Is there a need for smooth muscle cell transplantation in urethral reconstruction?
SMC-seeded tubular collagen scaffolds improved urethral regeneration in this rabbit model. Such constructs may be valuable for repair of severe urethral diseases.
Our results suggested that 50% ethanol extracts of root-bark of Sambucus Williamsii Hance can accelerate fracture healing by recruitment of osteoblasts at the fracture site and through up-regulation of the BMP-2 signaling pathway.
