Abstract
Abstract:
Hematopoietic stem cells (HSCs) have a self-renewal as well as pluripotency properties and are responsible to produce all types of blood cells. These cells are generated during embryonic development and transit through various anatomical niches (bone marrow microenvironment). Today, they are easily enriched from some sources including peripheral blood, bone marrow, and umbilical cord blood (UCB). HSCs have been used for many years to treat a variety of cancers and blood disorders such as various types of leukemia, lymphoma, myelodysplastic, myeloproliferative syndromes etc. Although almost 50 years have passed since the discovery of stem cells and many investigations have been done on cell therapy and regenerative medicine, further studies need to be conducted in this regard. This manuscript review the history, location, evolution, isolation, and therapeutic approaches of HSCs.

Abstract
Human adult stem cells (hASCs) have become an attractive source for autologous cell transplantation, tissue engineering, developmental biology, and the generation of human-based alternative in vitro models. Among the 3 germ cell layers, the mesoderm is the origin of today's most widely used and characterized hASC populations. A variety of isolated nonhematopoietic mesoderm-derived stem cell populations exist, and all of them show important differences in terms of function, efficacy, and differentiation potential both in vivo and in vitro. To better understand whether the intrinsic properties of these cells contribute to the overall differentiation potential of hASCs, we compared the global gene expression profiles of 4 mesoderm-derived stem cell populations: human adipose tissue-derived stromal cells, human bone marrow-derived stromal cells (hBMSCs), human (fore)skin-derived precursor cells (hSKPs), and human Wharton's jelly-derived mesenchymal stem cells (hWJs). Significant differences in gene expression profiles were detected between distinct stem cell types. hSKPs predominantly expressed genes involved in neurogenesis, skin, and bone development, whereas hWJs and, to some extent, hBMSCs showed an increased expression of genes involved in cardiovascular and liver development. Interestingly, the observed differential gene expression of distinct hASCs could be linked to existing differentiation data in which hASCs were differentiated toward specific cell types. As such, our data suggest that the intrinsic gene expression of the undifferentiated stem cells has an important impact on their overall differentiation potential as well as their application in stem cell-based research. Yet, the factors that define these intrinsic properties remain to be determined.

Abstract
Recently, evidence has been provided that mesenchymal stem/progenitor cells (MSC) from various sources (bone marrow, adipose tissue, skin, placenta, umbilical cord) could occasionally overcome lineage borders and differentiate into endodermal (hepatocytes) and ectodermal (neural cells) cell types in vitro. Whereas unidirectional differentiation into other mesenchymal cell types, including adipocytes, chondrocytes, and osteoblasts, readily occurs in the presence of a simple cocktail of growth factors and nutrients, successful bypassing of lineage borders mainly depends on multistep processes in a coordinated signaling network. Here, we provide a reproducible basic methodology to differentiate adult MSC into functional hepatocytes in a sequential and time-dependent way. In addition, focus lies on the functional characterization of MSC-derived hepatocyte-like cells. In particular, we provide a detailed modus operandi to measure the inducible cytochrome P450 (CYP)-dependent activity of MSC-derived hepatocyte-like cells.

Abstract
The use of neuroprotective therapies begs the question of how such therapies could affect preexisting stem cell populations within the host, as well as those introduced through cell-replacement therapy. Multiple mechanisms may mediate stem cell responses to neuroprotectants such as host/donor age and gender, cellular lineage/differentiation status, and mitochondrial dynamics. Current therapeutic sources for stem cells are embryonic, somatic, or induced pluripotent, with very little known about the effects of gender, age, cell type, and mitochondrial dynamics. With the advent of therapies to stimulate and recruit endogenous stem cells or transplant donor cells into damage areas in the hopes of recuperative regeneration of lost neurons, it is important to discuss mechanisms that dictate the winning players in the neuroprotection game. This review will focus on our current understanding of the characteristics of renewing stem cells that may affect neuroprotection.

The beliefs, myths, and reality surrounding the word hema (blood) from homer to the present. Anemia 2010; 2010:857657.

Abstract
All ancient nations hinged their beliefs about hema (blood) on their religious dogmas as related to mythology or the origins of religion. The Hellenes (Greeks) especially have always known hema as the well-known red fluid of the human body. Greek scientific considerations about blood date from Homeric times. The ancient Greeks considered hema as synonymous with life. In Greek myths and historical works, one finds the first references to the uninterrupted vascular circulation of blood, the differences between venous and arterial blood, and the bone marrow as the site of blood production. The Greeks also speculated about mechanisms of blood coagulation and the use of blood transfusion to save life.

Abstract
Stem cells are a unique source of self-renewing cells within the human body. Before the end of the last millennium, adult stem cells, in contrast to their embryonic counterparts, were considered to be lineage-restricted cells or incapable of crossing lineage boundaries. However, the unique breakthrough of muscle and liver regeneration by adult bone marrow stem cells at the end of the 1990s ended this long-standing paradigm. Since then, the number of articles reporting the existence of multipotent stem cells in skin, neuronal tissue, adipose tissue, and bone marrow has escalated, giving rise, both in vivo and in vitro, to cell types other than their tissue of origin. The phenomenon of fate reprogrammation and phenotypic diversification remains, though, an enigmatic and rare process. Understanding how to control both proliferation and differentiation of stem cells and their progeny is a challenge in many fields, going from preclinical drug discovery and development to clinical therapy. In this review, we focus on current strategies to differentiate embryonic, mesenchymal(-like), and liver stem/progenitor cells into hepatocytes in vitro. Special attention is paid to intracellular and extracellular signaling, genetic modification, and cell-cell and cell-matrix interactions. In addition, some recommendations are proposed to standardize, optimize, and enrich the in vitro production of hepatocyte-like cells out of stem/progenitor cells.

Abstract
Third trimester amniotic fluid (AF)-derived human mesenchymal stem cells (MSCs) can be greatly expanded in vitro and induced to differentiate into multiple mesenchymal cell types. This study aimed to investigate the biological characteristics of MSCs from third trimester AF as a new source of therapeutic stem cells. Forty third trimester AF samples were obtained from healthy women who underwent elective caesarean section for breech presentation. A simple culture protocol for MSCs was used. A cell growth curve was drawn, and cell surface antigens and cytokines were analysed by immunofluorescent staining, reverse transcription-polymerase chain reaction and flow cytometry. MSCs from third-trimester AF were successfully isolated, cultured and enriched. MSCs expanded extensively without feeders, they were not tumourigenic and were induced to differentiate into osteocytes. Surface antigens were analysed and found to express the pluripotency marker Oct-4. Considering the great feasibility of biomedical engineering using MSCs, third trimester AF may provide a rich source for investigation of human MSCs.

Abstract
Planarians are a model system for studying adult stem cells, as they possess the neoblasts, a population of pluripotent adult stem cells able to give rise to both somatic and germ cells. Although over the last years several efforts have been made to shed light on neoblast biology, only recent evidence indicate that this population of cells is heterogeneous. In this study we irradiated planarians with different non-lethal X-ray doses (1-5 Gy) and we identified subpopulations of neoblasts with diverse levels of tolerance to X-rays. We demonstrated that a dramatic reduction of neoblasts occurred soon after non-lethal irradiations and that de-novo proliferation of some radioresistant cells re-established the primary neoblast number. In particular, a strong proliferation activity occurred at the ventral side of irradiated animals close to the nervous system. The produced cells migrated towards the dorsal parenchyma and, together with some dorsal radioresistant cells, reconstituted the entire neoblast population demonstrating the extreme plasticity of this adult stem cell system.
