Brain Transplantation of Immortalized Human Neural Stem Cells Promotes Functional Recovery in Mouse Intracerebral Hemorrhage Stroke Model

Abstract

We have generated stable, immortalized cell lines of human NSCs from primary human fetal telencephalon cultures via a retroviral vector encoding v-myc. HB1.F3, one of the human NSC lines, expresses a normal human karyotype of 46, XX, and nestin, a cell type-specific marker for NSCs. F3 has the ability to proliferate continuously and differentiate into cells of neuronal and glial lineage. The HB1.F3 human NSC line was used for cell therapy in a mouse model of intracerebral hemorrhage (ICH) stroke. Experimental ICH was induced in adult mice by intrastriatal administration of bacterial collagenase; 1 week after surgery, the rats were randomly divided into two groups so as to receive intracerebrally either human NSCs labeled with ␤-galactosidase (n ‫؍‬ 31) or phosphate-buffered saline (PBS) (n ‫؍‬ 30).

Improving Effect of Silk Peptides on the Cognitive Function of Rats with Aging Brain Facilitated by D-Galactose

“…For the evaluation of the effects of SP preparations on neuronal ChAT mRNA expression, human neural stem cells encoding ChAT gene (F3.ChAT) was used (Kim, 2004;Matsuo et al, 2005;Lee et al, 2007a). F3.ChAT cells (1×10 6 cells/ ml) were incubated with 10 or 100 μg/ml of SP-NN or SP-PN at 37 o C for 24 hours in a 5% CO 2 incubator.…”

Transplantation of Neural Stem Cells That Overexpress Sod1 Enhances Amelioration of Intracerebral Hemorrhage in Mice

“…5,6,8,38 The present SOD1 enhances stem cell therapy in mouse ICH T Wakai et al study shows that transplantation of SOD1 Tg NSCs in ICH brains reduced their atrophy and death. Moreover, an improvement in the outcome of behavioral tests was observed in these animals, indicating that stem cells facilitate neuroprotection after being grafted to ICH brains.…”

Therapeutic targeting of subdural medulloblastomas using human neural stem cells expressing carboxylesterase

“…[20][21][22] HB1.F3.rCE (F3.rCE) cells were prepared by transduction with replication-deficient retrovirus that harbor the pLPCX vector, which contains the rCE gene. 12 Vectors were packaged by co-transduction of the rCE puromycin plasmid with the MV12 envelope-coding plasmid cDNA into pA317 cells.…”
