| Derivation： | Clonal permanent cell lines with astrocytic or microglial properties have been established from explant cultures of 8-day postnatal mouse cerebella after in vitro spontaneous transformation.
The cell lines were derived in a multistage process. Slowly proliferating foci with several morphologies appeared 4 months after initiation of the cultures and became progressively enriched by cells with a homogeneous appearance. |

| Comments： | Sister flasks of lethally irradiated astrocytes, which are known to synthesize the macrophage-microglia growth factor, M-CSF, were used as a substrate for cloning the cells.
The astrocyte type I cloned cell line named C8-D1A is available as ATCC CRL-2541, the astrocyte type II cloned cell line named C8-S is available as ATCC CRL-2535 and the astrocyte type III cloned cell line named C8-D30 is available as ATCC CRL-2534. The C8-B4 clone expresses classical microglial markers (MAC1, F4/80, 2-4G2) and appears to be derived from a committed microglial precursor since it does not express differentiation antigens present during the early stage of the monocytic lineage. C8-B4 cells synthesize the CD4 molecule and produce and release large amounts of glutamate.

| Complete Growth Medium： | The base medium for this cell line is ATCC-formulated Dulbeccos Modified Eagles Medium, Catalog No. 30-2002. To make the complete growth medium, add the following components to the base medium: fetal bovine serum to a final concentration of 10%.
|
| Subculturing： | Volumes used in this protocol are for 75 cm2 flask; proportionally reduce or increase amount of dissociation medium for culture vessels of other sizes.
Note: Cells do not become confluent.
Subculture Ratio: 1:3 to 1:4 Medium Renewal: 2 to 3 times a week.
Note: For more information on enzymatic dissociation and subculturing of cell lines consult Chapter 10 in Culture of Animal Cells, a manual of Basic Technique by R. Ian Freshney, 3rd edition, published by Alan R. Liss, N.Y., 1994.
