Not exact matches

Embryonic stem cells are scientifically and medically interesting because they are «pluripotent» (capable of generating many cell types), but they are not the same as totipotent single - cell embryos.

Thus, unlike totipotent single - cell embryos, pluripotent embryonic stem cells are specialized cells that have limited developmental capabilities.

Such a single - step conversion of an adult cell into an embryonic stem cell entirely avoids the question of whether an embryo has been created, since the cell produced by ANT - OAR never exhibits any of the properties of a single - cell embryo.

In 2009, from experiments at the RIKEN Center for Developmental Biology in Kobe, Japan, he found that when culture conditions are right, adding a single ingredient — bone morphogenetic protein 4 (Bmp4)-- with precise timing is enough to convert embryonic cells to PGCs.

The results help fill in the scientific puzzle kicked off by Dolly's cloning, which proved that mammalian egg cells were capable of dissolving the genetic roadblocks that limit the potential of most adult cells to give rise to only a single type of tissue — that of the organ from which they hail — whereas embryonic stem cells have the potential to become virtually any kind of body tissue.

I believe the culture of embryonic stem cells represents the single most important contribution to biology over the last 25 years.

The other is to take a single facet and just make it bigger and then add more light sensitive cells down below during embryonic development.

The authors illustrate the power of their approach using 20 distinct biological systems ranging from single - molecule binding kinetics to cell migration and division, immunology, and embryonic development.

In their initial experiments, Hwang and his colleagues used cells from a single donor to try to create embryonic clones; they transferred nuclei from ovarian cells back into the donors» own oocytes.

\ n \ nWhile historically there had been a ban on taxpayer funding of embryonic stem cell research, there has never been a ban on private funding in this country and many European countries have allowed this type of research for years, but so far none of this research has yielded a single therapeutic use.

The Mouse Molecular Technologies team provide high - throughput genotyping and characterisation of mutant mouse strains created either by targeted embryonic stem cells (ESC) or CRISPR / Cas9 gene editing in single - cell zygotes.

His recent published work describes the rescued visual function in animals using retinal pigment epithelial cells derived from human embryonic stem cells and a method for deriving stem cells using a single - cell approach that does not harm embryos.

Human pluripotent stem cells (hPSCs), including human embryonic stem cells (hESCs) and human induced pluripotent stem cells (hiPSCs), are known to be vulnerable to apoptosis upon various technical manipulation, such as single cell dissociation, freezing and thawing, etc., which hinder their use for clonal isolation in gene transfer, differentiation and FACS cell sorting.

It took 242 eggs to get a single culture of embryonic stem cells to grow.

The use of human embryonic stem cells, as opposed to patient blood, as the starting material for AST - VAC2 provides a scalable system for the production of a large number of vaccine doses in a single lot, reducing manufacturing costs, enabling «off - the - shelf» availability, and ensuring product consistency.

What she has shown is you can make mouse embryonic stem cells convert unidirectionally to trophoblasts by activating a single gene.

He realized that a single cell might have a shot if it shared its lab dish with some special roommates — some other cells that already know how to be embryonic stem cells.

Dr Harris normally took a libertarian stand on bioethical issues and was a forceful and reliable supporter of human embryonic stem cell research, abortion, euthanasia, anonymous sperm donation, IVF for lesbians and single parents and so on.

Additionally, single - cell derived bovine iPSCs formed embryoid bodies and teratomas that all subsequently gave rise to differentiated cells from all three embryonic germ layers.

These findings on gene expression in single embryonic stem cells are in concert with recent studies of early mammalian development, which reveal molecular heterogeneity and a stochasticity of gene expression in blastomeres.

The researchers suggest that a single expandable embryonic lung progenitor population with broader developmental competence may eventually be used as an alternative for region - restricted adult tissue stem cells in regenerative medicine.

Thus, the ability to measure DNAme in single cells has the potential to make important contributions to the understanding of several key biological processes, such as embryonic development, disease progression and aging.

In the November 6 Nature Methods, the team led by Bing Lim and Massimo Nichane of the Genome Institute of Singapore and Kyle M. Loh of Stanford University School of Medicine, and including Siva V, Ph.D., of The Jackson Laboratory's Single Cell Biology Lab, showed that mouse Sox9 + multipotent embryonic lung progenitors can be isolated and expanded long - term in 3D culture.

His current research interests include developing morphologic and biologic markers of embryo viability in order to enable single embryo transfer and avoid multiple pregnancies; optimizing preimplantation genetic testing; and deriving human embryonic stem cell lines.
