The preservation of "stemness" in mouse embryonic stem (mES) cells is maintained through a signal transduction pathway that requires the gp130 receptor, the interleukin-6 (IL-6) family of cytokines, and the Janus Kinase-signal transducer and activator (JAK/STAT) pathway.

|
Human ES cells differentiate in the presence of members of the IL-6 family of cytokines including leukemia inhibitory factor (LIF) and IL-6 or in the presence of the designer cytokine hyper-IL-6, which is a complex of soluble interleukin-6 receptor (IL-6R) and IL-6 with greatly enhanced bioactivity.

Human ES cells express LIF, IL-6, and gp130 receptors, as well as the downstream signaling molecules.

Stimulation of human and mouse ES cells with gp130 cytokines resulted in a robust phosphorylation of downstream ERK1, ERK2, and Akt kinases, as well as the STAT3 transcription factor.

MafA promotes the reprogramming of placenta-derived multipotent stem cells into pancreatic islets-like and insulin+ cells.
|
14 |
20158571
|
MafA is a pancreatic transcriptional factor that controls β-cell-specific transcription of the insulin gene.
|
15 |
20158571
|
In this study, we investigate the role of MafA in placenta-derived multipotent stem cells (PDMSCs) that constitutively expressed Oct-4 and Nanog.

|
Our results showed that overexpression of MafA in PDMSCs significantly up-regulated the expression of pancreatic development-related genes (Sox17, Foxa2, Pdx1 and Ngn3).
|
17 |
20158571
|
MafA increased the expression levels of the mRNAs of NKx2.2, Glut2, insulin, glucagons and somatostatin, and further facilitated the differentiation of PDMSCs into insulin(+) cells.
|
18 |
20158571
|
The glucose-stimulated responses to insulin and c-peptide production in MafA-overexpressing PDMSCs were significantly higher than in PDMSCs with vector control.
|
19 |

|
Importantly, the expression of MafA in PDMSCs xenotransplanted into immunocompromised mice improved the restoration of blood insulin levels to control values and greatly prolonged the survival of graft cells in immunocompromised mice with STZ-induced diabetes.
|
20 |

|
In summary, these data suggest that MafA plays a novel role in the reprogramming of stem cells into pancreatic β-progenitors, promotes the islet-like characteristics of PDMSCs, as well as functionally enhances insulin production to restore the regulation of blood glucose levels in transplanted grafts.

The bone marrow (BM) niche contains small heterogenous populations of cells which may contribute to cardiac and endothelial repair, including committed lineages [endothelial progenitor cells (EPCs), multipotent mesenchymal stromal cells (MSCs) and more primitive very small embryonic-like cells (VSELs) expressing pluripotent stem cell (PSC) markers (Oct-4, Nanog, SSEA-1)].

25 |
20981396
|
The isolation of human VSELs is based on their size and presence of several surface markers (CXCR4, CD133, CD34) and lack of markers of hematopoietic lineage (lin, CD45).

|
In acute myocardial infarction and ischemic stroke VSELs are rapidly mobilized into peripheral blood, and express increased levels of PSC markers as well as early cardiac (GATA-4, Nkx2.5/Csx), neural (GFAP, nestin, beta-III-tubulin, Olig1, Olig2, Sox2, Musashi) and endothelial lineage markers (VE-cadherin, von Willebrand factor).
