Figure Legend Snippet: Characterization of the bone and osteoblast pathology. A . Photograph of the bone biopsy. B . Steady state SMS mRNA levels relative to GAPDH expression in cultured fibroblasts and osteoblasts. The patient’s cells did not differ significantly from controls. Data were derived by qRT-PCR analysis of 3 independent extractions of total RNA. C . Immunoblot showing steady state SMS protein expression in patient and control osteoblasts. ß-tubulin is shown as a loading control. D . Graph showing steady state SMS protein levels in the patient and control hBMSCs relative to ß-tubulin levels; there was no significant difference. The data are based on 3 independent experiments for each cell line. E - J . Immunofluorescent detection of SMS protein subcellular distribution in unaffected (E-G) and Patient II-1 (H-J) hBMSCs. SMS protein is shown in red and the nucleus is shown in blue. K . Graph quantifying immunoblot detected steady state SMS protein levels in the cytoplasm and nuclei of patient and control hBMSCs. The cytoplasmic expression was normalized to β-tubulin expression and the nuclear expression to p84 expression. L . Polyamine quantification in fibroblasts and osteoblasts. Note that the patient hBMSCs have a more striking imbalance of spermidine and spermine levels than do the patient fibroblasts, * p < 0.05, *** p < 0.005. M . Osteogenic potential of bone marrow stromal cells (hBMSCs) isolated from Patient II-1 sample is markedly lower than that of an unaffected control (cnt). The hBMSCs were seeded in triplicates (6x10 4 /12-well) and either kept untreated (-) or treated (+) with osteogenic differentiation media (see ) for 18 days. After the treatment, cells were fixed and were stained with Alizarin Red S to check for calcium deposition, a marker of osteogenic differentiation.
