Southern blot of nestin PCR product (490
bp, arrowhead) followed by hybridization with
[32P]dCTP-radiolabeled human nestin cDNA as a probe.
Hybridization was detected in three giant cells (G; lanes 1, 2, and 4),
a TSC neuron (T; lane 6), and a control neuron (N; lane 3). A 490-bp
PCR product was not detected in one giant cell (lane 5).
