Fibronectin fragment CH-296 inhibits apoptosis and enhances ex vivo gene transfer by murine retrovirus and human lentivirus vectors independent of viral tropism in nonhuman primate CD34(+) cells
Re. Donahue et al., Fibronectin fragment CH-296 inhibits apoptosis and enhances ex vivo gene transfer by murine retrovirus and human lentivirus vectors independent of viral tropism in nonhuman primate CD34(+) cells, MOL THER, 3(3), 2001, pp. 359-367
The fibronectin fragment CH-296 improved gene transfer to cytokine-mobilize
d nonhuman primate CD34(+) cells irrespective of tropism to the MoMLV, GaLV
, and VSV-C envelope proteins using murine stem cell virus (MSCV) and human
immunodeficiency virus-1 (HIV-1)-based retrovirus vectors. For the HIV-1 l
entivirus vector, CH-296 enhanced gene transfer in the absence of added hem
atopoietic growth factors necessary for ex vivo stem cell expansion. In the
presence of CH-296, apoptosis of CD34+ cells was inhibited, and in mobiliz
ed peripheral blood CD34+ cells, cell division was stimulated as measured b
y cell history/tracking experiments.
