In this work, we have investigated the role of two crucial morphogens, fibroblast growth factor 10 and sonic hedgehog, in the formation of periodically alternating cartilaginous and non-cartilaginous domains in the ventral mesenchyme. Using a combination of gain- and loss-of-function approaches for FGF10 and SHH, we demonstrate that precise spatio-temporal patterns and appropriate levels of expression of these two signaling molecules in the ventral area are crucial between embryonic day 11.5 and 13.5 for the proper patterning of the cartilage rings. We conclude that the expression level of FGF10 in the mesenchyme has to be within a critical range to allow for periodic expression of Shh in the ventral epithelium, and consequently for the correct patterning of the cartilage rings. We propose that disturbed balances of Fgf10 and Shh may explain a subset of human tracheomalacia without tracheo-esophageal fistula or tracheal atresia.<\/jats:p>","DOI":"10.1242\/dev.051680","type":"journal-article","created":{"date-parts":[[2010,12,10]],"date-time":"2010-12-10T01:50:16Z","timestamp":1291945816000},"page":"273-282","source":"Crossref","is-referenced-by-count":91,"title":["FGF10 controls the patterning of the tracheal cartilage rings via <i>Shh<\/i>"],"prefix":"10.1242","volume":"138","author":[{"given":"Fr\u00e9d\u00e9ric G.","family":"Sala","sequence":"first","affiliation":[{"name":"Developmental Biology and Regenerative Medicine Program, Saban Research Institute of Childrens Hospital Los Angeles, Los Angeles, CA 90027, USA."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pierre-Marie","family":"Del Moral","sequence":"additional","affiliation":[{"name":"Developmental Biology and Regenerative Medicine Program, Saban Research Institute of Childrens Hospital Los Angeles, Los Angeles, CA 90027, USA."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Caterina","family":"Tiozzo","sequence":"additional","affiliation":[{"name":"Developmental Biology and Regenerative Medicine Program, Saban Research Institute of Childrens Hospital Los Angeles, Los Angeles, CA 90027, USA."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Denise Al","family":"Alam","sequence":"additional","affiliation":[{"name":"Developmental Biology and Regenerative Medicine Program, Saban Research Institute of Childrens Hospital Los Angeles, Los Angeles, CA 90027, USA."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"David","family":"Warburton","sequence":"additional","affiliation":[{"name":"Developmental Biology and Regenerative Medicine Program, Saban Research Institute of Childrens Hospital Los Angeles, Los Angeles, CA 90027, USA."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tracy","family":"Grikscheit","sequence":"additional","affiliation":[{"name":"Developmental Biology and Regenerative Medicine Program, Saban Research Institute of Childrens Hospital Los Angeles, Los Angeles, CA 90027, USA."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jacqueline M.","family":"Veltmaat","sequence":"additional","affiliation":[{"name":"Developmental Biology and Regenerative Medicine Program, Saban Research Institute of Childrens Hospital Los Angeles, Los Angeles, CA 90027, USA."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Saverio","family":"Bellusci","sequence":"additional","affiliation":[{"name":"Developmental Biology and Regenerative Medicine Program, Saban Research Institute of Childrens Hospital Los Angeles, Los Angeles, CA 90027, USA."},{"name":"University of Giessen Lung Center, Excellence Cluster in Cardio-Pulmonary Systems, Department of Internal Medicine II, Klinikstrasse 36, 35392 Giessen, Germany."}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"237","reference":[{"key":"2021042607104707600_R1","doi-asserted-by":"crossref","first-page":"1072","DOI":"10.1101\/gad.1171104","article-title":"Interactions between Sox9 and beta-catenin control chondrocyte differentiation","volume":"18","author":"Akiyama","year":"2004","journal-title":"Genes Dev."},{"key":"2021042607104707600_R2","doi-asserted-by":"crossref","first-page":"3","DOI":"10.1046\/j.1460-9592.2003.00802.x","article-title":"Tracheomalacia and bronchomalacia in children: pathophysiology, assessment, treatment and anaesthesia management","volume":"13","author":"Austin","year":"2003","journal-title":"Paediatr.
