The way to overcome current limitations in the generation of glucose-responsive insulin-producing cells is selective enrichment of the number of definitive endoderm (DE) progenitor cells. Sox17 is the marker of mesendoderm and definitive endoderm. The aim of the present research was to study the potential of Sox17 knock-in CGR8 mouse embryonic stem (ES) cells to differentiate into insulin produ...

Prostate cancer (PCa) stem/progenitor cells are known to have higher chemoresistance than non-stem/progenitor cells, but the underlying molecular mechanism remains unclear. We found the expression of testicular nuclear receptor 4 (TR4) is significantly higher in PCa CD133(+) stem/progenitor cells compared with CD133(-) non-stem/progenitor cells. Knockdown of TR4 levels in the established PCa st...

Progenitor Leydig cells are derived from stem cells. The proliferation and differentiation of progenitor Leydig cells significantly contributes to Leydig cell number during puberty. However, the regulation of these processes remains unclear. The objective of the present study was to determine whether luteinizing hormone (LH) or androgen contributes to the proliferation and differentiation of pr...

UHRF proteins catalyze the ubiquitination of target and are involved in regulating gene expression. Some studies reported a reduced expression UHRF2 acute leukemia cells, but role hematopoiesis remains unknown. Here, we generated Uhrf2−/− mice to clarify deletion hematopoiesis. Compared Uhrf2+/+ mice, showed no differences complete blood counts, as well bone marrow (BM) findings spleen weights....

Background: Promyelocytic leukemia protein (PML) is a tumor suppressor protein that is involved in myeloid cell differentiation in response to retinoic acid (RA). In addition, RA acts as a natural morphogen in neural development. Objectives: This study aimed to examine PML gene expression in different stages of in vitro neural differentiation of NT2 cells, and to investigate the possible role o...

It is unclear why aging causes a drop in lymphoid-biased HSC numbers and decline lymphoid progenitor quality. One possibility that stem cells have inherently programmed processes at work, which would imply these an internal clock controls their functionality lifetime. This study aims to summarize current evidence regarding the Effect of on White Blood Cells Count immunity. The PubMed database E...

A growing amount of evidence demonstrates that Endothelial Progenitor Cells (EPCs) are involved in adult neovasculogenesis and maintenance of vascular integrity. EPC decrease and dysfunction are related to atherosclerosis and cardiovascular disease (CVD), and it has been proposed that the level of circulating EPCs may be used as a surrogate index of cumulative cardiovascular risk. Moreover, man...

Angiogenesis and neurogenesis are coupled processes. Using a coculture system, we tested the hypothesis that cerebral endothelial cells activated by ischemia enhance neural progenitor cell proliferation and differentiation, while neural progenitor cells isolated from the ischemic subventricular zone promote angiogenesis. Coculture of neural progenitor cells isolated from the subventricular zone...
