Sentences with phrase «characteristics of embryonic stem cells»

The researchers took skin cells from the tails of sickle cell mice and inserted copies of four genes that made the cells take on the characteristics of embryonic stem cells.

These cells reportedly possessed many of the same characteristics of embryonic stem cells, without requiring the ethically problematic destruction of embryos.

Future research should not only compare how embryonic stem cells, iPS cells and adult stem cells differentiate, but focus on what effects the niche in which these cells will reside, when transplanted, will have on their characteristics, including tendencies to mutate into cancer cells, notes cell and stem cell biologist Olga Genbacev at the University of California, San Francisco, (U.C.S.F.) School of Medicine.

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.

Yamanaka and Takahashi began their search by studying embryonic stem cells in the hope of identifying the genes that underlie essential stem cell characteristics, such as pluripotency and proliferation, a cell's ability to replicate itself.

While it is widely accepted that embryonic stem cells (ESCs) have the ability to become any type of cell, the molecular causes for this characteristic are still under much investigation, although one suspected player is chromatin.

A human embryonic stem cell is reined in — prevented from giving up its unique characteristics of self - renewal and pluripotency — by the presence of a protein modification that stifles any genes that would prematurely instruct the cell to develop into heart or other specialized tissue.
