Optimising CRISPR gene editing of hard-to-transfect cells

Posted by in categories: bioengineering, biotech/medical

CRISPR has transformed gene editing, but still presents challenges in hard-to-transfect cells, such as pluripotent stem cells and primary cells.1 The key to obtaining successful transfection in these cells lies in innovative workflows. Here Georges Müller, CEO and cofounder of SEED Biosciences, shares his perspective on why focusing on editing a single cell, rather than bulk cells, is a pivotal strategy to optimise CRISPR delivery.

Delivery of ribonucleoprotein (RNP) into cells is an essential factor for successful CRISPR gene editing. However, this is difficult to guarantee using traditional CRISPR gene editing methods, especially in hard-to-transfect cells. The standard CRISPR technique involves gathering a group of cells and then electroporating them, using short high-voltage pulses to overcome the barrier of their cell membranes. This allows bulk transfection of ribonucleoprotein (RNP) into the cells and then hopefully, nuclear translocation.
