: Stem cells are undifferentiated cells with self-renewal property with varying differentiation potential that allow the regeneration of tissue cells of an organism throughout adult life beginning with embryonic development. Through the asymmetric cell divisions, each stem cell replicates itself and produces an offspring identical with the mother cell, and a daughter cell that posses the characteristics of a progenitor cell and commits to a specific lineage to differentiate into tissue cells to maintain homeostasis. To maintain a pool of stem cells to ensure tissue regeneration and homeostasis, it is important to regulate the metabolic functioning of stem cells, progenitor cells and adult tissue stem cells that will meet their internal and external needs. Upon fertilization, the zygote transforms metabolic reprogramming while implantation, embryonic development, organogenesis processes and after birth through adult life. Metabolism in stem cells is a concept that is relatively new to be enlightened. There are no adequate and comprehensives in vitro studies on the comparative analysis of the effects of one-carbon (1-C) metabolism on fetal and adult stem cells compared to embryonic and cancer stem cells’ studies that have been reported recently Since 1-C metabolism is linking parental environmental/dietary factors and fetal development, investigating the epigenetic, genetic, metabolic and developmental effects on adult period is necessary. Several mutations and abnormalities in 1-C metabolism noted in disease changing from diabetes, cancer, pregnancyrelated outcomes such as pre-eclampsia, spontaneous abortion, placental abruption, premature delivery, cardiovascular diseases. In this review, the effects of 1-C metabolism, mainly the methionine and folate metabolism, in stem cells that exist in different developmental stages will be discussed.

Stem cells are characterized by their capability to self-renew and terminally differentiate into multiple cell types. Somatic or adult stem cells have a finite self-renewal capacity and are lineage-restricted. The use of adult stem cells for therapeutic purposes has been a topic of recent interest given the ethical considerations associated with embryonic stem (ES) cells. Mesenchymal stem cells (MSCs) are adult stem cells that can differentiate into osteogenic, adipogenic, chondrogenic, or myogenic lineages. Owing to their ease of isolation and unique characteristics, MSCs have been widely regarded as potential candidates for tissue engineering and repair. While various signaling molecules important to MSC differentiation have been identified, our complete understanding of this process is lacking. Recent investigations focused on the role of epigenetic regulation in lineage-specific differentiation of MSCs have shown that unique patterns of DNA methylation and histone modifications play an important role in the induction of MSC differentiation toward specific lineages. Nevertheless, MSC epigenetic profiles reflect a more restricted differentiation potential as compared to ES cells. Here we review the effect of epigenetic modifications on MSC multipotency and differentiation, with a focus on osteogenic and adipogenic differentiation. We also highlight clinical applications of MSC epigenetics and nuclear reprogramming.

Advantages And Disadvantages

First discovered by Friedenstein in 1976, mesenchymal stem cells (MSCs) are adult stem cells found throughout the body that share a fixed set of characteristics. Discovered initially in the bone marrow, this cell source is considered the gold standard for clinical research, although various other sources—including adipose tissue, dental pulp, mobilised peripheral blood and birth-derived tissues—have since been identified. Although similar, MSCs derived from different sources possess distinct characteristics, advantages and disadvantages, including their differentiation potential and proliferation capacity, which influence their applicability. Hence, they may be used for specific clinical applications in the fields of regenerative medicine and tissue engineering. This review article summarises current knowledge regarding the various sources, characteristics and therapeutic applications of MSCs.Keywords: Mesenchymal Stem Cells; Adult Stem Cells; Regenerative Medicine; Cell Differentiation; Tissue Engineering.

Essential Components

Regenerative medicine is an alternative solution for organ transplantation. Stem cells and nanoscaffolds are two essential components in regenerative medicine. Mesenchymal stem cells (MSCs) are considered as primary adult stem cells with high proliferation capacity, wide differentiation potential, and immunosuppression properties which make them unique for regenerative medicine and cell therapy. Scaffolds are engineered nanofibers that provide suitable microenvironment for cell signalling which has a great influence on cell proliferation, differentiation, and biology. Recently, application of scaffolds and MSCs is being utilized in obtaining more homogenous population of MSCs with higher cell proliferation rate and greater differentiation potential, which are crucial factors in regenerative medicine. In this review, the definition, biology, source, characterization, and isolation of MSCs and current report of application of nanofibers in regenerative medicine in different lesions are discussed.

Mesenchymal stem cells (MSC) are adult stem cells with fibroblast-like morphology, which can be easily isolated from bone marrow and expanded in culture. Mesenchymal stem cells are able to grow from a single cell into a cell clone, which makes them potentially useful for gene targeting. In our recent study we investigated the dynamics of epigenetic reprogramming following nuclear transfer (NT) with MSC and found that these cells can support development of cloned embryos as good as genetically identical fibroblasts (Brero et al. 2009 Cloning Stem Cells 11, 319-329). In the present study we tested whether live cloned rabbits can be produced from MSC. Nuclear donor cells were isolated from a 6-week-old transgenic Ali/Bas rabbit, expanded in culture, and assessed for their differentiation potential. Mesenchymal stem cells were transfected with a green fluorescent protein (GFP) reporter gene construct and stable cell clones were selected (GFP-MSC). The MSC and GFP-MSC were used for NT at passage 3 to 7 after serum starvation for 2 to 4 days. Nuclear transfer was performed essentially as described previously (Yang et al. 2007 Reproduction 133, 219-320). To assess the development to blastocyst, reconstructed embryos were cultured in B2 medium for 5 to 6 days, whereas for in vivo development embryos were cultured only overnight and then transferred into recipients at the 4- to 8-cell stage. In the MSC group, 844 oocytes were used, 793 (94%) of them fused, 698/786 (89%) cleaved, and 48/128 (38%) developed to blastocyst. After transfer of 483 cloned embryos into 13 recipients, 2 from 8 pregnant recipients gave birth to 10 (2.4%) rabbits, from which 2 and 1 survived for more than 7 days and 3 months, respectively. In the GFP-MSC group, 444 oocytes were used, 412 (93%) of them fused, 377/409 (92%) cleaved, and 97/178 (55%) developed to blastocyst. Transfer of 216 cloned embryos into 8 recipients resulted in 4 pregnancies. One recipient gave birth to 6 (3.7%) live and 2 stillborn rabbits, from which 2 and 1 rabbits survived for more than 3 days and 2 weeks, respectively. All cloned rabbits carried a GFP gene, and green fluorescence could be detected in the follicles of the skin under a fluorescence microscope (Zeiss Axiovert200, Carl Zeiss, Germany). Our study demonstrates that live cloned rabbits can be produced from genetically modified MSC, thus paving the way to generate gene targeted animals. This work is supported by Roche Diagnostic GmbH.

Ectomesenchymal stem cells (EMSCs) are typical adult stem cells obtained from the cranial neural crest. They have the potential to differentiate into various cell types, such as osseous cells, neurons and glial cells. Three-dimensional (3 D) printing is a novel method to construct biological structures by rapid prototyping. Previously, our group reported on the stemness and multi-lineage differentiation potential of EMSCs on gels. However, the exploration of EMSCs in 3 D printing and then evaluation of the growth and neuronal differentiation of EMSCs on extruded 3 D printable hybrid hydrogels has not been reported. Therefore, the current study explored the novel hybrid Sodium alginate-Matrigel (SA-MA) hydrogel extruded 3 D printing to design an in vitro scaffold to promote the differentiation and growth of EMSCs. In addition, the physical properties of the hydrogel were characterized and its drug-releasing property determined. Notably, the results showed that the construct exhibited a sustain-released effect of growth factor BDNF in accordance with the Higuchi equation. Moreover, the cell survival rate on the 3 D printed scaffold was 88.22 ± 1.13% with higher neuronal differentiation efficiency compared with 2 D culture. Thus, SA-MA’s ability to enhanced EMSCs neuronal differentiation offers a new biomaterial for neurons regeneration in the treatment of spinal cord injury.

AbstractFor reasons that are not apparent, it has been difficult to isolate and expand the adult stem cells referred to as mesenchymal stem cells or marrow stromal cells (MSCs) from murine bone marrow. We developed a protocol that provides rapidly expanding MSCs from 5 strains of inbred mice. The MSCs obtained from 5 different strains of mice were similar to human and rat MSCs in that they expanded more rapidly if plated at very low density, formed single-cell–derived colonies, and readily differentiated into either adipocytes, chondrocytes, or mineralizing cells. However, the cells from the 5 strains differed in their media requirements for optimal growth, rates of propagation, and presence of the surface epitopes CD34, stem cell antigen-1 (Sca-1), and vascular cell adhesion molecule 1 (VCAM-1). The protocol should make it possible to undertake a large number of experiments with MSCs in transgenic mice that have previously not been possible. The differences among MSCs from different strains may explain some of the conflicting data recently published on the engraftment of mouse MSCs or other bone marrow cells into nonhematopoietic tissues.

Abstract Notch is a well-conserved signaling pathway and its function in cell fate determination is crucial in embryonic development and in the maintenance of tissue homeostasis during adult life. Notch activation depends on cell-cell interactions that are essential for the generation of cell diversity from initially equivalent cell populations. In the adult hematopoiesis, Notch is undoubtedly a very efficient promoter of T-cell differentiation, and this has masked for a long time the effects of Notch on other blood lineages, which are gradually being identified. However, the adult hematopoietic stem cell (HSC) remains mostly refractory to Notch intervention in experimental systems. In contrast, Notch is essential for the generation of the HSCs, which takes place during embryonic development. This review summarizes the knowledge accumulated in recent years regarding the role of the Notch pathway in the different stages of HSC ontology from embryonic life to fetal and adult bone marrow stem cells. In addition, we briefly examine other systems where Notch regulates specific stem cell capacities, in an attempt to understand how Notch functions in stem cell biology.
