There are legitimate case reports in credited journals of hyperdontia, or the condition of having supernumerary teeth. Such cases are often associated with congenital syndromes-- cleft lip and palate, trichorhinophalangeal syndrome, cleidocranial dysplasia, and Gardner's syndrome. I included a case report and a comprehensive review for you below. Case ...

I found a protocol by ATCC for NTERM2 cells, and it didn't mention any specific flask, so any cell culture flask would do. Since ATCC is basically a cell culture bank I trust that their protocol is valid.

There is no specific dye for stem cells. You would have to do an immuno-histochemical staining for stem cell markers such as Sox2/Oct4 etc. Usually stem cells have a distinct morphology (round and clustered). You can use Leishman's (or Romanowsky-Giemsa) stain.

From this article: iPSC's or induced pluripotent stem cells are somatic cells that have been driven to acquire an induced pluripotent cell state. Somatic cells can be any cell of the body except sperm cells, egg cells and undifferentiated stem cells. Investigators can induce these cells to 'return' to a stem cell like state by forcing the expression of key ...

When you look at the development of the embryo, at the beginning all cells are totipotent, meaning they can develop into any cell type of the body. This changes relatively fast by differentiation, which means that the totipotent cells develop into more specialized cell types, which then can not give rise to all cell types. So the different germ layers (meso, ...

This is too long for a comment, so I have to write it in here: Mostly this is because other cell lines are more practical in the lab. Stem cells are much more tricky to maintain - especially if you want to keep their stem cell properties. They only grow very slow, tend to differentiate when they get too much stress, cellular signals and so on and need ...

Stem cell therapies do in fact utilise viruses. In the examples cited, the stem cells were infected by viruses in vitro, genetically modified, and then reintroduced into the target as autologous transplants. The main issue at hand is that live viruses introduced directly would be targeted and destroyed by the immune system, which greatly reduces their ...

It would not be possible to differentiate CSC from normal population non-invasively and select them out. You may do a single cell expression analysis to say if a CSC is present in a population or not but there is no magic bullet method for eliminating them. Also there are several oncogenes and some of them are also required for usual stem cell function. HAT ...

Yes, stem cells can pass through blood vessels and capillaries (as @WYSIWYG points, these cells should be small enough to fit inside that capillary). The interesting thing is that they posses multiple mechanisms of transmigration. They are attracted by TNF-alpha activated endothelial cells [1] and can pass through by [1]: leukocyte-like diapedesis ...
