Cover Story: Bone healing post-trauma presents significant health challenges. Impaired bone healing may result in severe complications requiring multiple surgical interventions. The use of biomaterial scaffolds to aid bone repair and healing has been found to be helpful in these situations. Biomorphic rattan-wood scaffolds (B-HA) present characteristics resembling the structure of the bone. Our study evaluated the ability of donor-derived bone marrow mesenchymal stromal cells (BMSCs) and culture-expanded mesenchymal stromal cells (cMSCs) to attach, survive and express their genes on these B-HA scaffolds to potentially aid bone repair.

  • Wenxing Wang,
  • Marcus Ardron,
  • Godfrey L. Smith and
  • Wenmiao Shu

In this work, we show that valve-based bioprinting induces no measurable detrimental effects on human-induced pluripotent stem cell-derived cardiomyocytes (hiPSC-CMs). The aim of the current study was three-fold: first, to assess the response of hiPS...
