Anatomy of stem cells

Human embryonic stem cells are important for the understanding of biologic mechanisms and their potential for treatment, and for toxicology studies. Mesenchymal stem cells can produce a good environment with chemical factors and signals to serve as anti-apoptotic, immune modulator and angiogenic, and can support regeneration in damaged tissues and induce faster and better wound healing. Stem cells have recently been shown in cancer tissue; these play a major role in the progression of cancer and the principal obstacle in treatment due to their resistance. Stem cells may participate in tissue homeostasis and regeneration which shows their capacity for cell therapies which makes them an amazing source for the clinical translation to treatment of diseases. Therefore, better understanding of the behavior of these cells and the mechanisms they use are important. Keywords: cancer; embryonic; hematopoietic; mesenchymal; pluripotent; stem cell
