Nor do only the cells of the inner cell mass of the blastocyst become the later adult and none of the cells from the inner cell mass become part of the placenta, umbilical cord, etc. (lifeissues.net)

One man ended up with teeth and hair in is brain and died from an embryonic stem cells implant. (prolifeaction.org)
those with more comprehensive damage may need a cochlear implant to compensate for the hair cell deficit. (scienceabode.com)
In these patients it is possible that stem cells should be administered in combination with a cochlear implant. (scienceabode.com)

In the longer term, we'd like to produce controlled heterogeneous embryonic bodies" concludes Rui Yao. (phys.org)
The group also reported their cells are heterogeneous, a ?mixed population? (lifecoderx.com)

Researchers have developed a new technique for creating human embryonic stem cells by fusing adult somatic cells with embryonic stem cells. (news-medical.net)
In theory, researchers can induce embryonic stem cells to mature into a variety of specialized cells. (news-medical.net)
For that reason, many researchers believe stem cells offer promise for creating populations of specialized cells that can be used to rejuvenate organs, such as the pancreas or heart, that are damaged by disease or trauma. (news-medical.net)
Eggan, Melton and their colleagues decided to pursue their alternative route after other researchers had shown that genetic reprogramming can occur when mouse somatic cells are fused to mouse embryonic stem cells. (news-medical.net)
The researchers demonstrated that they had achieved fusion of the two cell types by searching the fused cells for two distinctive genetic markers present in the somatic fibroblast and stem cells. (news-medical.net)
The researchers were also able to further confirmed that fusion occurred by studying the chromosomal makeup of the fused cells. (news-medical.net)
The researchers also performed fusion experiments using pelvic bone cells as the somatic cells and a different human embryonic cell line, to demonstrate that their technique was not restricted to one adult cell type or embryonic cell line. (news-medical.net)
Researchers identified that an abundance of fungi in the gut, particularly strains of Candida albicans yeast, could trigger an increase in immune cells, which could worsen lung damage. (medicaldaily.com)
Researchers are learning how to create many different specialised cell types found in the body by exposing ESCs to different signalling molecules and growth conditions. (eurostemcell.org)
Researchers have devised a novel biosensor that can isolate and target leukemic stem cells. (longdom.com)
In a new study, researchers have learned how a specific genetic mutation affects the maturation of blood cells in mouse models. (longdom.com)

This approach could become an alternative to somatic cell nuclear transfer (SCNT), a method that is currently used to produce human stem cells. (news-medical.net)
Their analyses showed that the hybrid cells were "tetraploid" - meaning they contained the combined chromosomes of both the somatic cells and the embryonic stem cells. (news-medical.net)
The long term goal for this experiment was to do cell fusion in a way that would allow the elimination of the embryonic stem cell nucleus to create an embryonic stem cell from the somatic cell," said Melton. (news-medical.net)
Clusters of neurons in the somatic peripheral nervous system which contain the cell bodies of sensory nerve axons. (lookformedical.com)

The inner ear contains sensory epithelia composed of mechanosensitive hair cells, supporting cells, and sensory neurons that work in concert to detect sound and positional information and transmit those signals to the brain. (springer.com)
found in cells of basal stratum of stratified epithelia. (edu.au)
A research team led by Eri Hashino, Ph.D., Ruth C. Holton Professor of Otolaryngology at Indiana University School of Medicine, reported that by using a three-dimensional cell culture method, they were able to coax stem cells to develop into inner-ear sensory epithelia - containing hair cells, supporting cells and neurons - that detect sound, head movements and gravity. (iu.edu)

This would promote different cell types developing next to each other - which would lead the way for growing micro-organs from scratch within the lab. (phys.org)
Mouse ESCs are being used to learn about how the body develops, from early embryonic stages to the formation of complex organs. (eurostemcell.org)

Baker C, Bronner-Fraser M (2001) Vertebrate cranial placodes I. Embryonic induction. (springer.com)
The group said adult skin-derived precursors have been found in the past to be ?highly potent in hair induction, but progressive loss? (lifecoderx.com)

These multipotent stem cells contain certain proteins - called markers - that have previously been found only in embryonic stem cells. (loe.org)
I think that we've produced a 3-D microenvironment which much more like that found in vivo for growing embryoid body, which explains the higher levels of cell proliferation. (phys.org)
We found five derivatives that significantly protect hair cells against NIHL. (creighton.edu)
Biologists have found that aging takes a toll on intestinal stem cells and may contribute to increased susceptibility to disorders of the gastrointestinal tract. (longdom.com)
They also found that these cells had defective mitochondria, a specialized cellular structure that uses oxygen to generate energy for fueling cellular metabolism. (bbrfoundation.org)

Srf-null embryonic airway smooth muscle exhibits a synthetic phenotype, compared with the contractile phenotype of mature wild-type airway smooth muscle. (bvsalud.org)

Most cells are specialised to perform particular functions, such as red blood cells that carry oxygen around our bodies in the blood, but they are unable to divide. (yourgenome.org)
therapy - to replace lost or damaged cells that our bodies can't replace naturally. (yourgenome.org)

As well as proving that stem cells can be used to repair damaged hearing, it is hoped the breakthrough - published in the journal Nature - will lead to new treatments and therapies in the future. (scienceabode.com)

Competing research groups have already provided conceptual evidence in an animal model system and have demonstrated that an embryonic tooth implanted into the jaw actually develops into a complete tooth. (bionity.com)

Within the utricle and saccule, the sensory cells are arranged in a flat plate of cells called a macula. (cdc.gov)
