http://www.hindawi.com/journals/sci/aa/150609/ - our new work in Stem Cells International. I'm in love with this type of stem cells but need to admit that there are still lots of problems. I hope this paper would be useful for you.

Abstract
Although the characteristics of SC, including UC-derived cells, are a dramatically discussed issue, this review will focus particularly on some controversial issues regarding clinical utility of cells isolated from UC tissue. UC-derived cells have several advantages compared to other types and sources of stem cells. The impact of UC topography on cell characteristics is briefly discussed. The necessity to adapt existing methods of cell isolation and culturing to GMP conditions is mentioned, as well as possible cryopreservation of this material. Light is shed on some future perspectives for UC-derived cells.

Tonsil-Derived MSC

It was quite predictable and here it is:

The liver provides critical functions, such as ridding the body of toxins. Its failure can be deadly, and there are few options for fixing it. But scientists now report in the journalACS Applied Materials & Interfaces a way to potentially inject stem cells from tonsils, a body part we don’t need, to repair damaged livers — all without surgery.
Byeongmoon Jeong and colleagues point out that currently, the only established method for treating liver failure or severe cases of liver disease is complete or partial transplantation. But the need is much greater than the number of available organs. Plus, surgery has inherent risks and a hefty price tag. A promising alternative in development is transplanting liver cells. One such approach involves using adult stem cells to make liver cells. Stem cells from bone marrow could be used, but they have limitations. Recently, scientists identified another source of adult stem cells that could be used for this purpose — tonsils. Every year, thousands of surgeries are performed to remove tonsils, and the tissue is discarded. Now it could have a new purpose, but scientists needed a way to grow them on a 3-D scaffold that mimics real liver tissue. Jeong’s team set out to do just that.
The researchers encapsulated tonsil-derived stem cells in a heat-sensitive liquid that turns into a gel at body temperature. They added substances called growth factors to encourage the stem cells to become liver cells. Then, they heated the combination up to a normal body temperature. The result was a 3-D, biodegradable gel that contained functioning liver cells. The researchers conclude that the same process has promise — with some further tweaking for ideal conditions — as an injectable tissue engineering technique to treat liver disease without surgery.

I think it could be really possible to obtain stem cells from different tissues.

Gremlins Sabotage the Mechanisms of Cancer Stem Cell Differentiation

Gremlins Sabotage the Mechanisms of Cancer Stem Cell Differentiation - that's not a joke. It's a title of the new paper at Cancer Cell Volume 25, Issue 6, 16 June 2014, Pages 716–717. Joan Seoane made an interesting research on cancer stem cells. 

Here is the abstract: BMP is highly expressed in glioblastoma and promotes differentiation of cancer stem cells (CSCs). Recently, Yan and colleagues found the explanation to this apparent paradox by showing that the antagonist of BMP, Gremlin1, is secreted by CSCs to protect them against the BMP-induced differentiation.
