Data on isolating mesenchymal stromal cells from human adipose tissue using a collagenase-free method

Abstract

The present dataset describes a detailed protocol to isolate mesenchymal cells from human fat without the use of collagenase. Human fat specimen, surgically cleaned from non-fat tissues (e.g., blood vessels) and reduced into smaller fat pieces of around 1–3 mm size, is incubated in complete culture media for five to seven days. Then, cells started to spread out from the fat explants and to grow in cultures according to an exponential pattern. Our data showed that primary mesenchymal cells presenting heterogeneous morphology start to acquire more homogenous fibroblastic-like shape when cultured for longer duration or when subcultured into new flasks. Cell isolation efficiency as well as cell doubling time were also calculated throughout the culturing experimentations and illustrated in a separate figure thereafter. This paper contains data previously considered as an alternative protocol to isolate adipose-derived mesenchymal stem cell published in “Proliferation and differentiation of human adipose-derived mesenchymal stem cells (ASCs) into osteoblastic lineage are passage dependent” [1].
