Abstract

Oligodendrocytes play critical roles in the central nervous system (CNS) thorough producing myelin sheaths around axons. There are a variety of approaches to produce oligodendrocytes in vitro and in vivo which are a subject of interest in many studies. A new approach to induce this differentiation is using microRNA 219 (miR-219). However, this new approach suffers from a lack of studies regarding the effect of miR-219 on differentiating human induced pluripotent stem cells (hiPSCs) to oligodendrocytes. This study aimed to assess the impact of miR-219-overexpression on hiPSCs. Initially, hiPSCs were induced with basic fibroblast growth factor (bFGF), epidermalgrowth factor (EGF) and platelet-derived growth factor (PDGF)-AA, then, miR-219- green fluorescent protein (GFP)-expressing lentiviruses were utilized for cell infection. Microscopic observation revealed significant morphological changes and data obtained from quantitative reverse transcription PCR and immunofluorescence analysis of differentiated cells showed that the expression of various oligodendrocyte stage-specific markers such as Nestin, Olig2, Sox10, PDGFRα, A2B5, O4, and MBP increased. In addition, higher expressions of pre-oligodendrocyte markers were detected in the cells transduced with miR-219 lentivirus in comparison with the cells treated with triiodothyronine (T3). These results suggest that overexpression of miR-219 promotes differentiation of hiPSCs to pre-oligodendrocyte cells, providing a potential source for cell therapy by replacing and restoring the lost cell function in neurodegenerative and demyelinating diseases.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
