Stem cell & Genetic clinical research

Stem cells are biological cells that can differentiate into other types of cells and can divide to produce more of the same type of stem cells. They are found in multicellular organisms.  In adult organisms, stem cells and progenitor cells act as a repair system for the body, replenishing adult tissues. In mammals, there are two broad types of stem cells: embryonic stem cells, which are isolated from the inner cell mass of blastocysts, and adult stem cells, which are found in various tissues. Genetics is the fundamental basis of any organism so understanding of genetics will provide a powerful means to discover hereditary elements in disease etiology. In recent years, genetic studies have shifted from disorders caused by a single gene (e.g. Huntington’s disease) to common multi-factorial disorders (e.g. hypertension) that result from the interactions between inherited gene variants and environmental factors, including chemical, physical, biological, social, infectious, behavioural or nutritional factors. Molecular genes were known to exist on chromosomes, chromosomes are composed of both protein and DNA, and scientists did not know which of the two is responsible for inheritance.
