Abstract:
:Short-term and long-term (greater than 7 months) cultured astrocytes from 14-day-old rat brain were analyzed for ganglioside content. Analysis of the extracted gangliosides by HPTLC revealed that ganglioside GM1 was absent in 35 days and 235 days cultured astrocytes, and that the predominant ganglioside was GM3, showing a double band in both cases. A small amount of the disialogangliosides (GD3, GD1a) was also detected. More than 70% of radioactivities into ganglioside fractions by cultured astrocytes, in the presence of N-[3H]-acetylmannosamine, appeared in ganglioside GM3. The upper band component of GM3 increased 60% in long-term astrocyte cultures compared to 35-day-old cultures. Also, an increased GD3 content in long-term astrocyte cultures was detected. These results suggest that the increase of GD3 and upper band GM3 in long-term cultured astrocytes might be related to the appearance of small processes showing strong reactivity against GFAP and vimentin during astrocyte-subculture.
