Figure Legend Snippet: Schemes of cytoneme-mediated cell signaling based on experimental evidence : (A) Type 1: Receiving cells emit cytonemes to collect the morphogen from producing cells. (B) Type 2: Producing cells emit cytonemes to deliver the morphogen to receiving cells. (C) Type 3: Both producing and receiving cells emit cytonemes to deliver and collet the morphogen respectively. (D) Frame of reference used to develop the mathematical equations. (E) Schematic representation of the cytoneme triangular dynamics. (F) Schematic representation of the cytoneme trapezoidal dynamics.
Techniques Used:
Figure Legend Snippet: (A) Wing imaginal disc cytonemes protruding from A (top left) and from P (top right) compartment cells marked with Ihog-RFP. Bottom panels show 3D reconstructions of a confocal Z-stack taken at the basal side of the tissue showing cytonemes protruding and from A (bottom left) and P (bottom right) compartment cells. (B) A confocal Z-stack taken from the apical to basal side of the abdominal histoblast epithelium with the A compartment marked with life-actin-RFP (red) and the P compartment marked with CD8GFP (green). (C) In vivo temporal sequence of abdominal histoblast cytonemes taken at one-minute intervals. Top image sequences show both A and P compartment labelled cytonemes (A in red, P in green), middle image sequences show a single channel of A compartment cytonemes, and bottom image sequences show the single channel of P compartment cytonemes. (D) Statistical violin plots of cytoneme length distribution in the A (blue) and the P (green) compartments in wing disc (left) and abdominal histoblast nest (right). Scale bars: 15μm.
Techniques Used: In Vivo, Sequencing

(B) Quantified data of the Hh gradient in both epithelia: wing disc (green) and abdominal histoblast nest (blue). (C) Comparison between the wing disc experimental gradient (green) and the predicted gradient estimated by our cytoneme model (blue). (D) Comparison between the abdominal histoblast nest experimental gradient (green) and the predicted gradient estimated by cytoneme model (blue). (E) Comparison between the wing disc experimental gradient (green) and the predicted gradients applying different models: cytoneme model (blue) and diffusion-degradation model (black). (F) Comparison between the abdominal histoblast experimental gradient (green) and the predicted gradients applying different models: cytoneme model (blue) and diffusion-degradation model with different diffusion coefficient (red 3 times smaller than black). Scale bars: 30μm.
Techniques Used: Labeling, Comparison, Diffusion-based Assay
