Recent developments. Until recently, the use of cultured mesenchymal stem cells to regenerate cartilage has been primarily in research with animal models. There are now, however, two published case reports of the above technique being used to successfully regenerate articular and meniscus cartilage in human knees.
Stem cell tourism is the part of the medical tourism industry in which patients travel to obtain stem cell procedures. The United States has had an explosion of "stem cell clinics". Stem cell procedures are highly profitable for clinics. The advertising sounds authoritative but the efficacy and safety of the procedures is unproven.
For the cell type, see Stem cell. Stem-cell therapyuses stem cellsto treat or prevent a disease or condition.[1] As of 2016[update], the only established therapy using stem cells is hematopoietic stem cell transplantation.[2] This usually takes the form of a bone marrowtransplantation, but the cells can also be derived from umbilical cord blood ...
Autologous stem-cell transplantation is distinguished from allogenic stem cell transplantation where the donor and the recipient of the stem cells are different people. [2] It can be also used as an Assisted reproductive technology to improve the reproductive outcomes. In a first step the bone marrow derived stem cells are mobilized.
Induced pluripotent stem cells (also known as iPS cells or iPSCs) are a type of pluripotent stem cell that can be generated directly from a somatic cell. The iPSC technology was pioneered by Shinya Yamanaka and Kazutoshi Takahashi in Kyoto, Japan, who together showed in 2006 that the introduction of four specific genes (named Myc, Oct3/4, Sox2 ...
Earlier this month, popular instructors Kristin McGee, Kendall Toole, and Ross Rayburn announced they were leaving.

Stem cells are cells found in all multi-cellular organisms. They were isolated in mice in 1981, and in humans in 1998. [1] In humans there are many types of stem cells, each with varying levels of potency. Potency is a measure of a cell's differentiation potential, or the number of other cell types that can be made from that stem cell.
