Background and Aim: Embryonic stem cells are identified with two unique characteristics. First, they can be maintained and expanded as pure populations of undifferentiated cells, a characteristic which is known as self renewal aspect of embryonic stem cells. Second, these cells can give rise to all body cell types. In the current study, we used a feeder-free condition to differentiate mouse emb...
Due to the extremely limited proliferative capacity of adult cardiomyocytes, human embryonic (pluripotent) stem cell derived cardiomyocytes (hESC-CMs) are currently almost the only reliable source of human heart cells which are suited to large-scale production. These cells have the potential for wide-scale application in drug discovery, heart disease research and cell-based heart repair. Embryo...
In many arthropods, the appearance of new segments and their differentiation are not completed by end embryogenesis but continue, in different form degree, well after hatching, some cases up to last post-embryonic molt. Focusing on segmentation process currently described as segment addition (or, anamorphosis), we revise here current knowledge discuss it an evolutionary framework which involves...
Stem cells are classified into embryonic stem cells and adult stem cells. An evolving alternative to conventional stem cell therapies is induced pluripotent stem cells (iPSCs), which have a multi-lineage potential comparable to conventionally acquired embryonic stem cells with the additional benefits of being less immunoreactive and avoiding many of the ethical concerns raised with the use of e...
Screening cocktails of candidate genes for induction of pluripotency and self-renewal in nonstem cells has identified a surprising new embryonic stem cell regulator, the myc proto-oncogene. Here the possible mechanisms by which myc controls self-renewal and pluripotency are discussed.
Human embryonic stem cells are pluripotent entities, theoretically capable of generating a whole-body spectrum of distinct cell types. However, differentiation of these cells has been observed only in culture or during teratoma formation. Our results show that human embryonic stem cells implanted in the brain ventricles of embryonic mice can differentiate into functional neural lineages and gen...
