“…This technique completely eliminates genome manipulation and the DNA integration that may cause mutations and activation of proto-oncogenes expression, leading to possible malignancy and other undesired results. Several gene therapy applications prefer the use of mRNA instead of plasmid DNA and viral vectors in the face of its requirement for stable transgene expression [ 57 ]. mRNA reprogramming also surpasses obstacles in the protein delivery method including cost and time.…”

Reprogramming of somatic cells has great potential to provide therapeutic treatments for a number of diseases as well as provide insight into mechanisms underlying early embryonic development. Improvement of induced Pluripotent Stem Cells (iPSCs) generation through mRNA-based methods is currently an area of intense research. This approach provides a number of advantages over previously used methods such as DNA integration and insertional mutagenesis. Using transfection of specifically synthesized mRNAs of various pluripotency factors, we generated iPSCs from mouse embryonic fibroblast (MEF) cells. The genetic, epigenetic and functional properties of the iPSCs were evaluated at different times during the reprogramming process. We successfully introduced synthesized mRNAs, which localized correctly inside the cells and exhibited efficient and stable translation into proteins. Our work demonstrated a robust up-regulation and a gradual promoter de-methylation of the pluripotency markers, including non-transfected factors such as Nanog, SSEA-1 (stage-specific embryonic antigen 1) and Rex-1 (ZFP-42, zinc finger protein 42). Using embryonic stem cells (ESCs) conditions to culture the iPS cells resulted in formation of ES-like colonies after approximately 12 days with only five daily repeated transfections. The colonies were positive for alkaline phosphatase and pluripotency-specific markers associated with ESCs. This study revealed the ability of pluripotency induction and generation of mouse mRNA induced pluripotent stem cells (mRNA iPSCs) using transfection of specifically synthesized mRNAs of various pluripotency factors into mouse embryonic fibroblast (MEF) cells. These generated iPSCs exhibited molecular and functional properties similar to ESCs, which indicate that this method is an efficient and viable alternative to ESCs and can be used for further biological, developmental and therapeutic investigations.

Recombinant adeno-associated virus 2 (AAV) vectors have taken center stage owing to their potentially safer profile compared with the more commonly used retroviral and adenoviral vectors in human gene therapy clinical trials. Their remarkable versatility and efficacy in a wide variety of preclinical animal models of human diseases have attracted further attention of a number of investigators. Although two particular cell types, muscle and brain, have been shown to be highly transducible by AAV vectors, controversies abound with reference to the efficacy of these vectors in transducing primary hematopoietic cells. Whereas some investigators have claimed that primitive hematopoietic cells are impervious to AAV vectors, others have reported that AAV vectors are capable of transducing these cells, but only at high vector-to-cell ratios. Still other investigators have reported successful transduction of primitive hematopoietic cells at relatively low vector-to-cell ratios. This review attempts to resolve these controversies, and provides a basis for the optimism that safe and high-efficiency transduction of hematopoietic stem and progenitor cells by AAV vectors is well within reach.
