2.1 GC的添加提高了压缩模量 To determine the effects of GC on the mechanical properties of GelMA-GC hydrogels, compression test and swelling analysis were conducted with two different photo-cross-linking systems, Ru/SPS and LAP, respectively. GC significantly increased the CM of hydrogels in both ...
Swelling ability of hydrogels, which is influenced by hydrogel pore size, can indicate the degree of hydrophilicity and is an essential feature of the cornea. The measured mass swelling ration of the native cornea and pure GelMA hydrogel was 14.5 ± 0.59 and 16.7 ± 0.51 (The data...
To characterize the physical properties of the composite scaffold, the mechanical strength, swelling ratio and internal microstructure were tested. The biocompatibility of the GelMA/CMCS scaffold was evaluated by live/dead test and CCK-8. To evaluate the cell distribution, CD31 expression and ...
1h). The swelling ratio of Fe2O3/GelMA hydrogels decreased with the amount of Fe2O3 nanoparticles, which may contribute to the increased cross-linking of hybrid hydrogel (Fig. 1i). Interestingly, the internal mechanical properties of these hydrogels were significantly improved by enhancing their...
placed in 50 mL centrifuge tubes with ultrapure water, after swelling for a certain time at 37 °C, the hydrogels were taken out, filter paper were used to absorb the free water on the surface of the hydrogels, after which the wet weight (Wt) of the hydrogel after swelling were measured...
Finally, the hydrogel was freeze-dried and the porous scaffold were obtained. The scaffold samples were characterized via SEM, FTIR, mechanical compression test, swelling test and degradation test. The in vitro cellular responses to the GelMa/ES-HA composite scaffold were ...
To determine the effects of GC on the mechanical properties of GelMA-GC hydrogels, compression test and swelling analysis were conducted with two different photo-cross-linking systems, Ru/SPS and LAP, respectively. GC significantly increased the CM of hydrogels in both photoinitiator groups (Figure1A...
The presence of PCL-MA in the hybrid resins improved the 3D printing fidelity compared to the neat GelMA resins, while GelMA provided the hybrid materials with enhanced swelling and proliferation of seeded cells. We further demonstrated the transferability of our resin formulation to native organ-...
The degree of degradation was estimated by the measurement of hydrogel weight loss in comparison to the original wet weight after swelling. Four separate constructs per time point and digestion condition were used in this experiment. 2.8. Cell Viability and Proliferation The viability and proliferation...
supplementation on the spreading, proliferation, and osteogenic differentiation of AD-MSCs. In addition, the influence of hPL on hydrogel properties was also investigated. We demonstrate that the addition of hPL enhanced AD-MSC spreading, proliferation, and osteogenic differentiation in a concentration-de...
