  • The aims of this study is to isolate potential candidate breast cancer stem cell from the MCF-7 cell line to find out whether it is possible to isolate cancer stem cells using two cell surface markers: CD44 and CD24. Stem-like properties were studied in vivo by observing the tumorigenicity of different cell populations in immunosuppressed mouse models. MCF-7 cells were subculture for several passages and were sorted out into 3 different cell populations by 2 specific antibodies which bind to CD44 and CD24, using flow cytometry.

  • As populations increase and countries industrialize, the world’s demand for energy increases. Our supply of petroleum and gas is limited, but the photovoltaic cell offers a solution to the problem of a future energy shortage. This cell is already an important source of energy. In fact, it seems almost like magic. The photovoltaic cell changes sunlight directly into energy. Solar energy – energy from the sun – is clean, easily available, inexhaustible, and free, if the equipment is available....

  • Storage of putative stem/progenitor cells is also an attractive research target in tissue engineering. Collection of cells for tissue engineering is less invasive than conventional tissue or organ transplantation. However, repetitive collection of cells can stress patients. If the stem/progenitor cells could be stored, it is possible that they could be repeatedly used for future therapy, reducing the burden and the cost to patients. The concept of banking stem/progenitor cells in storage is not new. Stem/progenitor cell populations decrease in size with age (D'Ippolito et al.

  • Apoptosis in the developing nervous system results in naturally occurring cell death (NOCD), a necessary and desirable process. NOCD effectively eliminates neurons that have made faulty synapses or have not reached appropriate targets. 1 In the rest of the organism, apoptosis is essential for organogenesis, sculpts digits and extremities, and plays a role in determining polarity of structures by contributing to directional growth of cell populations. 2 Failure of carefully orchestrated and effective apoptosis in the developing fetus can have serious and long-lasting effects in the adult.

  • Hierarchy of hematopoietic differentiation. Stem cells are multipotent cells that are the source of all descendant cells and have the capacity to provide either long-term (measured in years) or short-term (measured in months) cell production. Progenitor cells have a more limited spectrum of cells they can produce and are generally a short-lived, highly proliferative population also known as transient amplifying cells. Precursor cells are cells committed to a single blood cell lineage but with a continued ability to proliferate; they do not have all the features of a fully mature cell.

  • 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 (

  • In 1996, the Committee on Population of the National Research Council sponsored a novel workshop on the biodemography of aging, which resulted in the volume Between Zeus and the Salmon: The Biodemography of Longevity (National Research Council, 1997). The workshop and its report, which considered the continuing increases in human life span in a broad biological context, launched a new phase in studies of human aging at the population level.

  • Breast cancer (BC), the most common type of cancer among women worldwide, is a polygenetic disease which is caused by the interaction of several genes. Understanding the genetic factors for early diagnosis of BC is crucial to ensure the survival of BC patients. MicroRNA 27a (miR-27a), an oncogenic miRNA, has been predicted to target on the tumor suppressor ZBTB10 that can regulate many processes of cell.

  • In order to perform biochemical and pharmacological characterization of CXCR1, we designed several CXCR1 constructs. All constructs, including a CXCR1–Gi2a fusion protein, were produced in insect cells after infection with recombinant baculovirus. The recombinant receptors exhibited specific high-affinity binding of 125 I-labelled interleukin-8, and Scatchard transformation of the binding data indicated the presence of a population of single homogenous binding sites.
