STEM CELLS In this report, I mainly focused on Stem-Cells. You will read about Stem-Cells and its history from the moment this term was known. Also, you will know the Sources, properties, and the types of Stem-Cells. In addition, you will know some of the pros and cons researches about Stem-Cells. Stem-Cells are cells that have the ability to divide and multiply and renew itself. • Sources of Stem-Cells: 1- The first source is Bone Marrow. 2- The second source is Adipose Tissue (lipid cells). 3- The third source is The Blood. • Stem cells types: 1- The first type of Stem Cells is Embryonic stem cells (ES cells) . 2- The second type of Stem Cells is Adult stem cells. 3- The third type of Stem Cells is…show more content…
• 1997: Cloned lamb from stem cells. • 1997: Leukemia origin found as hematopoietic stem cell, indicating possible proof of cancer stem cells. “In 1998, Thompson, from the University of Wisconsin, isolated cells from the inner cell mass of early embryos and developed the first embryonic stem cell lines. During that exact same year, Gearhart, from Johns Hopkins University, derived germ cells from cells in fetal gonad tissue; pluripotent stem cell lines were developed from both sources. Then, in 1999 and 2000, scientists discovered that manipulating adult mouse tissues could produce different cell types” . This meant that cells from bone marrow could produce nerve or liver cells and cells in the brain could also yield other cell types. These discoveries were exciting for the field of stem cell research, with the promise of greater scientific control over stem cell differentiation and proliferation. Sources of Stem-Cells There are three sources of autologous adult stem cells in humans: 1. The first source is Bone marrow. Bone marrow requires extraction by harvesting, that is, drilling into bone (typically the femur or iliac crest). 2. The second source is Adipose Tissue (lipid cells). Adipose Tissue which requires extraction by harvesting, that is, drilling into bone (typically the femur or iliac crest). 3. The third source is The Blood. Blood requires extraction through apheresis, wherein blood is drawn from the donor (similar to a blood
