Distribution of interstitial stem cells in Hydra [PDF]
The distribution of interstitial stem cells along the Hydra body column was determined using a simplified cloning assay. The assay measures stem cells as clone-forming units (CFU) in aggregates of nitrogen mustard inactivated Hydra tissue.

Cell cycle length, cell size, and proliferation rate in hydra stem cells [PDF]
We have analyzed the cell cycle parameters of interstitial cells in Hydra oligactis. Three subpopulations of cells with short, medium, and long cell cycles were identified. Short-cycle cells are stem cells; medium-cycle cells are precursors to nematocyte

Stem cells, cancer, and cancer stem cells [PDF]
Stem cell biology has come of age. Unequivocal proof that stem cells exist in the haematopoietic system has given way to the prospective isolation of several tissue-specific stem and progenitor cells, the initial delineation of their properties and expressed genetic programmes, and the beginnings of their utility in regenerative medicine.

Forces in stem cells and cancer stem cells
Endogenous and exogenous forces are critical in physiology and pathology of the human body. Increasing evidence suggests that these forces, mechanics, and force-associated signaling are essential in regulating functions of living cells. Here we review advances in understanding the impact of forces and mechanics on functions and fate of embryonic stem ...

Proliferation versus Differentiation: Redefining Retinoic Acids Role. [PDF]
Retinoic acid is commonly used in culture to differentiate stem cells into neurons and has established neural differentiation functions in vivo in developing and adult organisms. In this issue of Stem Cell Reports, Mishra et al.

PTEN, Stem Cells, and Cancer Stem Cells [PDF]
Like normal stem cells, "cancer stem cells" have the capacity for indefinite proliferation and generation of new cancerous tissues through self-renewal and differentiation. Among the major intracellular signaling pathways, WNT, SHH, and NOTCH are known to be important in regulating normal stem cell activities, and their alterations are associated with ...

The cargo protein MAP17 (PDZK1IP1) regulates the cancer stem cell pool activating the Notch pathway by abducting NUMB [PDF]
Purpose: Cancer stem cells (CSC) are self-renewing tumor cells, with the ability to generate diverse differentiated tumor cell subpopulations. They differ from normal stem cells in the deregulation of the mechanisms that normally control stem cell ...

Prostate Stem Cells and Cancer Stem Cells [PDF]
Stem/progenitor cells play central roles in processes of organogenesis and tissue maintenance, whereas cancer stem cells (CSCs) are thought to drive tumor malignancy. Here, we review recent progress in the identification and analysis of normal prostate stem/progenitor cells as well as putative CSCs in both genetically engineered mouse models as well as

Transient PP2A inhibition alleviates normal tissue stem cell susceptibility to cell death during radiotherapy [PDF]
Unintended outcomes of cancer therapy include ionizing radiation (IR)-induced stem cell depletion, diminished regenerative capacity, and accelerated aging.
