Regenerative capacity of mammals is limited and can rarely regenerate a specific organ or tissue fully. Due to these limitations, regenerative medicine seeks efficient and safe cell sources for regeneration of damaged tissues and organs or treatment for incurable diseases. Human embryonic stem cells (HESCs) hold two important properties called self renewal and pluripotency. However, the use of ...
Induced pluripotent stem cells (iPSCs) generated by ectopic expression of four transcription factors have great promises for regenerative medicine in humans. Since the initial report of iPSCs by viral transfection, ample efforts have been made in the generation of iPSCs through nonviral approaches. Small molecules offer the advantages of low cost without genomic modification and have been used ...
Introduction: During the last decade, advances in tissue engineering and stem cell-based tooth regeneration have provided realistic and attractive means of replacing lost or damaged teeth. The first adult stem cells isolated from dental tissues were dental pulp stem cells (DPSCs). When transplanted with hydroxyl apatite/tri calcium phosphate (HA/TCP) powder, they formed a dentin-like structure...

Research and experimentation on embryonic stem cells has opened new horizons in different fields of medical science. The particular characteristic of these cells in its ability to produce different body cells has raised the hopes for treating a wide range of diseases and repairing damaged tissues. Alongside the progress in research and technology, a variety of legal challenges have also been po...
BACKGROUND Existing dogma that a female is born with fixed number of eggs was challenged by the detection of stem cells in adult mammalian ovary. Data has accumulated in support of ovarian stem cells (OSCs) proliferation, maintenance in culture, formation of germ cell nests and differentiation into oocytes and primordial follicle assembly using different strategies. RESULTS Flow cytometry ana...
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...
background: the transcription factor oct-4, is an important marker of undifferentiating level and a key regulating factor for maintenance of pluripotency in cells. establishment of an oct-4 promoter-based reporter system is an appropriate tool for monitoring the differentiation of embryonic stem cells both in vivo and in vitro. methods: in the present study, we report construction of a recombin...
Pluripotent stem cells have the potential to differentiate into 200 odd cell types present in adult body. Pluripotent stem cells available for regenerative medicine include embryonic stem (ES) cells, induced pluripotent stem (iPS) cells and very small ES-like stem (VSELs) cells. Nuclear OCT-4 is one of the crucial factors that dictate pluripotent state. Compared to ES/iPS cells grown in Petri d...
