As a result, many researchers have focused on adult stem cells, [3] or stem cells isolated from adult humans that can be transplanted into damaged tissue. Because of their multi-potent capabilities, mesenchymal stem cell (MSC) lineages have been used successfully in animal models to regenerate articular cartilage and in human models to ...
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 ...
The transplanted cells also generate an immune response that helps to kill off the cancer cells; this process can go too far, however, leading to graft vs host disease, the most serious side effect of this treatment. [8] Another stem-cell therapy, called Prococvhymal, was conditionally approved in Canada in 2012 for the management of acute ...
Embryonic stem cells of the inner cell mass are pluripotent, meaning they are able to differentiate to generate primitive ectoderm, which ultimately differentiates during gastrulation into all derivatives of the three primary germ layers: ectoderm, endoderm, and mesoderm.
As opposed to mesenchymal stem cells, embryonic-like stem cells are not abundant in the amniotic fluid, making up less than 1% of amniocentesis samples. Embryonic-like stem cells were originally identified using markers common to embryonic stem cells such as nuclear Oct4, CD34, vimentin, alkaline phosphatase, stem cell factor and c-Kit. However ...
The FDA approved a phase I clinical trial with ViaCyte beta cells derived from human embryonic stem cell for the treatment of diabetes in August 2014. [15] The cells will be delivered in immunoprotective capsules and pre-clinical results in animal models showed remission of symptoms within a few months. [16]
