Dpp signalling orchestrates dorsal closure by regulating cell shape changes both in the amnioserosa and in the epidermis.
Fernández BG, Arias AM, Jacinto A. Fernández BG, et al. Among authors: jacinto a. Mech Dev. 2007 Nov-Dec;124(11-12):884-97. doi: 10.1016/j.mod.2007.09.002. Epub 2007 Sep 18. Mech Dev. 2007. PMID: 17950580
During the final stages of embryogenesis, the Drosophila embryo exhibits a dorsal hole covered by a simple epithelium of large cells termed the amnioserosa (AS). ...In summary, we show that Dpp plays a crucial role in coordinating the activity of the AS and i …

Transcriptional activation of hedgehog target genes in Drosophila is mediated directly by the cubitus interruptus protein, a member of the GLI family of zinc finger DNA-binding proteins.
Alexandre C, Jacinto A, Ingham PW. Alexandre C, et al. Among authors: jacinto a. Genes Dev. 1996 Aug 15;10(16):2003-13. doi: 10.1101/gad.10.16.2003. Genes Dev. 1996. PMID: 8769644
The best candidate for a transcription factor that mediates Hh signaling in Drosophila is the product of the cubitus interruptus (ci) gene, a zinc finger protein that exhibits significant homology to protein products of the vertebrate GLI gene family. ...We also sho …

Dynamic actin-based epithelial adhesion and cell matching during Drosophila dorsal closure.
Jacinto A, Wood W, Balayo T, Turmaine M, Martinez-Arias A, Martin P. Jacinto A, et al. Curr Biol. 2000 Nov 16;10(22):1420-6. doi: 10.1016/s0960-9822(00)00796-x. Curr Biol. 2000. PMID: 11102803
BACKGROUND: The adhesion of two epithelial sheets is a fundamental process that occurs throughout embryogenesis and during wound repair. Sealing of the dorsal epidermis along the midline of the Drosophila embryo provides a genetically tractable model to analyse the …

Morphogenesis: unravelling the cell biology of hole closure.
Jacinto A, Martin P. Jacinto A, et al. Curr Biol. 2001 Sep 4;11(17):R705-7. doi: 10.1016/s0960-9822(01)00414-6. Curr Biol. 2001. PMID: 11553345 Review.
Dynamic analysis of dorsal closure in Drosophila: from genetics to cell biology.
Jacinto A, Woolner S, Martin P. Jacinto A, et al. Dev Cell. 2002 Jul;3(1):9-19. doi: 10.1016/s1534-5807(02)00208-3. Dev Cell. 2002. PMID: 12110163 Review.
Throughout development a series of epithelial bendings, sweepings, and fusions occur that collectively give shape to the embryo. ...One well-studied example of such a morphogenetic episode is dorsal closure in Drosophila embryogenesis. This process is tractable at …

Dynamic analysis of actin cable function during Drosophila dorsal closure.
Jacinto A, Wood W, Woolner S, Hiley C, Turner L, Wilson C, Martinez-Arias A, Martin P. Jacinto A, et al. Curr Biol. 2002 Jul 23;12(14):1245-50. doi: 10.1016/s0960-9822(02)00955-7. Curr Biol. 2002. PMID: 12176336
We show that the cable serves a dual role during dorsal closure. It is contractile and thus can operate as a "purse string," but it also restricts forward movement of the leading edge and excess activity of filopodia/lamellipodia. Stripes of epithelium in which cabl …

Planar polarity and actin dynamics in the epidermis of Drosophila.
Kaltschmidt JA, Lawrence N, Morel V, Balayo T, Fernández BG, Pelissier A, Jacinto A, Martinez Arias A. Kaltschmidt JA, et al. Among authors: jacinto a. Nat Cell Biol. 2002 Dec;4(12):937-44. doi: 10.1038/ncb882. Nat Cell Biol. 2002. PMID: 12447392
Dorsal closure is a morphogenetic process involving the coordinated convergence of two epithelial sheets to enclose the Drosophila melanogaster embryo. ...Here we show that actin dynamics at the leading edge is preceded by a planar polarization of the dorsal-most ep …

Actin in development.
Jacinto A, Baum B. Jacinto A, et al. Mech Dev. 2003 Nov;120(11):1337-49. doi: 10.1016/j.mod.2003.06.006. Mech Dev. 2003. PMID: 14623442 Review. No abstract available.
Imaging cell movement during dorsal closure in Drosophila embryos.
Wood W, Jacinto A. Wood W, et al. Among authors: jacinto a. Methods Mol Biol. 2005;294:203-10. doi: 10.1385/1-59259-860-9:203. Methods Mol Biol. 2005. PMID: 15576914
Embryos will survive for several hours mounted on a slide in a gas-permeable oil, such as Voltalef or Halocarbon, during which time they will undergo normal development and can be easily imaged using a confocal laser scanning microscope. Here, we describe in …

The small GTPase Rac plays multiple roles in epithelial sheet fusion--dynamic studies of Drosophila dorsal closure.

The coordinated migration and fusion of epithelial sheets is a crucial morphogenetic tool used on numerous occasions during the normal development of an embryo and re-activated as part of the wound healing response. Drosophila dorsal closure, whereby a hole in the e …
