Abstract
Multicellular aggregates have been widely utilized for regenerative medicine; however, the heterogeneous structure and undesired bioactivity of cell-only aggregates hinder their clinical translation. In this study, we fabricated an innovative kind of microparticle-integrated cellular aggregate with multifunctional activities in angiogenesis and osteogenesis, by combining stem cells from human exfoliated deciduous teeth (SHEDs) and bioactive composite microparticles. The poly(lactide-co-glycolide) (PLGA)-based bioactive microparticles (PTV microparticles) were ∼15 μm in diameter, with dispersed β-tricalcium phosphate (β-TCP) nanoparticles and surface-modified vascular endothelialcadherin fusion protein (hVE-cad-Fc). After co-culturing with microparticles in U-bottomed culture plates, SHEDs could firmly attach to the microparticles with a homogeneous distribution. The PTV microparticle-integrated SHED aggregates (PTV/SHED aggregates) showed significant positive CD31 and ALP expression, as well as the significantly upregulated osteogenesis makers (Runx2, ALP, and OCN) and angiogenesis makers (Ang-1 and CD31), compared with PLGA, PLGA/β-TCP (PT) and PLGA/hVE-cad-Fc (PV) microparticle-integrated SHED aggregates. Finally, in mice, 3 mm calvarial defects filled with the PTV microparticle-integrated SHED aggregates achieved abundant vascularized neo-bone regeneration within 4 weeks. Overall, we believe that these multifunctional PTV/SHED aggregates could be used as modules for bottom-up regenerative medicine, and provide a promising method for vascularized bone regeneration.

Abstract
Reproductive engineering techniques are essential for assisted reproduction of animals
and generation of genetically modified animals. They may also provide invaluable research
models for understanding the mechanisms involved in the developmental and reproductive
processes. At the RIKEN BioResource Center (BRC), I have sought to develop new
reproductive engineering techniques, especially those related to cryopreservation,
microinsemination (sperm injection), nuclear transfer, and generation of new stem cell
lines and animals, hoping that they will support the present and future projects at BRC. I
also want to combine our techniques with genetic and biochemical analyses to solve
important biological questions. We expect that this strategy makes our research more
unique and refined by providing deeper insights into the mechanisms that govern the
reproductive and developmental systems in mammals. To make this strategy more effective,
it is critical to work with experts in different scientific fields. I have enjoyed
collaborations with about 100 world-recognized laboratories, and all our collaborations
have been successful and fruitful. This review summarizes development of reproductive
engineering techniques at BRC during these 15 years.
