Fig. 4. Single-cell MARCM clonal analysis of MB gamma neuron development.
(A) Representative image of Fasciclin II (FASII, red) labeled Mushroom
Body containing a single MARCM gamma neuron clone (green). The white box
highlights the area of axonal projection. (B) Developmental profile of
axon projections of single-cell MARCM gamma neuron clones. Boxed insets are
magnifications of areas of small (<5 µm) presynaptic branches
(arrowheads), which are subject to pruning. P3, 60-70 hours APF; P4, 88-96
hours APF; 0-3h, 0-3 hours AE; 4d, 96-112 hours AE. Scale bar: 10 µm.
