siRNA-mediated gene knockdown in rat neural stem cells (NSCs) presents unique challenges due to the complexity of the blood-brain barrier (BBB), the fragile nature of NSCs, and the need for precise targeting of specific genes within the central nervous system (CNS). Successful delivery of siRNA to NSCs in vivo generally requires advanced methods to bypass…
Electroporation is a powerful physical method for enhancing the intracellular delivery of nucleic acids, particularly in tissues such as skeletal muscle, where direct injection of naked DNA often results in poor uptake. In vivo electroporation in rats requires careful control of multiple parameters, including electrode configuration, applied voltage, pulse duration, and the number of pulses….
Lipid-based transfection remains one of the most widely used non-viral techniques for delivering nucleic acids into primary cells, including rat hepatocytes. Optimizing this method for primary liver cells is critical due to the inherently low transfection efficiency and high sensitivity of hepatocytes to cytotoxic reagents. Key parameters influencing success include the lipid-to-DNA or lipid-to-RNA ratio,…
