Since homeoproteins behave as cell-penetrating molecules inside a passive and reversible internalizing process thus rendering genetic manipulations dispensable [32], we developed a cell tradition system based on the active secretion of HOXB4 protein by an engineered MS-5 mouse … Continue reading Since homeoproteins behave as cell-penetrating molecules inside a passive and reversible internalizing process thus rendering genetic manipulations dispensable [32], we developed a cell tradition system based on the active secretion of HOXB4 protein by an engineered MS-5 mouse stromal cell collection, the MS-5/SP-HOXB4 cells (SP: transmission peptide)
