The main challenges for SCNT cloning of human embryonic stem cells

human-cloning1

It was intriguing last week to read about another advance in somatic cell nuclear transfer (SCNT)-based therapeutic cloning of human embryonic stem cells (hESC). The first such work was published last year by Mitalipov’s group from OHSU. This second paper to produce so-called nuclear transfer hESC (NT-hESC) made the important advance to show that it could …

Adult human therapeutic cloning of embryonic stem cells by SCNT

Human-SCNT1

An international team of stem cell scientists has replicated human therapeutic cloning to make embryonic stem cells via somatic cell nuclear transfer (SCNT). The team was led by Drs. Dong Ryul Lee of CHA Stem Cell Institute in Korea and Robert Lanza of Advanced Cell Technology (ACT) and reported the advance in the Chung, et …

Human cloning successfully makes embryonic stem cells

For the first time ever, scientists have successfully used somatic cell nuclear transfer (SCNT) via the process of therapeutic human cloning to generate normal human embryonic stem cells (hESC). Recall that there are two kinds of human cloning: therapeutic (which is reported in the new paper discussed in this post) and reproductive, which is making …

The war propaganda myth of adult versus embryonic stem cells hurts everyone

war

If someone is not in a war, but someone else declares war on them or actually attacks them, I would say the reality is that war has started and there are two opposing sides. However, has that happened when it comes to stem cells? Are we in a stem cell war? There have been times …

Key points about adult versus embryonic stem cells

Knoepfler lab stem cells

What with the Mississippi “personhood” amendment up for a vote today and also the Vatican Adult Stem Cell Conference beginning tomorrow, I thought today was a good time for a post about adult versus embryonic stem cells. Does stem cell research have to be either/or? Adult or stem? Can’t someone be for both adult and …

How would the Supreme Court rule on embryonic stem cells?

It seems reasonably likely that in the end, the final say on the embryonic stem cell case one way or another will be decided by the U.S. Supreme Court. While yesterday brought a victory for science and patients and logic, this was just one battle, not the war. The war that opponents of ES cell …

Perspectives on Vatican Stem Cell Meeting: CIRM, Embryonic & Adult Stem Cells

Vatican-stem-cell-meeting

Over the years, the Vatican has expressed interest and even invested money in the adult stem cell field. Not surprisingly, they’ve also been critical of embryonic stem cell research. Interestingly their own stem cell meetings have at times stimulated heated debate for various reasons and one was even cancelled with at least part of the reason related to …

Do human Very Small Embryonic-Like Stem Cells (VSEL) exist as a normal population of actual stem cells?

Supposedly there is a type of normal adult stem cell that intrinsically possesses many of the same properties as embryonic stem cells (ESCs). No reprogramming needed. No blastocysts needed. These reportedly amazing cells, called Very Small Embryonic-Like Stem Cells (VSELs), can in theory be isolated from umbilical cord blood (UCB) or even bone marrow. Yet …
