The dCas9 fusion plasmids contain a human codon optimized dcas9 gene that is fused to different effector domains, under the control of either a spleen focus-forming virus (SFFV) or a murine Stem cell retrovirus LTR promoter.
This vector has a Murine Stem Cell Virus (MSCV) backbone combined with packaging extract for mammalian cell infection, a PGK- Puro selection for transfection stability in mammalian cells and a chloramphenicol/kanamycin bacterial selection marker.
Human NPM-ALK cDNA was cloned into the Murine Stem Cell Virus (MSCV) puro vector.
The expression of TLX1 in these cells is controlled by the murine stem cell virus derived LTR repeats.
After sequence confirmation, fragments were recloned to murine stem cell virus (MSCV -based MSCV -basedor for retroviral expression.
Most importantly, alpha-6 integrin, the one gene that was found be enriched in all three murine stem cell studies, is similar to alpha-4 integrin that was found to be enriched in our human dataset.
A murine stem cell virus vector containing the BCR-Abelson fusion gene and GFP was transfected with helper virus plasmid into HEK 293T cells, and supernatant was harvested after 36 hours.
The murine stem cell virus (MSCV) promoter drives strong, stable gene expression in hematopoietic stem cells and several other cells, including cerebellar Purkinje cells, but it has not been studied in muscle.
An 800-bp genomic sequence including either wild type PCMT or its antisense counterpart was cloned upstream from the IRES of the MSCV-IRES-GFP (MIGR) (murine stem cell virus-internal ribosome entry site-green fluorescent protein) retrovirus.
The 1MOG9, 1 MOG244.2 [25], 3A9 [32], and PA19.5E11 [33], TCR α and β chains were isolated by PCR and cloned into the MSCV-I-GFP murine stem cell virus-based retroviral vector as described [25].
To promote primary differentiation into EBs, ES cells were cultured in ES differentiation medium containing Iscove's modified Dulbecco's medium (IMDM), 15% FCS (StemCell Technologies), 2 mM glutamine, 150 µM MTG, and 40 ng/ml murine stem cell factor (mSCF).
