Mukouyama removed samples of E15.5 mouse limb skin from embryos and stained them with fluorescent labels for ephrinB2 (artery-specific marker); EphB4 (venous-specific marker); and 2H3 (sensory nerve-specific marker). The stained samples were then examined by scanning confocal fluorescence microscopy. Describe the results that were observed (4 pts) The staining pattern of the arterial EC marker co-localized with the pattern of the peripheral sensory nerves, whereras the marker for venous EC did not. State the conclusion that can be derived from these results (use the appropriate evidence terminology: plausibility; necessity; or sufficiency in stating your conclusion).
