HC dendritic tips are not stabilized by MG contacts. A, Time-lapse series of a single HC (grayscale) in the gfap:GFP fish (MGs, pink). Images were acquired every 6 h for 48 h beginning at 73 hpf. Stable tips are indicated by green arrowheads, transient tips by red arrowheads, and newly formed tips are indicated by open arrows. Scale bar, 5 μm. B, Lifetime of HC dendritic tips that appeared and disappeared during the 36 h time lapse. C, Time course of when stable HC dendritic tips become associated with MG processes during the recording period. x-axis, Time taken for MGs to contact the dendritic tip after the tip first appeared during the time lapse.
