Table 1. Distribution of Cre-positive cell types in P28 Plp-Cre CNS tissues.

	% of CC-1+cells that are Cre+a	% of Cre+cells that are CC-1+a	% of Cre+cells that are Ng2+	% of Cre+cells that are GFAP+a	% of Cre+cells that are NeuN+
Spinal Cord	88.9%±5.4	95.8%±6.8	10.8%±0.7	10.6%±2.2	0
Cerebellum	86.0%±4.8	90.0%±9.2	5.8%±4.3	8.6%±5.8	0
Optic Nerve	91.2%±6.4	88.7%±2.8	3.8%±2.5	3.3%±0.2	n.d.

^aThere are most likely Cre-positive cells which stain for GFAP and CC-1. These cells are assumed to be GFAP astrocytes, and not oligodendrocytes.
