Dorsal closure ( DC ) is a developmental process in which two contralateral epithelial sheets migrate to seal a large hole in the dorsal ectoderm of the Drosophila embryo . Two signaling pathways act sequentially to orchestrate this dynamic morphogenetic process . First , c-Jun N-terminal kinase ( JNK ) signaling activ... | The developmental process of dorsal closure ( DC ) in Drosophila embryogenesis has provided many fundamental insights into conserved mechanisms controlling epithelial dynamics and cell migration , and therefore serves as a model for studying tissue morphogenesis and wound repair .

Chemical and mechanical pattern formation is fundamental during embryogenesis and tissue development . Yet , the underlying molecular and cellular mechanisms are still elusive in many cases . Most current theories assume that tissue development is driven by chemical processes: either as a sequence of chemical patterns ... | During embryogenesis , biological tissues gradually increase their complexity by self-organised creation of diverse chemical and mechanical patterns . Detailed mechanisms driving and controlling these patterns are not well understood . Previous theories mostly assume that these patterns are driven by chemical processes... | [
