Abstract (original English)
Conventional systems for isolating adipose-derived stem cells (ASC) require enzymatic digestion of adipose tissue (AT), followed by monolayer culture to the enrich the stem cell population. However, these systems are hindered by low cell yields and a lack of reproducibility. The present study was aimed at developing a unique strategy for isolating ASC based on fibrin matrix-supported three-dimensional (3-D) organ culture of native AT. Furthermore, we tried to optimize the fibrin composition by adjusting the fibrinogen and thrombin concentrations to allow rapid outgrowth and proliferation of ASC in the 3-D fibrin matrix. Human cutaneous AT fragments were encapsulated within the fibrin matrix to construct a 3-D environment and cultured under dynamic conditions. During in vitro culture the fibrin matrix provided physical support for the AT and also allowed selective outgrowth of ASC from embedded AT fragments. In situ expanded outgrown cells were recovered from the fibrin matrix by selective fibrinolysis and propagated under monolayer culture conditions. The cultured cells fulfilled the following criteria for ASC: adhesion to culture plastic, multipotent differentiation, correct immunophenotypic profile. Fibrin matrix-supported 3-D organ culture produced ASC that with high competency in terms of growth and differentiation capabilities, and resulted in a larger and more consistent
