    Beyotime alizarin red s staining kit
    In vitro validation of D-Bmp2@M osteogenic efficacy and inhibition of ectopic ossification. a. Schematic diagram of the osteoblast-bone Transwell model. Bmp2/D-Bmp2@M microspheres or free Bmp2/D-Bmp2 were loaded in the upper chambers, MC3T3-E1 cells were cultured on two coverslips (one of which was precoated with HA) in the lower compartments, and the medium was refreshed every day for 7 or 14 days. Alkaline phosphatase (ALP) <t>and</t> <t>Alizarin</t> <t>Red</t> <t>S</t> (ARS) staining were performed at days 7 and 14, respectively. b. Osteogenic differentiation staining: ALP (early-stage, day 7) and ARS (late-stage, day 14) staining. Scale bar: 200 μm. c. ALP activity was quantitatively analyzed using an ALP kit (n = 3 per group). d. Relative quantitative analysis of ARS staining was performed at an OD of 562 nm (n = 3 per group). e. qPCR analysis of Bmp2 signaling-related mRNA in MC3T3-E1 cells (n = 3 per group). f. Schematic diagram of the muscle-bone Transwell model. Bovine bone slices were co-incubated with Bmp2/D-Bmp2@M or free Bmp2/D-Bmp2 in the upper chambers, and C2C12 cells were cultured in the lower chambers and the medium was refreshed every day for 7 days. D-Bmp2 and Bmp2 retention on bone slices and ALP staining of C2C12 cells were analyzed on day 7. g. Representative fluorescence imaging of bone slices incubated with AF647-conjugated anti-Flag antibodies (above) (yellow arrows: bone slice) and C2C12 ALP staining images (below), scale bar: 200 μm. h. AF647-conjugated anti-Flag antibody fluorescence intensity quantification in bone slices (n = 3 per group). i. Quantification of ALP activity in C2C12 cells (n = 3 per group). j. qPCR analysis of Bmp2 signaling-related mRNA in C2C12 cells (n = 3 per group). The data are presented as the means ± SDs. One-way ANOVA was used for multiple comparisons. Significance levels: ns (not significant), ∗ p < 0.05, ∗∗∗ p < 0.001, ∗∗∗∗ p < 0.0001.

Here, we present a hierarchical granular hydrogel (GH) gradient scaffold that recreates the depth-wise transitions of the osteochondral interface and supports spatially organized regeneration.. The scaffold is fabricated through a modular layer-by-layer strategy in which GH building blocks with independently tunable compositions, crosslinking densities, and bioactive cues are sequentially integrated onto ultrafine melt electrowritten (MEW) fibrous architectures that define the defectspecific geometry.
