To present an experimental model of qualitative and quantitative analysis of mesenchymal stem cells from fat of rabbits obtained by lipectomy. The fat could be a great source for obtaining mesenchymal stem cells and to create conditions for repairing injured tissues by bioengineering.
New Zealand rabbits (n = 10) adipose panicle (2-3 cm) were removed by lipectomy, fragmented and washed with PBS and enzymatically dissociated with trypsin/EDTA. Lately, these cells were incubated in culture medium DMEM and after 20 days, was performed quantitative analysis of the accession of first and second mesenchymal cells in cell culture bottles.
The fat total cells (CTF) were 1.62 x10(6) cells/mL and presented 98% of viability. These cells were taken for cultivation and after 20 days were counted 2.88 x10(6) cells/mL MSC. The same was done and after 20 days we quantified 4.28 x10(6) cells/mL MSC.
The lipectomy of adipose panicule is a very satisfactory method to extract stem cells from fat, quantitatively and qualitatively.
