Stem cell transplantation is a procedure in which a patient receives healthy stem cells to replace damaged stem cells. There are two types of SCT: {{Autologous transplantation uses the patient's own stem cells. These cells are collected from the patient and stored for transplantation. {{Allogeneic transplantation uses stem cells from a donor .

The self-renewal ability of stem cells ensures that stem cells are not depleted and enough stem cells remain to produce sufficient number of specialized cells of that organ during the long human lifespan, until aging starts affecting stem cells. Stem cells in Regenerative Medicine and human diseases: When a disease or injury causes

associated with stem/progenitor status, such as b-catenin, NOTCH, BMI and OCT3/4. When compared to CD133 cells, the CD133 cells isolated from the HCC cell lines Box 1. Cancer stem cells (CSCs) Tissue stem cells form a small population of cells (usually much less than 1% within a given tissue), have self-renewing potential and

The concept that cancer might evolve from a small popula-tion of cells with stem cells properties was proposed about 150 years ago4,5. Huntly and Gilliland6 outlined the evolution of cancer stem cell (CSC) research from 1855. The leukemis stem cells (LSCs) were the first to be described as CSCs in human acute myeloid leukemia (AML)7.

The capacity of differentiation: Embryonic stem cells can become all cell types of the body. Adult stem cells are limited to differentiating into the cell types of their tissue of origin. 2. Grow in culture: Embryonic stem cells can be grown relatively easily in culture. Adult stem cells are rare in mature tissues, so isolating these cells from an

stem cells to form the blood cells. Therefore, two essential stem cells lines are present in the bone marrow: one that produces the blood cells (hematopoietic) and another that provides the chemical instructions for this production (BMSC). The hematopoietic stem cell produces daughter stem cells that become the source of the individual cell .

The possibility to either maintain the cells as stem/ progenitor cells or to study cell differentiation of stem/progenitor cells over time is demonstrated. Clonality is critical for stem cell research, and was accomplished in the microwell chips by isolation and clonal analysis of single mouse embryonic stem cells using flow cytometric cell .

Human stromal stem cells (also known as mesenchymal stem cells or multipotent stromal stem cells) (hMSC) are a group of clonogenic cells capable of self-renewal and multi-lineage differentiation into mesoderm-type cells e.g. osteo-blasts, adipocytes and chondrocytes [1, 2]. MSC are being introduced in a number of clinical trials for tissue .

Introduction Adipose-derived stem cells (ASCs) are mul-tipotent mesenchymal stem cells (MSCs) whose differentiation potential is similar to that of other MSCs1. They exhibit definitive stem cell char-

a presence of stem-like cancer cells within Rb tumors [17]. Our group provided evidence of putative stem-like cells in primary Rb tumor cells using a bi-parameter model by flow cytometry with a phenotype of low CD133, high CD44 expression and small sized cells (FSClo/SSClo/ CD133lo/CD44hi) expressing progenitor cell markers (PROX1 and SYX1A) [18].

organism that renew tissue (e.g., hematopoietic stem cells, a type of cell found in the blood), the most funda-mental and extraordinary of the stem cells are found in the early stage embryo. These embryonic stem (ES) cells, unlike the more differentiated adult stem cells or other cell types, retain the special ability to develop into nearly

Stem Cells Stem cells remain a mystery to most people, even though the debate over stem cell research, treatments, ethics, and funding has led to legal, legislative, scientific, religious, and policy debates. This publication offers a general overview of stem cells—their sources, practical uses and potential, and ethical problems.

the adult organism. Stem /progenitor cells are defined by their ability to self-renew and their capacity to differentiate into specialized cell types. Toti- and pluripotent stem cells can give rise to any mature cell type, whereas multipotent stem/progenitor cells can differentiate into cells of a closely related cell family, e.g. epithelial cells.

applications of engineered stem cells have primarily focused on regenerative medicine. In particular, studies have concen-trated on engineering stem cells for the regeneration of cardiac, neural, and orthopedic tissues. [ 3,10 ] For instance, engineered neural stem cells (NSCs) can be transplanted following central

various cell lineages. They can be classified into embryonic stem cells (ESC) and non-embryonic stem cells (non-ESC). Mesenchymal stem cells (MSC) show great promise in several animal studies and clinical trials. ESCs have a great potential but their use is still limited due to ethical and scientific considerations.

niche can be colonized by autologous stem cells derived from other tissues. In some areas of medicine, autologous stem cells are already used in clinical practice for the repair of damaged tissues and organs, although these methods are still experimental [21,22]. There were several publications about the use of stem cells for improving the

Human pluripotent embryonic stem cells have two special features: self-renewal and pluripotency. It is important to understand the properties of pluripotent stem cells and reprogrammed stem cells. One of the major problems is the risk of reprogrammed stem cells developing into tumors. To understand the process of differentiation through

Since the regulation of gap junctions is lost in colorectal cancer cells, the goal of this study is to determine the effect of GJIC restoration in colorectal cancer cells. Overexpression of connexin 43 (Cx43) in SW480 colorectal cancer cells causes a 6-fold increase of gap junction activity compared to control un-transfected cells. This

Characteristics of Stem Cells Stem cells are defined by their two unique characteristics: the ability to remain undifferen-tiated and their level of potency. An undifferentiated cell is a cell that has not developed into a specific cell type, such as a neuron or a red blood cell, and is capable of self-renewal. Stem cells

with NCCs being primarily a progenitor cell population as opposed to a true stem cell population in the strictest sense. The true stem cells may well be the neural stem cells (NSCs) that constitute the neural ectoderm from which NCCs are ultimately derived as suggested from single neuroepithelial cell in vivo labeling experiments.

macrophages and monocytes. Bone marrow (BM)-resident mesenchymal stem cells (MSCs) can give rise to osteoblasts, chondrocytes, adipocytes and reticular stroma 1. Self-renewal Stem cells also possess the capacity of self-renewal; that is, the ability to undergo numerous cell divisions while retaining their stem cell identity.

How are organisms organized? Many-celled organisms are organized in cells, tissues, organs, and organ systems. Cells: Animals and plants are many-celled organisms. Animals are made up of many kinds of cells. You are made of blood cells, bone cells, skin cells, and many others. A plant also has different cells in its roots, stems, and leaves.
