G-I, K, L) Hts (spectrosomes, red) and p-Mad (germline stem cells, green) staining in control (G), overexpressing (H), and overexpressing (I) germaria show that loss of germline differentiation caused by overexpression is partially suppressed by overexpression is not suppressed by and to express transgenes in escort cells for seven days post eclosion. Nuclei in all samples were stained with DAPI (blue). Scale bar: 20 m. NIHMS1601734-supplement-Suppl__Physique_S2.tiff (16M) GUID:?80B63102-97FF-43A7-818E-9490A36D9120 Suppl. Physique S3: Physique S3: Anti-Dlp or anti-Armadillo detect somatic cells that surround the germline cells.A-C) Anti-Dlp staining of control (A-A), overexpressing (B-B), and overexpressing (C-C) germaria show that somatic cells surround germline cells in control and overexpressing germaria but not in overexpressing germaria. Yellow arrows in A and C show Dlp staining in somatic cells, and yellow asterisk in B shows lack of Dlp staining in overexpressing germaria. D-F) Anti-Armadillo staining in control (D-D), overexpressing (E-E), and overexpressing (F-F) germaria show that somatic cells surround germline cells in control and overexpressing germaria but not in overexpressing germaria. Yellow arrows in D and F show Armadillo staining in somatic cells and yellow asterisk in E shows lack of Armadillo staining in overexpressing germaria. Vasa staining (red in D-F and grayscale in D-F) distinguished germline cells from somatic cells that surround them. G, H) Escort-cell membrane labeling with mCD8::GFP in control (G-G) and overexpressing (H-H) germaria show that escort-cell cytoplasmic processes are lost in overexpressing germaria. All experiments were performed using and to Mouse monoclonal to ELK1 express transgenes in escort cells for seven days post eclosion. Nuclei in all samples were stained with DAPI (blue).

Physique S5: Physique S5: Schematic representation of the SVS tag location at the endogenous locus, and expression and localization in S2R+ cells.A) The artificial exon encoding SVS (StrepII-Venus-StrepII) tag is located between exons 2 and 3 at the endogenous locus. B) S2R+ cells were transiently transfected with (control) or plasmids and stained with anti-GFP to visualize the protein expression and localization under non-permeabilized conditions. (GFP antibody recognizes Venus.) Cell nuclei were stained with DAPI (blue). Scale bar = 20 m. C) Anti-GFP Western blot of cell lysates from transiently transfected control or SVS-dlp overexpressing S2R+ cells, run under reducing or non-reducing conditions. D) Dlp structure: Dlp is usually translated as a single polypeptide, which is usually cleaved by Furin-like convertase giving rise to N- and C-terminal subunits linked by disulfide bonds. Other post translational modifications of Dlp include attachment of GAG (Glycosaminoglycan) chains and a GPI (Glycosylphosphatidylinositol) anchor, both to the C- terminal subunit. Only the SVS-tagged N terminal subunit (~60KDa) of SVS Dlp can be detected under reducing conditions, whereas full length SVS-Dlp that runs as a smear due to GAG chains can be detected under nonreducing conditions. Yellow asterisks in C indicates high molecular weight unprocessed SVS-Dlp. NIHMS1601734-supplement-Suppl__Physique_S5.tiff (4.8M) GUID:?AE571A45-5DAB-4CEB-862B-6252303E24FD Suppl.

NIHMS1601734-supplement-Suppl__Physique_S4.tiff (1.7M) GUID:?4C03B466-A1F6-4E35-9211-4157AF0C978E Abstract Cells in multicellular organisms rely on secreted ligands for development and morphogenesis. Several mechanisms modulate the availability and distribution of secreted ligands, determining their ability to signal locally and at long range from their source. One of these mechanisms is usually Dally-like protein (Dlp), a cell-surface glypican that exhibits biphasic functions in wing discs, promoting Wg signaling at long-range from Wg source cells and inhibiting Wg signaling near source cells. In the germarium at the tip of the ovary, Dlp promotes long-range distribution of Wg from cap cells to follicle stem cells. However, the germarium also expresses other.
