This chapter illustrates the usefulness of capillary electrophoresis (CE) for the detection of gene mutation, i.e., point mutation, methylation, and microsatellite analysis. In order to provide a general description of the main results and challenges in the field, some relevant appli ...

Urinary 8-hydroxy-2′-deoxyguanosine (8OHdG) is an excellent marker of oxidative DNA damage. Until now, urinary 8OHdG has been measured by high-performance liquid chromatography with electrochemical detection. A simple and sensitive method for the analysis of urinary 8OHdG by ca ...

Capillary electrophoresis (CE) is an efficient tool for amino acid (AA) analysis. However, its role can be fully accounted for only by examining the applications on real matrices. Methods must be successfully transferred into working environments for use by non-CE experts before their pow ...

Peptides are an important class of analytes in chemistry, biochemistry, and food chemistry as well as medical and pharmaceutical sciences. As a high-resolution technique, capillary electrophoresis (CE) is well suited for the analysis of polar compounds such as peptides. In addition, CE is ...

Capillary Electrophoresis (CE) has become an accepted method for the separation of inorganic and organic ions. Usually, direct and indirect optical detection methods are used in conventional CE. However, with contactless conductivity detection, much better detection limits in the ...

This chapter describes the basic principles of protein analysis by capillary electrophoresis, and provides an overview of the literature and thus a comprehensive summary of special topics in this field. The “Materials and Methods” section includes the main experimental points to be ta ...

Capillary electrophoresis (CE) is a very efficient tool for separating and characterizing synthetic polymers, copolymers, and polyelectrolytes. Different modes of CE (free solution capillary electrophoresis , entangled polymer solution CE , capillary gel electrophores ...

Umbilical cord blood (UCB) is gaining more prominence in recent times as a source of non-embryonic multipotent stem cells. Global annual human birth rate (100 million) presents UCB as the largest non-controversial stem cell source, with an added advantage of naive immune status. Cord blood st ...

Human cord blood (CB), collected from the postpartum placenta and umbilical cord, has been identified as a rich source of hematopoietic stem cells (HSCs) and provides an alternative to bone marrow or mobilized peripheral blood transplantation. However, the major restriction of CB transp ...

Hematopoiesis is the process by which stem cells divide and differentiate to produce the multiple types of mature cells found in blood. The process begins in early embryonic development and continues throughout adult life, primarily in the bone marrow. Various in vivo and in vitro assays have b ...

In organ transplantation, major efforts are currently developed to minimize or even to withdraw immunosuppressive drugs. Different protocols have therefore been proposed to induce graft tolerance, that is, the survival of an allograft in the absence of continuing immunosuppress ...

Mesenchymal stem cells (MSCs) are multipotent progenitor cells isolated by various relatively easily accessible tissues, such as bone marrow and cord blood. MSCs gained attention because of their ease for in vitro expansion together with their multilineage potential. More recentl ...

Intact or genetically manipulated mesnechymal stem cells (MSCs) are being considered an important cell source for developing human cell-based therapeutic approaches. For applications in which transient, high-level expression of the transgene is necessary, adenovirus vect ...

Mesenchymal stem cells or marrow stromal cells (MSCs) represent a multipotent adult cellular population with immunomodulatory functions. In the adult human body, they are present in various niches, but their main source is bone marrow (BM). The regeneration capability of MSCs, their ease ...

Embryonic stem cells represent a pluripotent population of cells capable of self-renewal, large-scale expansion, and differentiation in various cell lineages including cells of hematopoietic lineage. In this chapter, we describe a three-step cell culture method for directed di ...

Human embryonic stem cells (hESC) have the potential to treat a wide range of diseases. Currently, the use of existing hESC lines in human clinical applications is limited, as they are derived from blastocysts subjected to immunosurgery with animal derived antibodies, and are maintained on m ...

The main objective of cell bioengineering is to generate customized tissues that allow recovering the lost functions in the organism in the absence of immune rejection. Although the possibility of in vitro generation of entire organs is technically very complex, obtaining specific cell ...

In this chapter, we introduce a co-culture protocol for human embryonic stem (hES) cell differentiation in which opamine (DA) neurons with midbrain-specific markers are efficiently derived. Human ES cells on a feeder layer of stromal cells are induced to differentiate into neuroepithe ...

The central nervous system (CNS) is composed of multiple cell types formed through a process of lineage commitment and phenotypic differentiation of stem-like progenitor cells into three key cell types: neurons, astrocytes, and oligodendrocytes. The ability to isolate and culture th ...

The clinical goal of tissue engineering is to restore, repair, or replace damaged tissues in the body. Significant advances have been made in recent years using stem cells as a cell source for cartilage tissue engineering and reconstructive surgery applications. Embryonic stem cells have d ...
