Functional Neuronal Cells Generated by Human Parthenogenetic Stem Cells
Parent of origin imprints on the genome have been implicated in the regulation of neural cell type differentiation. The ability of human parthenogenetic (PG) embryonic stem cells (hpESCs) to undergo neural lineage and cell type-specific differentiation is undefined. We determined the potential of hpESCs to differentiate into various neural subtypes. Concurrently, we examined DNA methylation and...
متن کاملNonhuman primate parthenogenetic stem cells.
Parthenogenesis is the biological phenomenon by which embryonic development is initiated without male contribution. Whereas parthenogenesis is a common mode of reproduction in lower organisms, the mammalian parthenote fails to produce a successful pregnancy. We herein describe in vitro parthenogenetic development of monkey (Macaca fascicularis) eggs to the blastocyst stage, and their use to cre...
متن کاملInducing human parthenogenetic embryonic stem cells into islet-like clusters
In order to determine whether human parthenogenetic embryonic stem (hpES) cells have the potential to differentiate into functional cells, a modified four‑step protocol was used to induce the hpES cells into islet‑like clusters (ILCs) in vitro. Growth factors activin A, retinoic acid, nicotinamide, Exendin‑4 and betacellulin were added sequentially to the hpES cells at each step. The terminally...
متن کاملTransdifferentiation of Human Dental Pulp Stem Cells Into Oligoprogenitor Cells
Introduction: The nerve fibers in central nervous system are surrounded by myelin sheet which is formed by oligodendrocytes. Cell therapy based on oligodendrocytes and their precursors transplantation can hold a promising alternative treatment for myelin sheet repair in demyelinating diseases. Methods: Human Dental Pulp Stem Cells (hDPSCs) are noninvasive, autologous and easy available s...
متن کاملParthenogenetic Activation of Porcine Oocytes and Isolation of Embryonic Stem Cells-like Derived from Parthenogenetic Blastocysts
These experiments were carried out to optimize the parameters of electrical activation, methods of parthenogenetic activation and embryo culture in vitro and meanwhile to isolate embryonic stem cells-like (ESCs) derived from porcine parthenogenetic blastocysts (pPBs). These results showed that, as the electric field strength increased from 1.0 to 2.7 kV/cm, the cleavage rate of parthenogenetic ...
