Distribution of Cre-positive cell types in P4 Plp-Cre CNS tissues.

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. This is especially true for P4 spinal cord.bCells counted from deep central white matter region of cerebellum.cCells counted in developing region of cerebellar granular, Purkinje and molecular cell layers.a. 存在大概率为Cre阳性（Cre-positive）的细胞，该类细胞可被胶质纤维酸性蛋白（GFAP）与CC-1标记染色。此类细胞被认定为GFAP阳性星形胶质细胞，而非少突胶质细胞，这一特征在出生后第4天（P4）的脊髓样本中尤为显著。 b. 计数细胞采集自小脑深部中央白质区域。 c. 计数细胞采集自小脑颗粒层、浦肯野细胞层（Purkinje cell layer）与分子层的发育区域。
