Human stem cells

After the first edition published in 2007 that became a best seller, the continuous scientific developments in the field have prompted us to produce the second edition of this book. As it happens in life and science, some of the novel and promising data presented in the first edition have been confirmed, some not, and new breakthrough achievements have been accomplished. Stem Cells in Reproductive Medicine, Basic Science and Therapeutic Potential, second edition, updates the revolutionary advances in stem cell science that may potentially impact on human reproductive medicine.

Stem cell research has the potential to affect the lives of millions of people in the United States and around the world. This research is now regularly front-page news because of the controversy surrounding the derivation of stem cells from human embryos. Realizing the promise of stem cells for yielding new medical therapies will require us to grapple with more than just scientific uncertainties. The stem cell debate has led scientists and nonscientists alike to contemplate profound issues, such as who we are and what makes us human beings.

We are pleased to offer our committee’s report on guidelines for human embryonic stem cell research. This report and its recommendations are the result of many hours of committee meetings as well as a public workshop. During those sessions we heard from many dedicated and talented people who represent a wide range of views. We have tried to take these diverse perspectives into account in a report that mirrors the seriousness with which we have reflected upon them.

Twenty years after the discovery of neural stem cells, the question whether the central nervous system can be considered among regenerative tissues is still open. On one side, deep characterization of neural stem and progenitor cells, their niches, and their progeny in brain neurogenic sites overtly showed that new neurons can be generated in the brain of adult mammals, including humans.

The ability of Ngoclinh ginseng (NLG) stem cell extract in controlling the skin aging process in human fibroblasts was investigated. To evaluate the cosmeceutical effects of the extracts on the aging process, MTT assays were conducted with various concentrations of NLG stem cells. No extracts showed any cytotoxic activities on fibroblasts at concentrations of up to 10 mg/ml.

Since stem cells were first isolated from a human embryo in 1998, interest in the development of a global stem cell market has grown exponentially. Prior to this, while the existence of human embryonic stem cells had long been established, it was thought impossible to isolate them with any degree of success. The 1998 discovery opened up a new avenue of research that subsequently became one of the world’s hottest topics.

The specific features of the plasticity of adult stem cells are largely unknown. Recently, we demonstrated the hepatic differentiation of human adipose tissue-derived mesenchymal stem cells (AT-MSCs). To identify the genes responsible for hepatic differentiation, we examined the gene expres-sion profiles of AT-MSC-derived hepatocytes (AT-MSC-Hepa) using several microarray methods.

Therefore, ex vivo expansion of BMSCs is required to obtain a sufficient number of transplantable cells. Since BMSCs require several kinds of supportive factors for their growth, it is standard practice to use fetal bovine serum (FBS), while autologous human serum (HS) and pooled allogeneic HS have also been used. It has been suggested that FBS may not be favorable for clinical applications due to the possible risk of contamination (prions, viruses, zoonosis) or immunological reactions against xenogeneic serum antigens (Agata et al., 2009).

Human embryonic stem cell (hESC) lines, like those from other species, are pluripotent cell lines derived from the inner cell mass (ICM) of the developing embryo. Due to their exceptional capability of proliferating indefi nitely as undifferentiated cells when cultured in appropriate conditions, and of sustaining a normal karyotype, hESCs may have broad applications for industrial uses; clinical purposes, namely, cell-based therapy; and research of early human development, differentiation mechanisms, and lineage commitment.

New Concepts in the Development of Cancer Therapeutics Cancer Stem Cells It has long been recognized that only a small proportion of the cells within a tumor are capable of initiating colonies in vitro or of forming tumors at high efficiency when injected into immunocompromised NOD/SCID mice. Current work indicates that human acute and chronic myeloid leukemias (AML and CML) have a small population of cells (

Graft Failure While complete and sustained engraftment is usually seen posttransplant, occasionally marrow function either does not return or, after a brief period of engraftment, is lost. Graft failure after autologous transplantation can be the result of inadequate numbers of stem cells being transplanted, damage during ex vivo treatment or storage, or exposure of the patient to myelotoxic agents posttransplant. Infections with cytomegalovirus (CMV) or human herpes virus type 6 have also been associated with loss of marrow function.
