...Teng Teng; Camilla S. Teng; Vesa Kaartinen; Jeffrey O. Bush ABSTRACT Tissue fusion frequently requires the removal of an epithelium that intervenes distinct primordia to form one continuous structure. In the mammalian secondary palate, a midline epithelial seam (MES) forms between two palatal...

... slight changes in their shape and orientation can cause debilitating behavioral defects. During development, the canals are sculpted from pouches that protrude from the otic vesicle, the embryonic anlage of the inner ear. In the center of each pouch, a fusion plate forms where cells lose their epithelial...

...Shruti Haralalka; Claude Shelton; Heather N. Cartwright; Erin Katzfey; Evan Janzen; Susan M. Abmayr Myoblast fusion is an intricate process that is initiated by cell recognition and adhesion, and culminates in cell membrane breakdown and formation of multinucleate syncytia. In the Drosophila embryo...

... channels that are active sites of endocytosis. The functions of Kirre and Sns in the embryonic musculature, to mediate adhesion and fusion between myoblasts to form multinucleate muscle fibers, have been conserved in the GCNs, where they contribute to adhesion of GCNs in the `garland' and to their fusion...

..., singly nucleated myoblasts fuse to each other to form myotubes. In muscle growth, singly nucleated myoblasts can also fuse to existing large,syncytial myofibers as a mechanism of increasing muscle mass without increasing myofiber number. Myoblast fusion requires the alignment and fusion of two apposed...

...Sudipto Roy; K. VijayRaghavan ABSTRACT We have investigated the roles of homeotic selector genes in the migration and fusion of myoblasts, and in the differentiation of adult muscle fibres of Drosophila . Altering intrinsic homeotic identities of myoblasts does not affect their segment-specific...

... disappearance of a putative fusion-mediating molecule in the oolemma is proposed. Since this molecule is fairly resistant to proteinase digestion, at least in the hamster, it could be a cryptic protein or a glycolipid. 12 02 1991 © 1991 by Company of Biologists 1991 fusion sperm oocyte...

... of C2C12 cells (a myoblast line derived from adult mouse satellite cells) to araC-treated fiber cultures resulted in their fusion with the rat muscle fibers and restored the ability of the fibers to remodel, whereas addition of either a fibroblast cell line or a transformed, non-fusing variant of C2C12...

...D. M. Juriloff ABSTRACT Cortisone acetate administered to pregnant CBA/J and SWV/Bc mice at 30 to 100 mg kg -1 on day 14 of gestation causes accelerated development of eyelid closure, digit fusion and fusion of pinnae to the scalp on day 16 of gestation. Eyelid closure seems to be accelerated more...

...Jean-Pierre Ozil; Jacek A. Modlinski ABSTRACT Electric-field-induced blastomere fusion was studied in 2-cell rabbit embryos. Field strengths (1 to 3kVcm −1 ) and durations (35 to 1000 μ s) were chosen so as to provide the right balance between fusion rate, viability and developmental capacity...
