Upon thawing, the conversion of the liquid nitrogen back to its gas phase may result in the vial exploding or blowing off its cap with dangerous force creating flying debris. One clone with microglial properties named C8-B4 is available as ATCC CRL-2540. For cultures that require storage in liquid nitrogen, it is important to note that some vials may leak when submersed in liquid nitrogen and will slowly fill with liquid nitrogen. However, the underlying mechanisms of these cytokines secreted by astrocytes on PMN formation in lung cancer brain metastases remains to be further exploration. 1321N1 is a human astrocytoma cell line isolated in 1972 as a sub clone of the cell line 1181N1 which in turn was isolated from the parent line U-118 MG (one of a number of cell lines derived from malignant gliomas by J Ponten .1321N1 has been shown to have very similar STR profile data to U-118 MG.
