G-CSF of Blood and Brain
Loma Linda CA- We at StemCellPatents.com have described in various patents the relationship between hematopoietic stem cells and neural stem cells. Stunning examples include the ability of neurons to stimulate hematopoiesis, Patent # 6897060, the ability of the same hypoxic conditions that promote hematopoietic stem cell...Tuesday November 28th, 2006 @ 20:04:14 EST

Tolerogeneicity of Embryonic Stem Cells in Allogeneic animals
Iowa City, Iowa USA Due to the great interest generated by the first clinical use of embryonic stem cells we decided to see other papers in the area of immunological activities of embryonic stem cells. The possibility that embryonic stem cells can be immune suppressive and therefore transplanted across allogeneic barriers is very...Tuesday November 28th, 2006 @ 02:17:56 EST

Mesenchymal Stem Cells: The younger the better !
London, UK Guillot et al published in the Nov 22 edition of Stem Cells a paper entitled "Human first trimester fetal mesenchymal stem cells (MSC) express pluripotency markers, grow faster, and have longer telomeres compared to adult MSC." which suggests several advantages to regenerative uses of fetal derived mesenchymal stem cells as compared to the currently used bone marrow derived...Monday November 27th, 2006 @ 20:00:35 EST

First Clinical Use of ES Cells
Gujarat, India - To our knowledge the first-ever peer-reviewed publication describing clinical use of embryonic stem cells has appeared this week in the journal Transplantation Proceedings (Trivedi et al. Embryonic stem cell derived and adult hematopoietic stem cell transplantation for tolerance induction in a renal allograft recipient:-a case report.Transplant Proc. 2006...Sunday November 26th, 2006 @ 18:10:34 EST

Inflammation TWEAKs Stem Cell Expansion
Watertown, MA Girgenrath M et al published in today's online version of EMBO a paper entitled TWEAK, via its receptor Fn14, is a novel regulator of mesenchymal progenitor cells and skeletal muscle regeneration which demonstrates the ability of inflammatory stimuli to induce mesenchymal stem cell proliferation. The authors reported that the cytokine known as TNF-like weak inducer of...Sunday November 26th, 2006 @ 17:00:46 EST

Colon Cancer Stem Cell Revealed
Toronto Canada - Researchers at Princess Margaret Hospital in Toronto published in todays journal Nature the identification of a cell population within the bulk tumour mass that possesses the functional characteristics of a tumor stem cell. In a paper entitled "A human colon cancer cell capable of initiating tumour growth in immunodeficient mice." John Dick's group essentially demonstrated...Friday November 24th, 2006 @ 11:49:24 EST

Nose to Hair: Differentiation of Olfactory Stem Cells
Sydney Australia - In a study published in today's issue of Stem Cells, Australian scientists reported a unique methodology for coaxing olfactory adult stem cells to acquire the phenotype of cochlear hair cells. This finding is important because deafness results from loss of cochlear hair cells and the ability to generate these cells in vitro would conceptually open the door for cell therapy...Wednesday November 22nd, 2006 @ 21:18:19 EST

Lipid Stimulation of Mesenchymal Differentiation
Seoul South Korea - Jeon et al published today in the online version of the Journal of Cell Sciences that exposure of mesenchymal stem cells to the lipid sphingosylphosphorylcholine (SPC) induces differentiation into smooth muscle cells in a paper entitled "Sphingosylphosphorylcholine induces differentiation of human mesenchymal stem cells into smooth-muscle-like cells through a...Thursday November 16th, 2006 @ 22:40:39 EST
Electrical signals inducing stem cell differentation
Saitama Japan- In today's issue of the journal Stem Cells, Yamada et al reported that electrical stimulation of embryonic stem cells resulted in induction of differentiation into the neural lineage. In a paper entitled "Electrical stimulation modulates fate determination of differentiating embryonic stem cells", the authors demonstrated that embryonic stem cells differentiated by electrical...Thursday November 16th, 2006 @ 17:51:36 EST
Stromal-Like Environment Critical to Stem Cell Expansion
St. Louis, MO- It is long been suggested that the appropriate imitation of in vivo microenvironments is critical to successful culture, expansion, and differentiation of stem cells. In a paper which appeared in the Nov 9 online issue of Blood (Cytokine and integrin stimulation synergize to promote higher levels of GATA-2, c-myb, and CD34 protein in primary human hematopoietic progenitors...Wednesday November 15th, 2006 @ 01:20:28 EST
