The role of donor age and gender in the success of human muscle precursor cell transplantation - Zurich Open Repository and Archive


Stölting, Meline N L; Hefermehl, Lukas J; Tremp, Mathias; Azzabi, Fahd; Sulser, Tullio; Eberli, Daniel (2017). The role of donor age and gender in the success of human muscle precursor cell transplantation. Journal of Tissue Engineering and Regenerative Medicine, 11(2):447-458.

Abstract

Autologous cell transplantation for the treatment of muscle damage is envisioned to involve the application of muscle precursor cells (MPCs) isolated from adult skeletal muscle. At the onset of trauma, these cells are recruited to proliferate and rebuild injured muscle fibres. However, a variety of donor-specific cues may directly influence the yield and quality of cells isolated from a muscle biopsy. In this study, we isolated human MPCs and assessed the role of donor gender and age on the ability of these MPCs to form functional bioengineered muscle. We analysed the cell yield, growth and molecular expression in vitro, and the muscle tissue formation and contractility of the bioengineered muscle, from cells isolated from men and women in three different age groups: young (20-39 years), adult (40-59 years) and elderly (60-80 years). Our results suggest that human MPCs can be successfully isolated and grown from patients of all ages and both genders. However, young female donors provide fast-growing cells in vitro with an optimum contractile output in vivo and are therefore an ideal cell source for muscle reconstruction. Taken together, these findings describe the donor-related limitations of MPC transplantation and provide insights for a straightforward and unbiased clinical application of these cells for muscle reconstruction.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
