In relation to human cells
In relation to human cells:- Outline the microscopic structure and function of the main types of cells found in human bone. Bone cells are a very important feature of bones as they built tissue for support as well as actually forming and replacing bone itself. (Gunn, 2007) There are three main different types of bone cell in bone tissue. Osteoblasts, osteocytes and osteoclasts. (Thibodeau, 2007). All three of these cells differentiate in structure. Osteoblasts have a reticulum which is not very well developed. They have loose inorganic ctystals which clearing show bone destruction. Their structure like so, is organised for the synthesis of protein to form a bone matrix. (Cameron, Paschall and Robinson, 1967). They occur along a surface and usually lie adjacent to each other upon lamellae which they secrete. They are known as bone-forming cells and are small cuboidal cells in shape. (King., 2009). Osteocytes are small cells. They are secreted from osteoblasts are isolated from one another in individual lacunae. The cell has tiny canaliculi which extend out to undertake the cell processes. They are divided by gaps but are close enough for means of communication and nutrient supply with one another. (King, 2009). Osteoclasts can be known as the bone-removing cell. They are a large cell and have multiple nuclei. They occur in small hollows which erode into the surface.
DNA research paper. The Ligation of EGFP cDNA into pET41a(+)
Shanni He Biol 100K Prof. Jeremy Lee TA: Kasturi Malaviya The Ligation of EGFP cDNA into pET41a(+) I. Introduction Over the course of the last few weeks, we conducted experiments in which our goal was to successfully ligate EGFP cDNA into pET41a(+) in order to transform our recombinant expression plasmids into clones of E. coli. After growing these cultures on varieties of agar plates, we attempted to isolate our recombinant plasmid DNA and ran multiple tests in order to confirm that the EGFP insert worked. GFP was first cloned in 1994 from the jellyfish Aqueorea victoria (Prasher et al., 1992). This useful gene glows green under specific lights allowing us to see when and where proteins appear. The type of GFP we used in our lab was EGFP, which is a humanized version of GFP (Yang et al., 1996). Today, GFP has become one of the most widely used proteins in biochemistry and has sparked man `` y new discoveries in gene expression and protein targeting. In order to clone EGFP, we utilized multiple procedures of recombinant DNA technology. This technology allows scientist to produce DNA artificially by extracting DNA from two different sources and combining them into a single molecule. The first successful production was done in 1972 at Stanford University, which opened a new horizon in drug development and medical discoveries. Human insulin, which is used to help
Stem Cells: Self-Renewal, Differentiation, and Heterogeneity
Project Update #1 Stem Cells: Self-Renewal, Differentiation, and Heterogeneity Joe Buran, Nick Rotella, Karamveer Birthare Introduction- Stem cells are biological cells found in all multi-cellular organisms, and have the potential to develop into several different types of cells in the body during their early life and throughout growth. They also play a major role in the regeneration of many tissues, as they continue to divide almost without limit as long as the organism is still alive. After a stem cell divides, it can either remain a stem cell or continue to grow, or it can differentiate into a more specific cell with a specialized function. Heterogeneity of Stem Cells- The classical definition of a stem cell requires that it possesses two properties, or metastable cell states. The first property, self-renewal, means that they have the ability to go through numerous cycles of cell division while maintaining the undifferentiated state. Secondly, they must possess potency. This is the ability under certain physiological conditions to become, or differentiate, into tissue or organ-specific cells with defined tissues. However, in other areas and tissues of the body, stem cells may only divide under special biological conditions. The ability of a stem cell to maintain both metastable cell states is referred to as stem cell heterogeneity. Various groups of scientists have
