The role of glial cells missing 2 in induced pluripotent stem cell parathyroid differentiation
Glial cells missing 2 (GCM2) has been identified as an essential factor for parathyroid differentiation, and GCM2 silencing in parathyroid cells decreases calcium-sensing receptor (CaSR) expression. However, the role of GCM2 in parathyroid differentiation from induced pluripotent stem cells (iPSCs) is unclear. Here, we investigated the role of GCM2 in parathyroid differentiation from iPSCs using the Tet-On 3 G system. We confirmed that iPS cells transfected with GCM2/TRE3G and pCMV-Tet3G vectors express GCM2 in a doxycycline-dependent manner. Though parathyroid glands derive from the endoderm and differentiate via the third pharyngeal arch (PPE), overexpression of GCM2 in iPSCs significantly abolished the suppression of OCT4 and SOX2, suggesting inhibition of endodermal differentiation. GCM2 overexpression at the stage of differentiation into the third PPE also increased the expression levels of CaSR and parathyroid hormone, and increased the number of CaSR+/EpCAM+ cells. These results suggest that GCM2 regulates parathyroid differentiation after endoderm differentiation rather than at an earlier stage.
期刊介绍：
Tissue and Cell is devoted to original research on the organization of cells, subcellular and extracellular components at all levels, including the grouping and interrelations of cells in tissues and organs. The journal encourages submission of ultrastructural studies that provide novel insights into structure, function and physiology of cells and tissues, in health and disease. Bioengineering and stem cells studies focused on the description of morphological and/or histological data are also welcomed.
Studies investigating the effect of compounds and/or substances on structure of cells and tissues are generally outside the scope of this journal. For consideration, studies should contain a clear rationale on the use of (a) given substance(s), have a compelling morphological and structural focus and present novel incremental findings from previous literature.
