Sentences with word «blastomere»

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.

More than half of the 91 blastomeres divided at least once, and 28 formed clumps that grew in culture.

Researchers could allow the removed blastomere to grow overnight, giving it time to divide.

The ACT scientists allowed the embryos to develop to the morula stage, when the embryo contains 8 to 16 cells, also called blastomeres.

Comparison of epigenetic mediator expression and function in mouse and human embryonic blastomeres.

In Xenopus, Noggin can direct the progeny of early blastomeres, not normally destined to contribute to the eyes, to a retinal fate [19], [20].

Cells are only transiently pluripotent as cell fate specification signals initiate differentiation soon after the formation of pluripotent blastomeres.

Surface tensions γcm from contacting blastomeres can then be used to calculate the tension along cell - cell contacts γcc by taking into account the contact angles θ.

The unpolarised blastomere on top shows prominent periodic cortical of contraction while the polarised sister cell on the bottom remains quiet.

The polarised blastomere will later envelop its unpolarised sister cell, which will become embryonic tissue.

They used a pipette to separate the blastomeres and then cultured each one separately to see if it would grow into an ES cell line.

We previously demonstrated that hESCs can be generated from single blastomeres (Klimanskaya -LSB-...]

From our experience with Preimplantation Genetic Diagnosis (PGD) we saw that a low mutation load at the blastomere stage reflects the mutation load in the child when it is born.

The collection of protocols includes the isolation and maintenance of stem cells from various species using «conventional» and novel methods, such as derivation of ES cells from single blastomeres, differentiation of stem cells into specific tissue types, isolation and maintenance of somatic stem cells, stem cell - specific techniques and approaches to tissue engineering using stem cell derivatives.

Surface tensions γcm are measured for all blastomeres sequentially by finding the critical pressure Pc giving a deformation of the size of the micropipette Rp and measuring the radius of curvature of the cell Rc.

16 - cell stage doublet resulting from the asymmetric division of an isolated 8 - cell stage blastomere.

Likewise, the expression pattern of cdx - 2, a key transcription factor in the trophoblast lineage, overlaps with that of Oct - 4, but within any blastomere, cdx - 2 expression bears no consistent relationship to that of Oct - 4 or nanog until after the trophectoderm lineage has been sorted [9].
