Transcription profiling of human passage 1 mesenchymal stem cells from bone marrow stroma during 15 day culturing

ABSTRACT: To study the gene expression changes in mesenchymal stem cells from bone marrow stroma (MSCs) during in vitro expansion (from low density), passage 1 MSC were grown in culture for 15 days with medium change every 2-3 days. Samples for microarrays were taken at day 5 (early log-phase), 10 (late log-phase) and 15 (stationary phase). The data was queried for expression changes in Wnt signaling molecules and cell surface markers. Several components of the canonical Wnt signaling pathway were expressed, including Dkk-1; Wnt-5a; alpha-catenin; beta-catenin; frizzled 1, 4, 6, and 7; disheveled; glycogen synthetase kinase 3 beta; and glycogen synthetase kinase 3 alpha. In addition, the expression of over 10 cell surface transcripts decreased and an almost equal number increased during expansion.
