NCAM transcription in hBM-MSCs. NCAM is transcribed from a single gene, located in chromosome 11q23.1, consisting of at least 25 exons. As a result of alternative splicing, the protein exists in multiple isoforms. Qualitative reverse transcription PCR analysis was performed to gain an overview of NCAM mRNA expression. a Five distinct isoforms are known and can be detected with a common primer pair (NCAM-All) or isoform-specific primers as indicated. b All known NCAM isoforms are expressed in hBM-MSCs at the mRNA level. NCAM-expressing neuroblastoma cell line kSK-N-SH served as a control. bp base pairs, GAPDH glyceraldehyde 3-phosphate dehydrogenase, MSC mesenchymal stromal cell, NCAM neural cell adhesion molecule, RT reverse transcriptase
