STEM CELLS AND REGENERATIVE MEDICINE : CORD BLOOD BANKING AND ITS THERAPEUTIC APPLICATION
Abstract :
Stem cells can give rise to any tissue found in the body and thus provide nearly limitless potential for medical applications . Stem cells have the great potential to develop into many different cell types in the body during early life and growth. They serve as a repair system . Due to unlimited therapeutic applications of stem cells , they continue to be of great importance scientifically and

Human embryonic stem cells . Patient-specific therapy.
METHOD :
Articles for this review were selected from Pubmed Central and Medline databases and proquest databases.
Introduction :
Stem cells are able to generate mature terminally differentiated cells of atleast one lineage and possess the capacity of self-renewal .Stem cells can be categorized as totipotent, pluripotent or multipotent according to their developmental potential. (Takahashi and Yamanaka 2007).
Stem Cell Classification Based on Differentiation Potential:
Stem cells can be classified based on their ability to differentiate. They are classified into following five types :
Totipotent Cells: Totipotent cells are found in early stage of development .The totipotent cells forms the embryo and the placenta and differentiate into both embryonic and extraembryonic tissues.
Pluripotent Cells: Pluripotent cells differentiate into cells that arise from three germ layers called – ectoderm , endoderm and mesoderm , from which other tissues and organs develop.
Oligopotent Cells: oligopotent are capable of self renewal and differente into many tissue types.
Unipotent Cells: unipotent cells are capable of self renewal and differentiate into only one single type of cell.
Multipotent Cells: They are found in most tissues and differentiate into cells from a single germ layer. (Kolios, 2012) Sources of Stem Cells for Regenerative Medicine:
There are a number of cardiovascular , neurological
The unique properties of stem cells are that they are capable of dividing and renewing themselves for a long time. This means they can multiply as many times as they want and grow into lots of different types of cells. They are also under certain physiologic and experimental conditions. They can produce tissue or organ-pacific cells with special functions. There are three classifications of stem cells. There are Totipotent, Pluripotent and Multipotent. Each one of these classifies stem cells in a certain way. Totipotent cells can change into all cells types, Pluripotent cells can change into most cell types and Multipotent cells can change into certain cell types. There are two major types of stem cells, Embryonic and Adult. Although they are both major types of stem cells they are very different from each other. Embryonic stem cells can change into all types of cells and Adult stem cells can change only into certain types of cells. Embryonic stem cells are classified as Totipotent and Pluripotent. Adult stem cells are classified as Multipotent. Another reason why Embryonic and Adult stem cells are different is because they have
become many different types of cells in the human body. What might start off as a stem cell
Stem cells are the first form of the cells of a multicellular organism and are undifferentiated cells. There are 3 different types of stem cells. This includes Embryonic stem cells, tissue-specific stem cells, induced pluripotent stem cells. Stem cells are capable of self-renewal.They can divide and produce cells that can to become more specific cell types, tissues or organs.
Contained in the human body there are more than 220 different cell types being derived from a group of cells called embryonic stem cells. Being located in what is known as the inner cell mass of a blastocyst which is a young embryo about four to five days old. The uniqueness of these cells and what defines them is that they are pluripotent, meaning they are able to differentiate into any 3 germ layers. These layers include the endoderm, mesoderm, and ectoderm. Being able to
The stem cells that originate in the inner mass found in embryos a few days old are grown in the laboratory and are referred to as embryonic stem cells. A branch of these cells are embryonic germ cells, and these are derived from egg and sperm cells in a five to ten week old fetus. Both of these types of stem cells are pluripotent. In embryonic stem cells, the blastocyst cells divide and eventually develop into all of the tissues and organs of human beings. Embryonic stem cells are capable of being grown in the laboratory from blastocysts and made to differentiate into nerve, liver, muscle, blood, and other cells. (Morgani, et al.
For starters, a stem cell is an undifferentiated cell that is capable of regenerating itself or becoming induced into a specific tissue or organ for specialized functions under certain physiological functions. All stem cells have the following three things in common: they are capable of renewing and dividing themselves over an extended period of time, they are not specialized, and they are able to give rise
Cellular Differentiation is when a less specific cell becomes a more particular cell. Each tissue has their own type of cell.
According to Alenzi, “Stem cells are immature, unspecialized cells that their developmental direction has not yet been determined” (19929), and because they do not yet serve any meaningful purpose, stem cells are capable of becoming virtually any specialized cell in the body; they can become nerve cells, blood cells, skin cells, and just about any other cell you can think of.
All of these specialised cells originate from a single type of cell, stem cells. A stem cell is a cell that is not yet specialised. Before a stem cell can be specialised it must go through a process called differentiation and once the differentiation pathway of a stem cell has been decided, it can no longer become another type of cell. Different types of stem cells have different levels of potential. A stem cell that can become every type of cell in the body is called pluripotent and a stem cell that can become only some types of cells is called
Now as we all grow up we ponder the idea of what our profession will be and the same approach comes into play with stem cells. There are two main types of stem cells, which are embryonic stem cells and adult stem cells. An embryonic stem cell is a undifferentiated cell that can give rise to all of the bodies cells and your existence in whole by choosing its profession. While most cells can only recreate more of its own kind;
There are two types of cells: adult stem cells and embryonic stem cells. Embryonic stem cells are produced when a

There are also cells called Pluripotent cells. These cells are meant to rise cells from three germ layers. These germ layers are known as endoderm, mesoderm, and ectoderm.
The totipotent cells then turn into a blastocyst by many types of cell division, which forms a lot of cells in side.
