abstract = {Astrocytes are abundant cell types in the vertebrate
central nervous system and can act as neural stem cells in
specialized niches where they constitutively generate new
neurons. Outside the stem cell niches, however, these glial
cells are not neurogenic. Although injuries in the mammalian
central nervous system lead to profound proliferation of
astrocytes, which cluster at the lesion site to form a
gliotic scar, neurogenesis does not take place. Therefore, a
plausible regenerative therapeutic option is to coax the
endogenous reactive astrocytes to a pre-neurogenic
progenitor state and use them as an endogenous reservoir for
repair. However, little is known on the mechanisms that
promote the neural progenitor state after injuries in
humans. Gata3 was previously found to be a mechanism that
zebrafish brain uses to injury-dependent induction of neural
progenitors. However, the effects of GATA3 in human
astrocytes after injury are not known. Therefore, in this
report, we investigated how overexpression of GATA3 in
primary human astrocytes would affect the neurogenic
potential before and after injury in 2D and 3D cultures. We
found that primary human astrocytes are unable to induce
GATA3 after injury. Lentivirus-mediated overexpression of
GATA3 significantly increased the number of GFAP/SOX2 double
positive astrocytes and expression of pro-neural factor
ASCL1, but failed to induce neurogenesis, suggesting that
GATA3 is required for enhancing the neurogenic potential of
primary human astrocytes and is not sufficient to induce
neurogenesis alone.},
