Culture containing leg regenerates (Ir), prothoracic ganglion (ga), and pro- thoracic gland (gl). The leg regenerates are surrounded by partial sheets of epithelial cells (ec). GHal cells (gc) are seen emerging from the cut ends of the nerve of both leg regen- erates and ganglion and forming a cell bridge. In vitro 21 days; transmitted light. Figure 2. Typical growth from the nerve end in a leg regenerate. Sensory axons (ax) emerge from the severed nerve (n) and maintain close contact

Typical growth from the nerve end in a leg regenerate. Sensory axons (ax) emerge from the severed nerve (n) and maintain close contact with several glial cells (gc). In vitro 37 days; dark contrast phase. Figure 3. Schwann-like glial cell (gc) with sensory axon (ax) runnmg along the sur- face. Time-lapse studies show much activity in the region of the growth cone (gr). In vitro 60 days; dark contrast phase. , / n • , u Figure 4 Axon (ax) fibers emerging from ganglion explant (ga) migrate through a break in the neurilemma. Glial cells (gc) containing lipid-filled vacuoles are also emerging.
