Abstract (original English)

Mesenchymal stem cells (MSC) are increasingly being proposed as a therapeutic option for a variety of different diseases in human and veterinary medicine. At present, MSC are most often collected from bone marrow (BM) or adipose tissue (AT) and enriched and expanded in vitro before being transferred into recipients. However, little is known regarding the culture characteristics of feline BM-derived (BM-MSC) versus AT-derived MSC (AT-MSC). We compared BM-MSC and AT-MSC from healthy cats with respect to in vitro growth and cell surface phenotype. Mesenchymal stem cells isolated from AT proliferated significantly faster than BM-MSC. Phenotypic differences between BM-MSC and AT-MSC were not present in the surface markers assessed. We conclude that BM-MSC and AT-MSC are similar phenotypically but that cultures of AT-MSC are easier to generate because of their higher intrinsic proliferative rate. Thus, AT-MSC may be the preferred MSC for clinical applications where rapid and efficient generation of MSC is important.
