Source: Lin, G. L. et al., A Protocol for Rapid Post-mortem Cell Culture of Diffuse Intrinsic Pontine Glioma (DIPG). J. Vis. Exp. (2017)
This video demonstrates the process of isolating and culturing glial progenitor cells from diffuse intrinsic pontine glioma, or DIPG-affected brainstem tissue. Glial cells isolated from tumor tissue via an enzymatic digestion are cultured in a neurobasal medium, which promotes their growth and the development of free-floating neurospheres.
All procedures involving human participants have been performed in compliance with the institutional, national, and international guidelines for human welfare and have been reviewed by the local institutional review board.
1. Obtaining Tissue Samples
NOTE: A critical component of this protocol requires proper handling of the tissue donation starting immediately at the time of autopsy. The overall sample viability depends significantly on minimizing the Post-Mortem Interval (PMI), immediately transferring the tissue into the appropriate cold medium supplemented with antibiotics/anti....
