iXCells Biotechnologies provides high quality Mouse Adipose-Derived Stem Cells-brown fat (MADSC-wf), which are isolated from from C57BL/6 mouse inguinal white fat tissue or interscapular brown fat tissue. These cells are cryopreserved at P1, with >0.5 million cells in each vial and can further expand for 3-4 population doublings in Adipose-derived Stem Cell Growth Medium under the condition suggested by iXCells Biotechnologies. In vitro, mADSC can be differentiated into adipocytes and osteoblasts using Adipocyte Differentiation Medium and Osteogenic Differentiation Medium. These mADSC are negative for HIV-1, HBV, HCV, mycoplasma, bacteria, yeast, and fungi.
