Abstract (original English)
Recently, cell-based approaches utilizing adipogenic progenitor cells for fat tissue engineering have been developed and reported to have success in promoting in vivo adipogenesis and the repair of defect sites. For autologous applications, human bone marrow-derived mesenchymal stem cells (MSCs) have been suggested as a potential cell source for adipose tissue engineering applications due to their ability to be isolated and ex vivo expanded from adult bone marrow aspirates and their versatility for pluripotent differentiation into various mesenchymal lineages including adipogenic. Due to the relatively low frequency of MSCs present within bone marrow, extensive ex vivo expansion of these cells is necessary to obtain therapeutic cell populations for tissue engineering strategies. Currently, utilization of MSCs for adipose tissue engineering is limited due to the attenuation of their adipogenic differentiation potential following extensive ex vivo expansion on conventional tissue culture plastic (TCP) substrates. In the present study, the ability of a denatured collagen type I (DC) matrix to preserve MSC adipogenic potential during ex vivo expansion was examined. Adipocyte-related markers and functions were examined in vitro in response to adipogenic culture conditions for 21 days in comparison to early passage MSCs and late passage MSCs ex vivo expanded on TCP. The results demon
