History and Future Scope of Stem Cell Therapy
Stem cells are the initial body cells from which all other cells with special functions are produced. Under a controlled environment or clinical laboratory in the body, these cells divide to form more cells, called daughter cells. Due to the advent of modern health science, these cells play a major role in understanding the occurrence of diseases, generation of advanced regenerative drugs, and drug discovery. There are certain sources such as fetuses, bone marrow, body fat and umbilical cord blood among others, where stem cells are produced.

Stem cells have the ability to differentiate into specific cell types. The two defining characteristics of a stem cell are perpetual self-renewal and the ability to differentiate into a particular adult cell type. There are two major classes of stem cells: pluripotent that can become any cell in the adult body, and polymorphisms that are limited to becoming more limited populations of cells. Cell sources, characteristics, differentiation and therapeutic applications are discussed. Stem cells have considerable potential in tissue regeneration and repair but still need to know about their biology, manipulation, and protection before their full therapeutic potential can be achieved.
Stem cell research has been widely investigated globally to enhance human health in medical settings. For this, creating public awareness of stem cell research is important for realizing this potential. The main role of stem cells is to replace dying cells and regenerate damaged tissues. Based on extensive stem cell research results, many scientists have claimed that cells can potentially generate treatments and treatments for various diseases, including cancer, heart disease, and others. Newly developed stem cell therapy has the potential to replace disease, producing cells.
Stem cells have the capacity to manufacture every tissue in the human body, so there is considerable potential for future therapeutic use in tissue regeneration and repair. For cells to fall under the definition of "stem cells", they must demonstrate two essential characteristics. First, stem cells must have unlimited self-renewal ability to produce progenitors similar to those of stem cells. This property is also true of cancer cells that divide in an uncontrolled manner while stem cell division is highly regulated. Therefore, it is important to note the additional requirement for stem cells; They should be able to give rise to a particular cell type that becomes part of a healthy animal.
Patients have now started relying on stem cell therapy, which has long-term positive results. The number of potential therapies is increasing in clinical trials. The FDA has approved very few stem cell therapies. For example, in 2019, federaltinib is approved by the FDA for first-line treatment for myelofibrosis. Bone marrow transplants are widely used stem cell based therapies. Blood-forming stem cells were first used in the clinic. This stem cell therapy has benefited thousands of patients who have leukemia.
In recent years, stem cell therapy has become a very promising and advanced scientific research topic. The development of treatment methods has given rise to great expectations. This paper is a review focused on the discovery of various stem cells and possible therapies based on these cells. The origin of stem cells is controlled by laboratory steps of stem cell culture and derivation. Quality control and teratoma formation assay are important procedures in assessing the properties of tested stem cells. Derivative methods and the use of controlled media are important to determine appropriate environmental conditions for controlled discrimination. In many types of stem tissue applications, the use of graphene scaffolds and the ability of extracellular vesicle-based therapy require attention due to their versatility. The review is summarized by the challenges that stem cell therapy must overcome to be accepted worldwide. A wide variety of possibilities make this state-of-the-art medicine a turning point in modern medicine, providing hope for untreated diseases.

Researchers are investigating further on stem cell therapy in autoimmune disorder. Other adult stem cell-based therapies are under clinical trials. Hematopoietic stem cells are currently used to treat more than 80 medical diseases, including immune system diseases, blood disorders, neurological disorders, metabolic disorders, genetic disorders and many types of cancers such as leukemia, lymphoma, etc.
