Figure Lengend Snippet: Morphological changes in BM-MSCs during osteogenic differentiation over 28 days in media with different supplement compositions. Cells were differentiated in DM1–DM4 media. Cell morphology was assessed by bright-field microscopy on days 0, 7, 14, and 28. Representative images show progressive changes in cell shape and density indicative of osteogenic differentiation. Scale bar = 200 μm

Figure Lengend Snippet: Von Kossa staining of BM-MSCs cultured for 28 days in different osteogenic media reveals varying degrees of mineralization. Cells were differentiated in DM1–DM4 media. Black precipitates indicate calcium phosphate deposits, demonstrating the extent of ECM mineralization. Scale bar = 500 μm

Figure Lengend Snippet: Alizarin Red staining of BM-MSCs cultured in different osteogenic media (DM1–DM4) at various time points reveals differences in calcium deposition. Cells were cultured for 7, 14, and 28 days in DM1–DM4 media. Red staining indicates the presence of calcium-rich deposits. The most extensive mineralization was observed in DM4, particularly on day 14 and 28, whereas DM2 (lacking DEX after day 7) showed the weakest staining. Scale bar = 200 μm

Figure Lengend Snippet: A Quantification of calcium deposition in BM-MSCs cultured in osteogenic media DM1–DM4 using Alizarin Red extraction. Absorbance was measured at 562 nm and expressed in arbitrary units. B ALP activity in BM-MSCs cultured in different osteogenic media (DM1–DM4) at various time points. ALP activity was normalized to total protein content and expressed as enzyme activity per milligram of protein per milliliter of lysate. All data represent means ± standard deviations from three independent biological replicates. Statistical significance was assessed using a two-tailed unpaired t -test and is indicated by asterisks (* P < 0.05, ** P < 0.01, *** P < 0.001).

Figure Lengend Snippet: Visualization of actin cytoskeleton and mitochondrial network in BM-MSCs undergoing osteogenic differentiation in various media (DM1–DM4). Cells were stained with Phalloidin–TRITC (red) to visualize F-actin filaments and MitoTracker™ Red CMXRos (red) to detect mitochondria. Cell nuclei were counterstained with NucBlue™ (blue). Images were processed using ImageJ software (W. S. Rasband, U.S. National Institutes of Health, Bethesda, MD, USA). Scale bar = 100 μm

Figure Lengend Snippet: Relative expression levels of osteogenic marker genes during BM-MSCs osteodifferentiation in different supplementation conditions. Transcript levels of A RUNX2 , B ALP , C OCN , and D BMP2 were measured by qRT-PCR at days 7, 14, and 28 in BM-MSCs cultured in osteogenic media DM1–DM4. Gene expression was normalized to the housekeeping gene GAPDH and expressed relative to undifferentiated control levels. All data are presented as means ± standard deviation from three biological replicates. Asterisks indicate statistically significant differences (* P < 0.05, ** P < 0.01; unpaired two-tailed t -test).

Figure Lengend Snippet: Overview of experimental workflow. Timeline of BM-MSCs culture, induction of osteogenic differentiation in four different media (DM1–DM4), and time points of sample collection. The diagram illustrates key methodological steps, including morphological assessment, von Kossa and Alizarin Red staining, ALP activity and total protein quantification, immunofluorescence staining (F-actin and mitochondria), and gene expression analysis by qRT-PCR. Sampling was performed at days 0, 7, 14, and 28, as indicated. Created in Biorender.com

Figure Lengend Snippet: Volcano plots depicting differentially abundant phospho-peptides ( a ) and proteins ( b ) in JMSU1-RS cells compared to JMSU1 cells. Red and blue dots indicate significantly upregulated and downregulated proteins/phospho-peptides in JMSU1-RS cells, respectively, with a fold change > 2 and p < 0.05. c Phospho-RTK array showing upregulated pMET and pEGFR in JMSU1-RS cells. d Western blot analysis of JMSU1 and JMSU1-RS cells treated with the indicated concentrations of erdafitinib (Erd) for 12 h. e Quantitative RT-PCR analysis showing MET mRNA upregulation in JMSU1-RS cells ( n = 3). f Digital PCR analysis of MET gene copy number in JMSU1 and JMSU1-RS cells ( n = 3). The dotted line represents the normal diploid copy number (two copies), as observed in BM-MSCs. Data are presented as mean ± SD; * p < 0.05, *** p < 0.001, **** p < 0.0001; statistical significance determined by unpaired t-test ( e ) and Tukey’s test ( f ).
