Hot dog‐like scaffolds are an excellent platform for cell delivery and differentiation. The proliferation, morphology, and relative genes expression of rBMSCs cultured on different scaffolds. a‐d) Confocal and SEM images of rBMSCs cultured on a) S‐AKT, b) H‐AKT, c) HD‐30AKT, and d) HD‐30AKT/Ica. e) The rBMSCs (red color) adhesion on the rod of HD‐AKT. f) The proliferation of rBMSCs after seeding in different kinds of scaffolds, showing hot dog‐like scaffolds are beneficial for cell proliferation. g) The relative osteogenic genes expression (OCN, Runx2, OPN, and ALP) of rBMSCs in scaffolds, indicating that the Ica release from the scaffolds promotes the relative osteogenic genes expression of rBMSCs (n = 6, *P < 0.05, and **P < 0.01.).
