objective(s): stem cell therapy is believed to be as a promising treatment strategy for tissue repair and regeneration. the plasticity specification of the adult stem cells, such as mscs, has enabled that these cells to be used in the treatment of a broad spectrum of diseases like liver disorders. in this study, the production of urea and albumin (alb), glycogen storage, and expression of some ...
One-quarter of a century ago, identification of the human retinoblastoma gene (RB) loci proved Knudson's 'two-hit theory' that tumor suppressor genes exist. Since then, numerous works delineated crucial roles for the RB protein (pRB)-E2F transcription factor complex in G1-S phase transition. In addition, discovering the relationship between pRB and tissue-specific transcription factors enabled ...
embryonic stem cells (escs) as pluripotent stem cells have the potential to give rise to all three germ layer cells. also, these cells have the self-renewing ability. escs could differentiate into most of cell lineages. lymphocytes generated from hematopoietic stem cells. we designed a feeder free culture condition to generate lymphoid lineage cells from escs. we demonstrated that il-7 plays cr...
Introduction: One of the vital enzymes during spermatogenesis, which is one of the pluripotency factors of stem cells and contributes to maintaining their pluripotency is alkaline phosphatase. ZBTB16 and ZFP proteins are critical elements in stem cells which are expressed in pluripotent stem cells and maintain their pluripotency due to their role in messaging pathways. Material & Methods: The ...
Here we have reviewed the conventional definitions and fundamental characteristics of the two basic types of stem cells, embryonic stem cells (ESCs) and somatic stem cells (SSCs). By taking into account the often-overlooked asymmetric cell kinetics of SSCs, we consider the evidence that should SSCs retain these growth kinetics in vitro, a natural kinetic barrier to SSC propagation exists. Recen...
Pan-cancer analysis can identify cell- and tissue-specific genomic loci and regions with underlying biological functions. Here we present an online curated DNA Methylation Annotation Knowledgebase, DMAK, which includes the pan-cancer analysis results for differentially-methylated loci and regions by the Reduced Representation Bisulfite Sequencing profiling technology. DMAK contains 3 modules of...
MicroRNAs (miRNAs) are small non-coding RNAs that regulate messenger RNAs at the post-transcriptional level. They play an important role in the control of cell physiological functions, and their alterations have been related to cancer, where they can function as oncogenes or tumor suppressor genes. Recently, they have emerged as key regulators of "stemness", collaborating in the maintenance of ...
