Stem cell lines grown in the lab provide scientists with the opportunity to «engineer» them for use in transplantation or treatment of diseases.

Not exact matches

As well as allowing the use of stem cells grown from established cell lines, the technology could enable the creation of improved human tissue models for drug testing and potentially even purpose - built replacement organs.

In addition, where cells derived from embryonic stem cells are great at proliferating — a potentially critical feature if one wants to grow sufficient numbers of cells for clinical use — ones from the iPS lines were much feebler.

Finally, the team grew the tissue in a three - dimensional system, which coaxed it into forming all the structures found in gut tissue, including the finger - like villi that protrude inwards to increase surface area, and recesses called crypts containing the intestinal stem cells that renew the gut lining weekly (Nature, DOI: 10.1038 / nature09691).

Part of the trouble is the ingredients: Subtle variations in tissue - culture chemicals and Matrigel, or in different stem cell lines and how they are grown first in 2 - D culture, can have a big impact on how the organoids turn out, Novitch says.

It performs this critical service in embryonic development, growing organisms and in a few specialized adult cell lines, including stem cells.

Scientists have already reported progress in growing precursor cells for eggs and sperm from both iPS and embryonic stem cell lines.

The group reported growing multiple parthenogenetic embryonic stem cell lines by incubating eggs in a warm, low - oxygen culture medium.

To find methods for stemming the tide of liver - damaging microbes, Schnabl and team tried experimentally bumping up copies of the REG3G gene in intestinal lining cells grown in the lab.

NeuroStemcell is focused on the identification and systematic comparison of progenitor cell lines with the most favourable characteristics for mesDA and striatal GABAergic neuronal differentiation, generated either directly from human embryonic stem (ES) cells, from Neural Stem (NS) cells derived from ES cells or fetal brain, from induced Pluripotent Stem (iPS) cells or from in vitro short - term expanded neural progenitors from ventral midbrain grown as neurospheres (VMN, Ventral Midbrain Neurospheres) 4, and perform rigorous and systematic testing of the most prominent candidate cells in appropriate animals modstem (ES) cells, from Neural Stem (NS) cells derived from ES cells or fetal brain, from induced Pluripotent Stem (iPS) cells or from in vitro short - term expanded neural progenitors from ventral midbrain grown as neurospheres (VMN, Ventral Midbrain Neurospheres) 4, and perform rigorous and systematic testing of the most prominent candidate cells in appropriate animals modStem (NS) cells derived from ES cells or fetal brain, from induced Pluripotent Stem (iPS) cells or from in vitro short - term expanded neural progenitors from ventral midbrain grown as neurospheres (VMN, Ventral Midbrain Neurospheres) 4, and perform rigorous and systematic testing of the most prominent candidate cells in appropriate animals modStem (iPS) cells or from in vitro short - term expanded neural progenitors from ventral midbrain grown as neurospheres (VMN, Ventral Midbrain Neurospheres) 4, and perform rigorous and systematic testing of the most prominent candidate cells in appropriate animals models.

For the first time since the linkurl: National Institutes of Health; http://www.nih.gov/ released its new guidelines for the derivation of human embryonic stem cell (hESC) lines last summer, a line approved under the Bush administration has been recommended for inclusion into the growing federal registry of lines eligible for federal funding.

As researchers look ahead to potential clinical trials with stem cells, it is becoming apparent that few, if any, of these lines will have any therapeutic value, in part because they were grown along with «feeder» cells from mice.

Cells from these embryos can be used to create pluripotent stem cell «lines» — cell cultures that can be grown indefinitely in the laboratory.
