Astrocyte and satellite cell response to ISP and the adhesion assay
a, Purified GFAP-positive mature astrocytes (green) did
not respond to ISP. b, S100-positive satellite glia were able to cross the gradient
of CSPG after ISP treatment. Scale bar, 50 mm. c, d, Response of neurons and
axons upon a CSPG-rich substrate to agitation after ISP treatment. Scale
bar, 50 mm.
