Dev Genet. 1996;18:234-43 pubmed..The expression of multiple connexin genes during this early period of embryogenesis (when there are only two distinct cell types) raises questions about the functional significance of connexin diversity in this context. ..

Indian J Physiol Pharmacol. 2003;47:147-56 pubmed..In developmentally impaired fetal ovary, only Cx43 was not expressed as expected but other three connexins were expresed. The study may be useful in interpreting human testis defects in infertility cases. ..
