Figure Lengend Snippet: Perfusion micro-physiological devices (MPDs) support long-term bone culture. (A) Schematics elucidating the 3D bone co-culture in HAP containing scaffolds in a perfusion-based single MPDs for addressing challenges during long-term bone co-cultures, (B) Schematics for single organ perfusion-based MPD construction having a single well volume of 2.26 cm 3 for housing a cylindrical 3D scaffold (0.16 cm 3 ) and connected with microchannels (500 μm in diameter) for maintaining the flow, (C – D) Flow velocity and pressure simulations within the single chambered compartment, (E) Quantification of metabolic activity (resazurin assay) of hMSCs and THP-1 co-cultured cells on 3D scaffolds/cryogels within the perfusion-based MPDs (n = 3), ( F ) Live (CAM-green)/dead (PI- red) staining of bone co-culture 3D scaffolds/cryogels revealed the efficiency of perfusion systems over static system over a period of 21-day culture (green = live cells; red = dead cells) (n = 6), ( G ) cell apoptosis (lactate dehydrogenase assay- LDH) (n = 3), ( H ) Osteoblastic activity (alkaline phosphatase assay- ALP) (n = 3) and ( I ) osteoclastic activity (tartarate resistant acid phosphatase assay-TRAP) (n = 3) of bone co-culture scaffolds revealed significant improvement in the day 14 and 21 functional activity. All data presented as Mean ± S.D., where ∗p ≤ 0.05, ∗∗p ≤ 0.01, ∗∗∗p ≤ 0.001 were considered as significant and ns: as non-significant.
