in a cranio-caudal order along the body axis.
Five-fingered cases appeared only when the early forelimbs were amputated before the hand plate had differentiated its normal four digits.
Syndactyly, when present, took place between fingers 5 and 4 or between 3 and 2 but not in a single case, of the present study, between fingers numbers 4 and 3.
