Cord blood, which contains powerful stem cells, comes from a newborn's umbilical cord and is collected immediately after birth. Once the umbilical cord has been clamped and cut, the remaining blood in the umbilical cord is drawn into a collection bag

Cellular differentiation is the progression, whereas a cell changes from one cell type to another. Variation occurs numerous times during the development of a multicellular organism as it changes from a simple zygote to a complex system of tissues and cell types. Differentiation continues in adulthood as adult stem cells divide and create fully differentiated daughter cells during tissue repair and during normal cell turnover. Some differentiation occurs in response to antigen exposure. Differentiation dramatically changes a cell's size, shape, membrane potential, metabolic activity, and responsiveness to signals. These changes are largely due to highly controlled modifications in gene expression and are the study of epigenetics. With a few exceptions, cellular differentiation almost never involves a change in the DNA sequence itself. Thus, different cells can have very different physical characteristics despite having the same genome.

Somatic cell therapy is the administration to humans of autologous, allogeneic, or xenogeneic living cells which have been manipulated or processed ex vivo. Manufacture of products for somatic cell therapy involves the ex vivo propagation, expansion, selection. Somatic cell therapy is viewed as a more conservative, safer approach because it affects only the targeted cells in the patient, and is not passed on to future generations. Somatic gene therapy represents mainstream basic and clinical research, in which therapeutic DNA (either integrated in the genome or as an external episome or plasmid) is used to treat disease. Most focus on severe genetic disorders, including immunodeficiencies, haemophilia, thalassaemia and cystic fibrosis. Such single gene disorders are good candidates for somatic cell therapy.

 An abnormal mass of tissue, tumors are a classic sign of inflammation, and can be benign or malignant.  Tomour usually reflect the kind of tissue they arise in. Treatment is also specific to the location and type of the tumor. Benign tumors can sometimes simply be ignored, cancerous tumors; options include chemotherapy, radiation, and surgery.

Metabolism is the set of life-nourishing chemical transformations within the cells of living organisms. These enzyme-catalyzed reactions allow organisms to grow and reproduce, maintain their structures, and respond to their environments. Metabolism is divided into two categories: catabolism, the breaking down of organic matter by way of cellular respiration, and anabolism, the building up of components of cells such as proteins and nucleic acids. 

The most well-established and widely used stem cell treatment is the transplantation of blood stem cells to treat diseases and conditions of the blood and immune system, or to restore the blood system after treatments for specific cancers. Since the 1970s, skin stem cells have been used to grow skin grafts for patients with severe burns on very large areas of the body. Only a few clinical centers are able to carry out this treatment and it is usually reserved for patients with life-threatening burns. It is also not a perfect solution: the new skin has no hair follicles or sweat glands. Research aimed at improving the technique is ongoing.

Self-renewal and proliferation of stem cell populations is controlled, in part, by induction of apoptosis. The number of stem cells is therefore a balance between those lost to differentiation / apoptosis and those gained through proliferation. Apoptosis of stem cells is believed to be a dynamic process which changes in response to environmental conditions.

Molecular biomarkers serve as valuable tools to classify and isolate embryonic stem cells (ESCs) and to monitor their differentiation state by antibody-based techniques. ESCs can give rise to any adult cell type and thus offer enormous potential for regenerative medicine and drug discovery. A number of biomarkers, such as certain cell surface antigens, are used to assign pluripotent ESCs; however, accumulating evidence suggests that ESCs are heterogeneous in morphology, phenotype and function, thereby classified into subpopulations characterized by multiple sets of molecular biomarkers.

Histology is the scientific study of biological tissues. It is the microscopic study of the structure of biological tissues using special staining techniques combined with light and electron microscopy. Histology is the study of the microscopic structures of cells and tissues of plants and animals. 

Epigenetics is the study of genetics, cellular and physiological phenotypic trait variations that are caused by external or environmental factors that switch genes on and off and affect how cells read genes instead of being caused by changes in the DNA sequence. Epigenetic change in eukaryotic biology is the process of cellular differentiation. During morphogenesis, totipotent stem cells become the various pluripotent cell lines of the embryo, which in turn become fully differentiated cells.

Gene therapy is the therapeutic delivery of nucleic acid polymers into a patient's cells as a drug to treat disease. Gene therapy could be a way to fix a genetic problem at its source. The polymers are either expressed as proteins, interfere with protein expression, or possibly correct genetic mutations. In the future, this technique may allow doctors to treat a disorder by inserting a gene into a patient's cells instead of using drugs or surgery.

Tissue Engineering is the study of the growth of new connective tissues, or organs, from cells and a collagenous scaffold to produce a fully functional organ for implantation back into the donor host. Powerful developments in the multidisciplinary field of tissue engineering have produced a novel set of tissue replacement parts and implementation approaches. 

Computational Biology, sometimes referred to as bioinformatics, is the science of using biological data to develop algorithms and relations among various biological systems. Bioinformatics groups use computational methods to explore the molecular mechanisms underpinning stem cells. To accomplish this bioinformatics develop and apply advanced analysis techniques that make it possible to dissect complex collections of data from a wide range of technologies and sources.

The fields of stem cell biology and regenerative medicine research are fundamentally about understanding dynamic cellular processes such as development, reprogramming, repair, differentiation and the loss, acquisition or maintenance of pluripotency. In order to precisely decipher these processes at a molecular level, it is critical to identify and study key regulatory genes and transcriptional circuits. Modern high-throughput molecular profiling technologies provide a powerful approach to addressing these questions as they allow the profiling of tens of thousands of gene products in a single experiment. Whereas bioinformatics is used to interpret the information produced by such technologies. 

Somatic cell therapy is the administration to humans of autologous, allogeneic, or xenogeneic living cells which have been manipulated or processed ex vivo.

Human embryogenesis is the process of cell division and cellular differentiation of the embryo that occurs during the early stages of development. Whereas human development entails growth from a stage celled zygote to an adult human being stage. Fertilization occurs when the sperm cell successfully enters and fuses with an egg cell (ovum). The genetic material of the sperm and egg then combine to form a single cell called a zygote and the germinal stage of prenatal development commences.

Aging process is the result of the inability of various types of stem cells to continue to replenish the tissues of an organism with functional differentiated cells capable of maintaining that tissues (or organ's) original function.

‘Stem Cell Research’ is an international forum to present and discuss current perspectives in cell and stem cell research. Stem Cell Research is the unified study of the properties of cells and living organisms and all aspects of their interactions. Stem Cell Research has the goal to fulfill the prevailing gaps in the transformation of this science of hope, to serve promptly with solutions to all in the need.
