Mammalian Stem Cells - Research Paper Example However, research has raised ethical and religious issues which oppose the duplication of body tissues. Our research shows that the benefit of mammalian stem cell culture has increasingly become important over the years in the production of antibodies, hormones and other vaccines essential for the treatment of various body ailments. Introduction Stem cells are found throughout the body of an animal. They occur in numerous numbers in the tissues such as the brain, adipose and the muscles. Stem cells help in maintaining the functioning and integrity of the tissues throughout the lifetime of an organism. This is because their main role is the replacement of the differentiated cells which are lost through attrition or other damages. Mammalian stem cells have the capacity of proliferating while maintaining their primitive states. In addition, they also differentiate into other specialized lineage. Due to their expansion and differentiation capabilities, there is high promise in the develo pment of cell based models of human diseases. This is because such diseases can be treated during the cell replacement therapies. Engineers and researchers have developed a theoretical approach and other cell culture systems. All this technologies are vital in the control of stem cell fate which is the ultimate goal to scale up the clinical grade during the production of stem cell therapies. Advancement of stem cells science and broadening of cell culture technology has led to arising of therapies and tissue engineering. This paper work gives an overview of tissue engineering and therapies of mammalian stem cells. It describes the current progress and prospect of stem cells research and its potential application in the medical treatment. Discussion Stem cell technologies and tissue engineering have currently emerged rapidly with an approach of addressing disease problems and other serious body complications. The two technologies are the interdisciplinary fields that use the principl e of bioengineering and other sciences towards assembling of the stem cells. This is important in restoring, maintaining and improving the functioning of the cell following their damage by disease or other traumatic processes. It is, therefore, easy to manage incurable diseases and loss of tissue through the successful therapies of artificial transplant of body organs. The general principles of stem cell engineering and tissue therapy are the combination of living cells with other synthetic scaffold to build three dimension living cells. The three dimensional cell structures aid in guiding the growth, organization and differentiation of cells. Synthetic scaffold should be biocompatible and designed in a way that it assists in meeting the nutritional and biological needs of different cells on the body. Their growth factors should be made of soluble peptides that are capable of binding the cellular receptors that provide permissive or preventive response of the cell towards differenti ation of the body tissue (Kim and Evans 12). Therapy And Tissue Engineering Fundamentals The concept of tissue engineering started in 1933 when tumor cells from the mouse demonstrated survival ability when they were implanted in the abdominal cavity of an embryo chick. Few decades later the chick’s pancreatic beta cells demonstrated that they responded by releasing insulin depending on the concentration of glucose in the body. In 1980, through the principle of tissue enginee

Using of Tress to improve the quality of urban spaces Research Proposal

Using of Tress to improve the quality of urban spaces - Research Proposal Example This contributed to numerous adverse effects brought about by the lack of vegetation. Research has highlighted that planting trees in urban spaces can contribute to numerous positive changes, improving the quality of life in urban areas. Previous studies have focused on understanding how the planting of trees in urban spaces can contribute to better climatic conditions in urban areas. Experts in this field have relied on different methodologies for assessing the impacts of different types of trees planted in urban spaces (Akbari & Pomerantz, 2001). Without doubt, the need to restructure the architecture of urban spaces by planting trees is becoming more evident in the modern society. With the increasing rates of global warming, human beings have no option, but to modify the urban spaces by planting more trees. Although there has been an emphasis on the need to plant trees on urban spaces, few of the residents in these areas recognize the benefits of trees to them. Previous studies have focused on generating scientific evidence on how trees can improve the quality of life in urban areas. Evidently, there is minimal research, which highlights how urban residents appreciate the benefits of trees and contribute positively to planting more trees in community programs. In order to ascertain the benefits of trees in improving the quality of life, the opinion of environmentalists is of critical importance. Few researchers in the past have given regard to the opinions of the environmentalists in the past. If the efforts of planting trees are to be more successful, then both environmentalists and residents of urban places should focus on a similar agenda. Therefore, this research will assess how trees in urban places improve the quality of life in accordance with environmentalists and local residen ts (Camacho-Cervantes et al, 2014). The significance of this research is to
