Description
Summary:The recapitulation of cartilage/bone formation via guiding induced pluripotent stem cells (iPSCs) differentiation toward chondrogenic mesoderm lineage is an ideal approach to investigate cartilage/bone development and also for cartilage/bone regeneration. However, current induction protocols are time-consuming and complicated to follow. Here, we established a rapid and efficient approach that directly induce iPSCs differentiation toward chondrogenic mesoderm lineage by regulating the crucial Bmp-4 and FGF-2 signaling pathways using a 3D rotary suspension culture system. The mechanical stimulation from 3D rotary suspension accelerates iPSCs differentiation toward mesodermal and subsequent chondrogenic lineage via the Bmp-4-Smad1 and Tgf-β-Smad2/3 signaling pathways, respectively. The scaffold-free homogenous cartilaginous pellets or hypertrophic cartilaginous pellets derived from iPSCs within 28 days were capable of articular cartilage regeneration or vascularized bone regeneration via endochondral ossification in vivo, respectively. This biomimetic culture approach will contribute to research related to cartilage/bone development, regeneration, and hence to therapeutic applications in cartilage-/bone-related diseases.
