A cell bank in its simplest form is a collection of containers of cryopreserved cells that are intgral part of a homogenous cell suspension derived from a single culture of cells.Cells are stored at ultra-low temperature and in this state the cells remain viable indefinitely. On thawing they are able to divide again. A cryopreserved [...]
How Are Embryonic Stem Cells Grown In Labortary?
March 20, 2009 By Leave a Comment
Embryonic stem cells,are derived from embryos that develop from eggs that have been fertilized in vitro—in an in vitro fertilization clinic—and then donated for research purposes with informed consent of the donors. The embryos from which human embryonic stem cells are derived are typically four or five days old and are a hollow microscopic ball [...]
What Are Adult Stem Cells and Where Are They Found?
March 19, 2009 By Leave a Comment
An adult stem cell is an undifferentiated cell found among differentiated cells in a tissue or organ. These cells can renew themselves and can differentiate to yield the major specialized cell types of the tissue or organ. The primary roles of adult stem cells in a living organism are to maintain and repair the tissue [...]
Brain Tissue Created From Stem Cells

Japanese researchers claim to have created functioning human brain tissue from stem cells, a world first that has raised new hopes for the treatment of disease. Stem cells taken from human embryos have been used to form tissues of the cerebral cortex, according to experts at the government backed research institute Riken. The tissues self-organised [...]

What Are Stem Cells?
March 1, 2009 By Leave a Comment
Stem cells are special types of cells which have the characteristic ability to renew themselves through mitotic cell division [ A kind of cell division in which two similar cells are produced from one cell] and differentiating into a diverse range of specialized cell types. Stem cells are present in most multi-cellular organisms. The two [...]

I am Dr Arun Pal Singh. You might know me from boneandspine.com. I would be writing on issues related to stemcells in this blog. I needed a separate place to write on this topic as this topic is itself quite vast with all kind of possible ramifications. Research in stem cells is quite promising and [...]
