| Outline of Final Research Achievements |
Mermaid syndrome is a developmental malformation of the caudal body characterized by leg fusion and associated anomalies of pelvic/urogenital organs including bladder, kidney, rectum and external genitalia. Despite the many clinical studies of mermaid syndrome in humans, little is known about the pathogenic developmental mechanisms that cause the complex array of phenotypes observed. Isl1Cre;Bmp4flox/flox conditional mutant mice displayed mermaid-like phenotypes including hindlimb fusion and pelvic/urogenital organ dysgenesis. Genetic lineage analyses indicated that Isl1-expressing cells contribute to both the aPCM (anterior Peri-Cloacal Mesenchyme) and the hindlimb bud. Furthermore, we show Bmp signaling is essential for the aPCM formation.
