ΥΠΕΡΑΡΙΘΜΟΙ ΑΝΑΓΕΝΝΗΤΙΚΟΙ ΣΧΗΜΑΤΙΣΜΟΙ ΚΑΤΑ ΤΗΝ ΟΝΤΟΓΕΝΕΣΗ ΤΟΥ ΑΚΡΟΥ ΣΤΟ ΑΝΟΥΡΟ BUFO BUFO

IN THE FRAME OF THE RESEARCH OF "PATTERN FORMATION" THE REGULATION OF THE LIMB OF BUFO BUFO ALONG THE PROXIMODISTAL AXIS AND THE CREATION OF SUPERNUMERARY FORMS, WERE STUDIED. FOR THIS REASON WE RESEARCHED THE DISTAL TRANSFORMATION OF THE LIMB IN DIFFERENT STAGES OF DEVELOPMENT AND AMPUTATION LEVELS AND THE INTERCALARY REGENERATION. FURTHERMORE, IN CONTRALATERAL AND IPSILATERAL LIMB BUD GRAFTINGS, SUPERNUMERARY LIMBS WERE PRODUCED AND WERE ANALYSED IN TERMS OF THEIR POSITION OF ORIGIN, FREQUENCY, CARTILAGE AND MUSCLE STRUCTURE AS WELL AS HANDEDNESS ACCORDING TO THE MORPHOLOGICAL AND HISTOLOGICAL DATA. FROM OUR RESULTS: A) WEFOUND THAT THE REGENERATIVE ABILITY OF BUFO BUFO IS LOST GRADUALLY DURING ONTOGENESIS AND ALONG THE PROXIMAL DISTAL AXIS. B) THE SUPERNUMERARY LIMBS WHICH WERE CREATED AFTER 180 DEGREES ROTATION, APPEAR IN STABLE POSITIONS IN THE CIRCUMFERENCE OF THE STUMP AND THEIR MUSCLE STRUCTURE, IS NOTED IN CONTRALATERAL TRANSPLANTATIONS. D) FINALLY, IN THE SERIES OF EXPERIMENTS OF ITERCALARY REGENERATION AND PROXIMAL TO DISTAL AND DISTAL TO PROXIMAL CONTRALATERAL TRANSPLANTATIONS, THERE ARE INDICATIONS THAT PATTERN REGULATION OF CELLS AROUND THE CIRCUMFERENCE OF THE LIMB IS INDEPENDANT ON INTERACTIONS ALONG THE PROXIMODISTAL AXIS.
