Human Embryonic and Induced Pluripotent Stem Cell Research Trends: Complementation and Diversification of the Field

Stem cells for spine surgery.

TLDR
Stem cell therapy has received the attention of spinal surgeons due to its potential benefits in the treatment of neural damage, muscle trauma, disk degeneration and its potential contribution to bone fusion.

The STAP Flap, the CIRM Squirm, and Lab Morality

“Reputation in science is everything,” said Alan Trounson to David Cyranoski. “Once gone, it's extremely hard to get back.”1As a bioethicist, I have to say I admire the worldwide scientific communi...

Finding the niche for human somatic cell nuclear transfer

Does human somatic cell nuclear transfer have a future after the discovery of induced pluripotent stem cells?

Genomic stability in reprogramming.

Reprogramming and development in nuclear transfer embryos and in interspecific systems.

Nuclear genome transfer in human oocytes eliminates mitochondrial DNA variants

TLDR
The potential of nuclear genome transfer between unfertilized oocytes of two donors to prevent the transmission of mitochondrial mutations is demonstrated and mitochondrial respiratory chain enzyme activities and oxygen consumption rates are indistinguishable from controls.

Towards germline gene therapy of inherited mitochondrial diseases

TLDR
Although some ST oocytes displayed abnormal fertilization, remaining embryos were capable of developing to blastocysts and producing embryonic stem cells similar to controls.

Human Embryonic Stem Cells Derived by Somatic Cell Nuclear Transfer

Offspring from Oocytes Derived from in Vitro Primordial Germ Cell–like Cells in Mice

TLDR
It is shown that female (XX) embryonic stem cells and induced pluripotent stem cells in mice are induced into primordial germ cell–like cells (PGCLCs), which, when aggregated with female gonadal somatic cells as reconstituted ovaries, undergo X-reactivation, imprint erasure, and cyst formation, and exhibit meiotic potential.

Screening ethnically diverse human embryonic stem cells identifies a chromosome 20 minimal amplicon conferring growth advantage

TLDR
Of these genes, BCL2L1 is a strong candidate for driving culture adaptation of ES cells, and single-nucleotide polymorphism analysis revealed that they included representatives of most major ethnic groups.
