Modulation of signaling pathways, which involves tendon development, regeneration, or homeostasis, is one of the potential modalities to facilitate proper regeneration of the injured tendon. Authors have previously reported that activation of Wnt/beta-catenin signaling suppressed the expression of tenogenic genes (i.e. Scleraxis (Introduction
Materials and Methods
In order to ensure safety of the cell-based therapy for bone
regeneration, we examined BM cells obtained from a total of 13 Sprague-Dawley (SD) green
fluorescent protein transgenic (GFP-Tg) rats were culture-expanded
in an osteogenic differentiation medium for three weeks. Osteoblast-like
cells were then locally transplanted with collagen scaffolds to
the rat model of segmental bone defect. Donor cells were also intravenously infused
to the normal Sprague-Dawley (SD) rats for systemic biodistribution.
The flow cytometric and histological analyses were performed for
cellular tracking after transplantation.Objectives
