The Effect of Amino Acids on the Formation of Amorphous Calcium Carbonate Nanoparticles

open access: yesAdvanced Functional Materials, EarlyView.
Biomineral formation often proceeds via the assembly of amorphous calcium carbonate (ACC) nanoparticles with narrow size distributions. Using in situ SAXS coupled to a stopped‐flow device, we follow synthetic ACC formation with a 10 ms time resolution and show that amino acids narrow the size distribution at low supersaturation, highlighting their key ...

Human Endometrial Extracellular Matrix Hydrogel Facilitated Endometrial Mesenchymal Stem Cells for Endometrial Regeneration

open access: yesAdvanced Healthcare Materials, EarlyView.
Adequate thickness of the uterine lining is crucial for women with thin or damaged endometrium to achieve pregnancies. Endometrial mesenchymal stem cells (eMSC) can facilitate the cyclical repair and regeneration of the human endometrium. In this study, the human endometrium derived extracellular matrix hydrogel supports the growth of eMSC promoting ...
