title: The differentiation and engraftment potential of mouse hematopoietic stem cells is maintained after bio-electrospray.
abstract: The bio-electrospray technique has been recently pioneered to manipulate living, immortalised and primary cells, including a wide range of stem cells. Studies have demonstrated that the creation of viable, fully functional in vitro microenvironments is possible using this technique. By modifying the bio-electrospray procedure (referred to as cell electrospinning), a variety of microenvironment morphologies have been fabricated. Because bio-electrospraying of biological material is a relatively new technique, it is important to determine if there are any unwanted consequences to the manipulated cells as a result of the procedure. Here, we establish the validity of the process using a heterogeneous, living population of hematopoietic stem/progenitor cells, using a functional in vitro assay and in vivo mouse model to investigate for side-effects that previous in vitro assays may not have detected. Our studies demonstrate that these bio-protocols have no obvious negative effects, thus indicating significant promise for utility in biological sciences and for a plethora of healthcare applications.
