Characteristics of the cancer stem cell niche and therapeutic strategies
Stem cell research & therapeutics, 2022 Distinct regions harboring cancer stem cells (CSCs) have been identified within the microenvironment of various tumors, and as in the case of their healthy counterparts, these anatomical regions are termed “niche.” Thus far, a large volume of studies ...

Hepatic stem cell niches [PDF]
Journal of Clinical Investigation, 2013 Stem cell niches are special microenvironments that maintain stem cells and control their behavior to ensure tissue homeostasis and regeneration throughout life. The liver has a high regenerative capacity that involves stem/progenitor cells when the proliferation of hepatocytes is impaired.

KAI1(CD82) is a key molecule to control angiogenesis and switch angiogenic milieu to quiescent state
Journal of Hematology & Oncology, 2021 Background Little is known about endogenous inhibitors of angiogenic growth factors. In this study, we identified a novel endogenous anti-angiogenic factor expressed in pericytes and clarified its underlying mechanism and clinical significance.

Artificial Stem Cell Niches [PDF]
Advanced Materials, 2009 AbstractStem cells are characterized by their dual ability to reproduce themselves (self‐renew) and specialize (differentiate), yielding a plethora of daughter cells that maintain and regenerate tissues. In contrast to their embryonic counterparts, adult stem cells retain their unique functions only if they are in intimate contact with an instructive ...

Stem Cell Niche Microenvironment: Review [PDF]
Bioengineering, 2021 The cornea comprises a pool of self-regenerating epithelial cells that are crucial to preserving clarity and visibility. Limbal epithelial stem cells (LESCs), which live in a specialized stem cell niche (SCN), are crucial for the survival of the human corneal epithelium.

The Vascular Stem Cell Niche [PDF]
Journal of Cardiovascular Translational Research, 2012 Stem cells in adult organs reside in specialized niches that regulate their proliferation and differentiation. Investigations during the last few years have unveiled a regulatory role for blood vessels in these microenvironments. Mesenchymal stem cells (MSCs) are located surrounding capillaries in a variety of tissues and have the capacity to ...
