Hypoxia and adipose-derived stem cell-based tissue regeneration and engineering

Expert Opin Biol Ther. 2011 Jun;11(6):775-86. doi: 10.1517/14712598.2011.570258. Epub 2011 Mar 18.

Abstract

Introduction: Realization that oxygen is one of the key regulators of development and differentiation has a profound significance on how current cell-based and tissue engineering applications using adipose-derived stem cells (ASCs) can be further improved.

Areas covered: The article provides an overview of mechanisms of hypoxic responses during physiological adaptations and development. Furthermore, a synopsis of the hypoxic responses of ASCs is provided, and this information is presented in context of their utility as a major source of stem cells across the regenerative applications explored to date.

Expert opinion: The reader will obtain insight into a highly specific area of stem cell research focusing on ASCs and hypoxia. In order to enhance the level of comprehension, a broader context with other stem cell and experimental systems is provided. It is emphasized that the pericellular oxygen tension is a critical regulatory factor that should be taken into account when devising novel stem cell-based therapeutic applications along with other parameters, such as biochemical soluble factors and the growth substrates.
