Stem cells, as a concept, originated as a theory in the 19th century to potentially allow certain tissues to self-renew. There are five types of stem cells, and MSC's are multi-potent, meaning they are cells that have the ability to develop into more than one type of specialized cell. Mesenchymal stem cells were originally discovered and ...
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.
Because mesenchymal stem cells may regenerate cartilage, cartilage growth in human knees using autologous cultured mesenchymal stem cells is under research and preliminary clinical use, and appears to be safe as of 2016. [11] An advantage to this approach is that a person's own stem cells are used, avoiding tissue rejection by the immune system ...
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.
Autotransplantation is the transplantation of organs, tissues, or even particular proteins from one part of the body to another in the same person (auto-meaning "self" in Greek [1]). The autologous tissue (also called autogenous, autogeneic, or autogenic tissue) transplanted by such a procedure is called an autograft or autotransplant. [2]
In particular, mesenchymal stem cells have been shown in animal models to regenerate cartilage. Recently, there has been a published case report of decrease in knee pain in a single individual using autologous mesenchymal stem cells. An advantage to this approach is that a person's own stem cells are used, avoiding transmission of genetic diseases.
The presence of varying cell types, including neurons, astrocytes, and oligodendrocytes, confirms the multipotency of these precursor cells. The evidence of self-renewal and multipotency serves to confirm the presence of neural stem cells within neurospheres, and emphasizes that neural stem cells comprise only a fraction of the neurosphere.

The stem cell market has grown largely along with the increasing awareness of stem cells in regenerative medicine. The Google web search big data analysis showed that the terms stem cell facelift and stem cell breast augmentation had 197,000 and 302,000 outcomes, respectively, according to the American Society of Plastic Surgeons.
