Stem cell tourism is the part of the medical tourism industry in which patients travel to obtain stem cell procedures. [109] The United States has had an explosion of "stem cell clinics". [110] Stem cell procedures are highly profitable for clinics. The advertising sounds authoritative but the efficacy and safety of the procedures is unproven.
Stem cells are being explored for use in conservation efforts. Spermatogonial stem cells have been harvested from a rat and placed into a mouse host and fully mature sperm were produced with the ability to produce viable offspring. Currently research is underway to find suitable hosts for the introduction of donor spermatogonial stem cells.
A stem cell possesses two properties: . Self-renewal is the ability to go through numerous cycles of cell division while still maintaining its undifferentiated state. Stem cells can replicate several times and can result in the formation of two stem cells, one stem cell more differentiated than the other, or two differentiated cells.
One step in that process is single cell phenotypic analysis, and the connection between the phenotype and genotype of specific stem cells. While current genomic screens are done with entire populations of cells, focusing in on a single stem cell will help determine specific signaling activity associated with varying degrees of stem cell differentiation and limit background due to heterogeneous ...
He supports federal funding for embryonic stem cell research on the already existing lines of approximately $100 million, $250 million for research on adult and animal stem cells, and creates the President's Council on Bioethics led by Dr. Leon Kass of the University of Chicago to "monitor stem cell research, to recommend appropriate guidelines ...
Stem Cell Research is a peer-reviewed open-access scientific journal covering research on stem cells. The journal was established in 2007 and is published 8 times per year by Elsevier. The editor-in-chief is Thomas Zwaka (Icahn School of Medicine at Mount Sinai).
