Extract of mouse embryonic stem cells induces the expression of pluripotency genes in human adipose tissue-derived stem cells
Objective(s): In some previous studies, the extract of embryonic carcinoma cells (ECCs) and embryonic stem cells (ESCs) have been used to reprogram somatic cells to more dedifferentiated state. The aim of this study was to investigate the effect of mouse ESCs extract on the expression of some pluripotency markers in human adipose tissue-derived stem cells (ADSCs). Materials and Methods: Human A...
متن کاملReprogramming by cytosolic extract of human embryonic stem cells improves dopaminergic differentiation potential of human adipose tissue-derived stem cells
The extract of pluripotent stem cells induces dedifferentiation of somatic cells with restricted plasticity. In this study, we used the extract of human embryonic stem cells (hESC) to dedifferentiate adipose tissue-derived stem cells (ADSCs) and examined the impact of this reprogramming event on dopaminergic differentiation of the cells. For this purpose, cytoplasmic extract of ESCs was prepare...
متن کاملI-54: New Models for Human and Mouse Genetic
The possibility to reprogram somatic human cells will greatly and deeply change genetic approach and allow the development of new tools to study genetics diseases. Indeed, our ability to study human genetic diseases suffers from the lack of valid in vitro models. The latter should (i) be originating from human primary cells, (ii) be able to self-renew for a long time and (iii) be able to differ...
متن کاملI-8: Somatic Cell Nuclear Reprogramming byMouse Oocytes Endures Beyond ReproductiveDecline
Background: The mammalian oocyte has the unique feature of supporting fertilization and normal development while being able of reprogramming the nuclei of somatic cells towards pluripotency, and occasionally even totipotency. Whilst oocyte quality is known to decay with somatic ageing, it is not a given that different biological functions decay concurrently. In this study, we tested whether ooc...
متن کاملمطالعه تاثیر بیش بیان ژن OCT4 و مهار همزمان ژن P53 بر بیان ژنهای پرتوانی در سلولهای بنیادی بافت چربی انسان
Background and Objective: OCT4 is the most important transcription factor for reprogramming of somatic cells and maintenance of pluripotency. Moreover, it has recently been shown that loss of P53 or its mutations improve the efficiency of reprogramming. This study was designed to reprogram human adipose tissue-derived stem cells (ADSCs) by overexpression of OCT4 and inhibition of P53 expression...
