An Intervertebral Disc (IVD) Regeneration Model Using Human Nucleus Pulposus Cells (iHNPCs) and Annulus Fibrosus Cells (iHAFCs)

open access: yesAdvanced Healthcare Materials, EarlyView.
This study investigates hTert‐immortalized human nucleus pulposus (iHNPCs) and annulus fibrosus (iHAFCs) cells for intervertebral disc (IVD) regeneration and spinal fusion models. A 3D‐printed citrate‐based scaffold loaded with BMP9‐stimulated iHAFCs and BMP2‐stimulated iHNPCs effectively promotes bone and cartilage formation, mimicking the IVD ...

Longer Acting Injectable: Continuous, Linear Release of a Progestin Contraceptive From an Oxidized Porous Silicon Host

open access: yesAdvanced Healthcare Materials, EarlyView.
Progestin drugs are loaded into a mesoporous silicon dioxide host by melt‐infiltration. Drugs that decompose at or close to their melting point can be loaded by the addition of cholesterol, which acts as a melting point suppressor. High mass loading of the drug is achieved, and dissolution of the composite is controlled by the nanoscale properties of ...
