Human Umbilical Cord Mesenchymal Stem Cells Encapsulated with Pluronic F-127 Enhance the Regeneration and Angiogenesis of Thin Endometrium in Rat via Local IL-1β Stimulation

Figure 2

PF-127 hydrogel possesses larger interconnected pore and higher biocompatible capacity compared to C/GP hydrogel. (a) Photographs of PF-127 and C/GP hydrogel. (b) SEM images of PF-127 and C/GP after 24-hour freeze drying process.  μm. (c) Quantification of porosity of PF-127 and C/GP hydrogel. Data was reported as of 5 SEM images with 200× magnification, tested for significant difference () using Student’s -test. (d) Comparison of pore size of PF-127 and C/GB hydrogel. Results were presented as of approximately 50 pores from 5 SEM images with 100× magnification. Significant difference test was performed with Mann–Whitney rank sum test (). (e) Q-PCR analyzed the relative gene expression of inflammatory factors (Tnfa, Ifng, and Il2). Data was reported as . Student’s -test was applied for significant difference (), .
