Abstract (original English)
Adipose tissue has become a promising source of adult stem cells. Looking for optimal culture conditions, we evaluated the ability of L15, a free-gas exchange culture medium, to support cell proliferation and adipogenesis of murine 3T3-F442A and human normal (HNPA) and lipoma-derived (HLPA) pre-adipocytes. 3T3-F442A, HNPA and HLPA cell proliferation were compared in short-term cultures and along multiple passages in Dulbecco's modified Eagle medium (DMEM) or DMEM-F12 under a 5% CO(2) atmosphere or L15 medium under a free-gas exchange atmosphere. Adipogenesis in these cells was evaluated by quantifying lipid accumulation and glycerol-3-phosphate dehydrogenase (GPDH) activity, and by assaying the expression of adipogenic markers by reverse transcriptase-polymerase chain reaction (RT-PCR). 3T3 pre-adipocytes grew at similar rates in serum-supplemented L15 or DMEM, but L15 induced higher colony-forming efficiency in these cells. HNPA and HLPA grew more actively in L15 than in DMEM-F12 for more than 10 successive passages and reached higher colony-forming efficiency in L15 medium. On the other hand, while high-glucose DMEM and L15 supplemented with glucose 1 g/L induced similar levels of 3T3 adipogenesis, L15 with no added glucose increased HNPA and HLPA adipogenesis with respect to DMEM-F12, as measured by lipid accumulation, GPDH activity and expression of adipogenic markers C/EBP
