Abstract
Mesenchymal stem cells (MSCs) are currently intensively studied due to significant promise which they represent for successful implementations of future cell therapy clinical protocols. This in turn emphasizes importance of careful preclinical studies of MSC effects in various murine disease models. The appropriate cell preparations with reproducible biological properties are important to minimize variability of results of experimental cell therapies. We describe here a simple protocol for isolation of murine MSCs from adipose tissues and their reproducible multi-log expansion under hypoxia conditions.

Background
MSCs were identified initially by Friedenstein as cells in bone marrow with fibroblast-like morphology, adherence to the plastic and high self-renewal capacity resulting in formation of fibroblast-like colonies in vitro (Friedenstein et al., 1976; reviewed in Phinney and Sensebé, 2013). The MSCs, due to their potential applications in medicine, are currently one of the most intensively studied adult progenitor cell types. These cells can be isolated from various organs (Murray et al., 2014), and are thought to originate from the blood vessels, either as pericytes or as vessel wall cells. In addition to their capacity to differentiate along osteogenic, adipogenic and chondrogenic lineages, MSCs possess immunomodulating properties and are thought to participate in responses to tissue damage as well as to orchestrate anti-inflammatory reactions through their ability to influence macrophage polarization (Prockop, 2013; Caplan, 2016).
Given these properties, MSCs represent significant promise for successful implementations of future relevant cell therapy clinical protocols. This in turn emphasizes importance of careful preclinical studies with MSCs in various murine disease models. The ability to prepare large numbers of appropriate cell samples with reproducible biological properties is of vital importance for minimization of variability of results during development of MSC-based experimental cell therapies. However, unlike human MSCs that possess strong anti-oxidative defenses and thus grow fairly well under atmospheric oxygen conditions, mouse MSCs are much more sensitive to oxygen stress and have a limited lifespan and expansion capacity when cultured in conventional CO2 incubators. Culturing these cells under hypoxic conditions, on the contrary, significantly extends their lifespan and allows for multi-log expansion, providing sufficient amounts of cell material with reproducible properties for repeated experiments with murine experimental disease models (Boregowda et al., 2012; Krishnappa et al., 2013). In the present paper, we describe a simple protocol for isolation of murine MSCs from adipose tissue, their reproducible expansion under hypoxia conditions, as well as long-term storage.
