History of Stem Cells

Summary of the History of Stem Cells In this article we will explain the history of stem cells. There are many ways to collect stem cells. Stem cells can be used for correct or incorrect reasons. People can use them to treat and cause injuries. Most people use stem cells to treat deadly diseases. Researchers have put stem cells in the scientific community and make people understand that it is Leroy Stevens. It was the teratoma mouse that he first encountered the stem cell. Most people do not understand the need for stem cells.

The history of adult stem cell research began over 60 years ago. In the 1950's, researchers discovered that bone marrow contains at least two stem cells. A group called hematopoietic stem cells forms all kinds of blood cells in the body. A second group of people called bone marrow stromal stem cells (also known as mesenchymal stem cells, or some stem cells) was discovered several years later. These nonhematopoietic stem cells form a small fraction of the stromal cell population in the bone marrow and produce bone, cartilage and adipocytes that support the formation of blood and fibrous connective tissue.

Mesenchymal stem cells are reported to exist in many tissues. Bone marrow-derived cells (bone marrow stromal stem cells, bone stem cells) produce a variety of cell types: osteocytes (osteoblasts and bone cells), chondrocytes (chondrocytes), adipocytes (adipocytes) Support stromal cells. Been formed. However, it is unclear how similar or different mesenchymal cells from a non-myeloid source are derived from the bone marrow stroma. Skin stem cells occur at the base of the epidermis and the base of the hair follicle. Epidermal stem cells produce keratinocytes that migrate to the surface of the skin and form a protective layer. Follicular stem cells produce hair follicles and epidermis
