Metachromatic leukodystrophy (sulfatide lipidoses) cultured in vitro.

Cerebral white matter from a patient with metachromatic leukodystrophly was successfully cultured in vitro. A luxuriant growth in Rose chambers and in roller tubes was apparent by the 14th day. The outgrown cells contained large numbers of granules which stained dark brown with cresyl violetacetic acid. The growth and metachromasia were maintained up to 80 days in vitro.

In vitro sensitivity of nitrosourea-induced neurogenic tumors to ACNU.

The effect of ACNU on the in vitro viability of a methylnitrosourea-induced gliosarcoma (T9) and two ethylnitrosourea-induced brain tumors, TR-481 (a malignant neurinoma) and EB-679 (a glioma) was studied. T9 was highly sensitive to ACNU, demonstrating loss of cells following a 3 hour exposure time to 5 microgram/ml; TR-481 was sensitive to 40 microgram/ml of ACNU and EB-679 was highly resistant to 40 microgram/ml of ACNU. The in vitro sensitivity of the tumor cell lines to ACNU is: T 9 greater than TR-481 greater than EB-679. This data indicates that variability of response to both concentration and exposure time of ACNU of malignant brain tumor cells must be taken into consideration in planning in vitro and/or in vivo treatment of experimental brain tumors.
