It has been shown that FNC cryopreservation according to developed program provided the high integrity of structural-phenotypic characteristics of FNCs. Neuro- and glioblasts with higher percentage of integrity were more cryoresistant under freezing with 10% DMSO. These data correlated with the expression indices in cells of neurospecific proteins such as: nestin and glial fibrillar acid protein (GFAP) and also one of proteins of neurofilaments, β-tubulin. Whereas nestin is mainly immuno-morphological marker of neural stem/progenitor cells and GFAP is the “marker” protein of glial cells it is supposed that selected cryopreservation protocols may be used as a “natural” sorter, enabling the selection of neuronal stem/progenitor or glial cells.</p> ER -
