Representative astrocyte morphologies in adult cortical areas after in utero StarTrack electroporation at E14.

<p><b>A.</b> Protoplasmic astrocytes. <b>B.</b> Immunohistochemistry against GFAP in brain sections labeled by Star Track. <b>C.</b> Immature astrocytes/progenitors, classified as a subtype of protoplasmic astrocytes. <b>D–E.</b> Pial astrocytes that extend their somas along the pial surface and emit brush cellular processes into the brain parenchyma. <b>F.</b> Radial glia in the ventricular/subventricular zone. <b>G–H.</b> Mesh-forming cells resembling NG2-glia. <b>I.</b> Immunohistochemistry against PDGFRα typically expressed by NG2 cells. <b>J–K.</b> Astrocytes radially arranged around a single blood vessel. Scale bar: 50 µm.
